Quantum Computing

Quantum Computing

(9 minutes of reading)

If you're a programmer and have been following emerging trends in the world of technology, you've probably heard about quantum computing. This technology promises to revolutionize the way we process information and has the potential to play a transformative role in areas such as artificial intelligence, cryptography, and simulation of complex systems. But what is the essence of quantum computing and how does it differ from the classical computing we know?

Come read our article to find out more about this hot topic!


BASIC PRINCIPLES OF QUANTUM COMPUTING

The central difference between classical and quantum computing lies in information and how it is manipulated.

In classical computing, the fundamental unit of information is the bit, which can be in one of two states: 0 or 1.

In quantum computing, the unit of information is the qubit (quantum bit), which can be in a superposition state, representing 0 and 1 simultaneously.

This ability for a qubit to be in superposition is one of the pillars of quantum mechanics. Instead of having a definitive answer like in the classical world, superposition allows us to calculate several possibilities simultaneously. However, when a qubit is measured, it "collapses" into one of the possible states, 0 or 1.

Another fundamental property is entanglement, where qubits can become interdependent, such that the state of one qubit can depend on the state of another, regardless of the distance that separates them. This allows information to be transmitted in ways previously considered impossible in the classical world.


HOW TO PROGRAM QUANTUM COMPUTERS

Given the fundamentally different nature of quantum computers, quantum programming requires a different approach. Instead of sequential instructions, quantum programming involves applying mathematical operators, known as quantum gates, to qubits. These gates allow us to manipulate superpositions and interlacing, enabling massively parallel operations.

Quantum programming languages and frameworks, such as Microsoft's Q#, IBM's QuTiP, and Qiskit, have been developed to facilitate the creation of quantum algorithms. These frameworks allow programmers to design quantum circuits and test their functionality, often using simulators before running on a real quantum computer.


WHAT CAN QUANTUM COMPUTERS DO?

The power of quantum computers doesn't mean they will replace our traditional PCs and servers. In fact, they are suited to specific tasks that are inherently difficult for classical computers.

Shor 's Algorithm, which can factor large numbers in polynomial time, a problem for which we do not have an efficient solution in classical computers. If implemented, this algorithm could break many cryptographic systems currently in use.

Another promising application is the simulation of quantum systems. For example, understanding chemical reactions at the molecular level or designing new materials with desired properties can be much more efficient with the help of quantum computers.


CHALLENGE FOR PROGRAMMERS

Despite its great potential, quantum computing presents challenges. Decoherence, where quantum information is lost due to interactions with the environment, is a significant problem. Errors are also inherently more problematic in quantum computing, requiring advanced error correction techniques.

For programmers, this means that developing quantum algorithms is not just about optimizing efficiency, but also about ensuring accuracy in a system that is fundamentally prone to error.


FUNDAMENTALS OF QUBITS AND QUANTUM GATES

As previously mentioned, unlike bits, which clearly represent a 0 or a 1, qubits operate in a superposition state. In other words, a qubit can represent 0, 1, or both simultaneously. When we talk about 'both', we refer to different probabilities associated with a qubit of being measured as 0 or 1. This characteristic is vital to the parallelism inherent in quantum computing.

Quantum gates are operators that act on one or more qubits. Just like in classical computing, where we have logical gates (AND, OR, NOT), in quantum computing we have gates that manipulate qubits, such as the Hadamard , Pauli-X, Pauli-Y, Pauli-Z and CNOT gates, just to name a few.


QUANTUM ENTANGLEMENT

Entanglement is one of the most intriguing and powerful properties of quantum mechanics. Entangled qubits have their states dependent on each other, even if they are separated by large distances. This means that the measurement of one qubit immediately determines the state of the other, regardless of the distance separating them.


DEVELOPING QUANTUM ALGORITHMS

Quantum programming is not just a matter of learning new syntax; it's a fundamental reassessment of how we approach computational problems. For example, Grover's algorithm allows faster searching in an unstructured database than any classical algorithm. While a classical algorithm may need N attempts to find an item in a database of size N, Grover's algorithm only needs about ?N attempts.


QUANTUM COMPUTING AND CRYPTOGRAPHY

The potential threat of Shor 's algorithm to current RSA-based cryptography raises questions about the security of many of our digital transactions. However, there is also a positive side: quantum cryptography, which uses the properties of quantum mechanics to create secure keys and detect any interception attempts.


TOOLS AND PLATFORMS FOR PROGRAMMERS

Several companies and research organizations have developed frameworks for quantum programming:

IBM's Qiskit: One of the most popular libraries, Qiskit is an open-source tool that allows programmers to create, simulate, and run quantum programs.

Q# from Microsoft: Integrated with Visual Studio, Q# is a high-level quantum programming language with its own development suite.

Cirq by Google: Specializing in creating quantum circuits, Cirq was designed to make it easier for researchers to upload experiments to Google's quantum processors.


THE FUTURE OF QUANTUM COMPUTING

What can we expect from quantum computing in the future? For many experts, the hope is to achieve "quantum supremacy," the point at which a quantum computer can perform a task that would be virtually impossible for a classical computer.

Furthermore, the advent of more robust and affordable quantum computers will see a rise in "hybrid computing", where quantum and classical computers work together to solve problems.


CONCLUSION

For programmers, quantum computing represents an exciting frontier with unprecedented challenges and opportunities. While the learning curve is steep, the reward is the ability to work at the forefront of the next computing revolution. Whether learning about the fundamental properties of quantum mechanics or exploring new algorithms and applications, there is a lot to discover and innovate, this is certainly an exciting time. With quantum hardware emerging and programming tools becoming more mature, there are significant opportunities for innovation.

The transition to quantum computing will not be immediate nor will it completely replace classical computing. Instead, a coexistence is expected, where quantum and classical computers work together to solve problems. For programmers, understanding this new form of computing will be critical to staying relevant in a rapidly evolving technological world.

As you delve deeper into the world of quantum programming, challenge yourself to think beyond traditional paradigms. After all, we are on the cusp of a new era in computer science, and the future promises to be quantum!

Framework

Framework

(11 minutes of reading)


In programming, a framework is a pre-built set of tools, libraries, and guidelines that provide reusable components to help developers build applications more efficiently and quickly. A framework provides a foundation for building software by abstracting away common functionality, allowing programmers to focus on application-specific logic rather than “reinventing the wheel” daily.

Frameworks bring functionality already determined to speed up the process and prevent developers from having to rewrite these functions frequently. They are tools that establish an intermediary between the programmer and the code of an application, as a kind of communication interface. Thus, they automate some questions, leaving the heavy work more abstract and hidden for people in the area.


WHAT ARE THE MOST USED FRAMEWORKS?

The most used frameworks in programming vary depending on the programming language and the specific domain of the application and its specialty, such as front-end, back-end or mobile.

However, here we made a list of the most used frameworks in different programming languages. Here they are:


FRAMEWORK FOR JAVASCRIPT

ReactJS: A popular framework for creating user interfaces for web and front-end applications. It's Facebook´s framework and it was created to overcome the challenges of a single- page app (SPA). A SPA is a page that has independent elements, one of which can be reloaded while the others remain static. React made development easier, but went further, because it modernized JavaScript syntax and allowed virtual DOM (Website Tag Hierarchy) manipulation for faster interfaces. It's a very simple pattern to learn, with a large and helpful community.

AngularJS: It is a comprehensive framework for building large-scale web applications. It is one of the most famous front-end frameworks and a direct competitor to React. Angular is a very good option for anyone looking for a widely used standard with a huge community. It is a technology that makes development more robust and readable by bringing innovations such as Data Binding and greater test support.

Vue.js: is a progressive JavaScript framework for building user interfaces. It is a good example of a progressive framework, that is, it can be used in small parts of the system and does not lock the programmer to a single option. Vue.js has great documentation and a huge community. It also brings some elements that we already mentioned, such as data binding, virtual DOM and support for SPAs.

Express: is a back-end framework, used in addition to Node.js. It's a great option to manage back issues, such as routes, HTTP requests and APIs, in a practical and fast way.


FRAMEWORKS FOR PYTHON

Django: is a high-level web framework that follows the model view controller (MVC) architecture pattern. Django is an alternative to dealing with Python in the backend, as it allows managing microservices, manipulating databases, user authentication, RSS feed, among others. For databases in particular, Django supports several relational types, such as PostgreSQL, MySQL and SQLite .

Another highlight of Django is its focus on security and protection of websites. It works to help combat false requests, SQL injection and other common attacks on web pages. As a good standard for the backend, it allows the creation of robust and secure applications, which will not cause headaches for administrators or users.

Flask: is a lightweight web framework that offers flexibility and simplicity for building web applications. It’s on the backend of web applications and is known as a microframework, due to its simplicity and speed of operation. In addition, it is very versatile and important for small projects and for more robust applications. It must be said that Flask tries to apply the philosophy of Python, with minimalism and code cleanliness to generate more interesting results. So it is called “pythonic” and has more impressive performance.


FRAMEWORKS FOR RUBY

Ruby on Rails: is a powerful and opinionated framework that emphasizes convention over configuration for web application development.


FRAMEWORKS FOR JAVA

Spring: is a robust and widely used framework for building enterprise-level Java applications.


FRAMEWORKS FOR PHP

Laravel: Is a popular framework that provides expressive syntax and a rich feature set for web and backend development. Its popularity is related to several factors, such as: community support, documentation, ease of use, performance and availability of third-party libraries and extensions. Additionally, these frameworks often have a large user base, which makes it easier for developers to find resources, tutorials, and solutions to common problems. It also allows access to several types of relational databases, enables scalability, and presents a great community with several important topics, accessible in a click.


ADVANTAGES OF USING FRAMEWORKS

Using a framework offers several benefits to developers. Here is a list of some of them:

1- Efficiency: Frameworks provide a structured and organized approach to development. They offer prebuilt components, libraries, and tools that can significantly speed up the development process. Developers can leverage existing functionality and focus on implementing features and logic specific to their applications rather than reinventing basic building blocks.

2- Productivity: Frameworks often come with built-in features and functionality that address common development tasks like database manipulation, routing, authentication, and form validation. These features reduce the amount of code developers must write, resulting in faster development and greater productivity.

3- Standardization: frameworks promote best practices and follow established design standards. They enforce a consistent structure and coding style, making it easy for developers to collaborate on projects. Standardization also leads to better code maintainability and readability, as other developers who are familiar with the framework can quickly understand and work with the code base.

4- Community and Support: Popular frameworks have large and active developer communities. That means you can find extensive documentation, tutorials, forums, and resources to help you learn and troubleshoot. Community support can be invaluable when you encounter challenges or need guidance when working with the framework.

5- Scalability: Frameworks often provide scalability features that allow your application to handle increased user loads and data volumes. These can include caching mechanisms, load balancing, and other performance optimizations that help your application scale efficiently.

6- Security: Frameworks generally address common security vulnerabilities and provide built-in measures to protect against attacks such as cross-site scripting (XSS), cross-site request forgery (CSRF) and SQL injection. By using a framework, you can benefit from these security measures without having to implement them from scratch.

7- Ecosystem and third-party integrations: frameworks often have a wide variety of extensions, plug-ins and libraries created by the community. They can provide additional functionality, integrations with popular services, or extend framework capabilities. Leveraging the existing ecosystem can save time and effort in implementing complex features.

While using a framework offers many advantages, it is essential to choose the right framework for your project based on your specific requirements and the experience of your development team. Additionally, some projects may have unique requirements that may not fit well within the constraints of a particular framework. In these cases, a custom solution or less opinionated framework may be more suitable.


APPLICATIONS

Frameworks can be used to develop a wide range of applications in different domains. Here are some examples of applications where frameworks are commonly used:

Web Applications: Frameworks are used extensively to build web applications, including content management systems (CMS), eCommerce platforms, social media platforms, blogging platforms, and more. Web frameworks provide the necessary tools to handle routing, request handling, database interactions, user authentication, and front-end development.

Mobile Apps: Frameworks are available for building mobile apps for both iOS and Android platforms. These frameworks often leverage web technologies like HTML, CSS, and JavaScript to create cross-platform mobile apps that can be deployed across multiple platforms using a single codebase.

APIs development: Frameworks are used to develop APIs that allow applications to communicate and share data with each other. These frameworks provide features for handling requests, routing, data serialization, authentication, and security.

Desktop Apps: Frameworks are available to develop desktop apps on different platforms. These frameworks provide a set of tools and libraries for creating graphical user interfaces (GUIs), handling user interactions, and performing various tasks associated with desktop applications.

Game Development: Frameworks designed for game development provide game engines, physics simulation, rendering capabilities, and other tools needed to create games. These frameworks often include features to handle graphics, audio, input, and game logic.

Data analysis and machine learning: frameworks like TensorFlow, PyTorch and scikit-learn are widely used in data and machine analysis applications learning. They provide a high-level interface, optimized algorithms, and computational resources for working with large datasets, training machine models learning and perform data analysis tasks.

Internet of Things (IoT): Frameworks are used in the development of applications for IoT devices, including home automation systems, smart sensors, and industrial automation. These frameworks provide the necessary connectivity, data management, and control capabilities for building IoT applications.

As mentioned earlier, it's important to note that choosing a framework depends on the specific requirements of your application, the programming language you are using, and the experience of your development team. Different frameworks excel in different areas, so it's crucial to evaluate and select the one that best fits your needs.

Mastering what a framework is essential for anyone who wants to work with programming. It is essential to achieve career success and enter that much-desired vacancy. In this sense, it is essential to understand how these solutions are used, their benefits and to know which ones are most used now.

ChatGPT

ChatGPT

(7 minutes of reading)


Who hasn't heard of these 3 letters in recent months: GPT? This is certainly one of the most searched and commented subjects in recent times, regardless of your area of expertise.

Now what is ChatGPT? The acronym GPT stands for Generative Pre-Trained Transformer. ChatGPT is an AI powered intelligent virtual assistant based on deep learning, in an online chatbot format. It was developed by OpenAI and officially released in November 2022, but it has existed since 2019.

Chatbot is a computer program that simulates a human being in conversation with people. The purpose of a chatbot is to answer questions in a way that people have the impression of talking to another person and not to a computer program. After submitting questions in natural language, the program queries a knowledge base and then provides an answer that tries to imitate the human behavior.

ChatGPT uses an algorithm based in neural networks that allows to establish a conversation with the user by processing a huge volume of data. It leans in thousands of human language examples, enabling technology to understand in depth the context of user requests and can respond to questions very precisely.

We found in ChatGPT a more dynamic and flexible technology than any other chatbot, which is why GPT can develop much more complex conversations and respond to an infinite number of number of questions.


HOW DOES CHATGPT WORK?

By accessing the OpenAI website you start an online conversation. ChatGPT gathers text data available on the internet.

It works from an updated knowledge base that allows it to decode words and offer textual answers to users. The biggest difference between it and Google is that ChatGPT does not retrieve information but creates phrases and complete texts in real time.

ChatGPT is updated and fed with new information all the time. The model works collaboratively, as the users can correct the information provided by the tool.

Through a APIs, ChatGPT can also be integrated with other tools, such as: Word, Bing, Chatbots and WhatsApp Business


FACTS ABOUT CHATGPT

There are several interesting and curious facts about ChatGPT:

1- It was trained on a huge set of text data, which included everything from books, articles, news and even posts on social media and internet forums. This allowed the model to develop a rich understanding of natural language.

2- It is a generative model, that is, it can generate a new text with style and tone like the input text. This makes it an ideal tool for tasks like text completion, where you can predict the next word in a sentence based on the context and meaning of the previous words.

3- It can produces text very similar to that written by human beings. This generated concerns about possible misuse of the model, such as to generate fake news or impersonating individuals online.

4- OpenAI launched several versions of the ChatGPT model, including the GPT-2 and GPT-3 models, widely used by developers and researchers for a variety of natural language processing tasks. 

5- It can be used for a variety of applications including chatbots, content generation, language translation, and even art and music generation.

6- GPT-3 is one of the biggest language models already developed with more than 175 billion parameters.

7- Can produce a wide variety of textual styles and genres, including poetry, jokes, and even political speeches.

ChatGPT revolutionized the field of natural language processing and opened news possibilities for communication and human x machine interaction.


CODE

ChatGPT is a natural language processing model based on the GPT architecture. GPT architecture, as said earlier, stands for generative pre-trained transformer, and it is a kind of deep learning model that uses a transformer-based neural network to generate natural language text.

The ChatGPT model is trained into a large set of text data, which allows to generate coherent and relevant answers to a wide range of natural language inputs. The model uses a combination of unsupervised pre-training and fine-tuning on task-specific data to achieve peak performance on a variety of language tasks, including text generation, summarizing, and answering a wide range of questions.

The ChatGPT code is owned by OpenAI. However, OpenAI launched several models pre-trained that can be used for various natural language processing tasks. In addition, OpenAI offers API services that allow developers to integrate ChatGPT model features into their own applications. The APIs can be accessed using a variety of programming languages, including Python, Java and Ruby, among others.

A transformer architecture consists in an encoder and a decoder, which work together to generate texts in natural language. The encoder receives one sequence of tokens (usually words or subwords) and generates one String representation that captures the context and meaning of the text. The decoder uses this representation to generate a new text, either predicting the next word in one sentence or generating one sentence or complete paragraphs.

The code for pre-trained models provided by OpenAI is written in Python and uses PyTorch deep learning framework. Developers can use the models by importing the pre-trained model code and providing input text. The model can generate output text based on the input text and the context of the pre-trained model.

Docker

Docker

(7 minutes of reading)


In recent years, Docker has become a buzzword in the tech industry. But what exactly is Docker and how does it work?

In today's text we will explore the fundamentals of Docker and how it can help developers and organizations to simplify their processes. Come check out everything about Docker right now!


WHAT IS DOCKER?

Docker is an open-source platform that allows software developers to build, deploy and run applications in an independent environment.

Docker has become a popular tool for developers because of its ability to provide a lightweight, secure, and isolated environment for applications.

The software helps eliminate the need for developers to spend time setting up their own servers or creating complicated virtual machines.

Docker is made up of several components, including a server, runtime engine, image repository, and command line interface (CLI).

The server runs the Docker engine that manages all images and containers.

Images are created from existing application code and deployed as read-only templates, while containers are isolated environments that keep applications running.

The CLI allows users to interact with the Docker instance by providing commands such as build, run, or stop on an image or container.


DOCKER x VIRTUAL MACHINE: WHAT'S THE DIFFERENCE?

Docker and virtual machines are two popular tools for deploying and managing applications. But what are the differences between these two technologies?

A virtual machine (VM) is an emulation of a specific computer system, allowing users to install multiple operating systems (OS) on a physical server or host.

All VMs are completely isolated from each other, which means changes made to one won't affect the others. Additionally, VMs can provide full hardware and operating system support for applications, making them ideal for larger projects that require specific configurations.

In comparison, Docker is a container-based technology that allows users to bundle an application and its dependencies into a single container image.

Unlike VMs, Docker containers share the same operating system kernel as the host system, reducing resource usage and providing more flexibility regarding hardware requirements.


HOW DOES DOCKER WORK?

Docker is a powerful and popular platform for running containerized software applications.

The software relies on Linux kernel functionality to provide its users with a virtual environment to develop, deploy and manage applications. With Docker, developers can create packages known as "containers" that contain all the necessary dependencies for an application to run independently and reliably on different operating systems.

Docker utilizes two key components of the Linux kernel – cGroups and namespaces – to achieve its goal of providing flexibility and independence.

cGroups limit the resources used by each container, ensuring that a container does not consume too many resources or affect other containers running simultaneously on the same server.

Namespaces isolate each container from one another so that they can run without interfering with or affecting other containers or processes running on the same machine.


KNOW THE DIFFERENCES BETWEEN DOCKER AND LINUX CONTAINERS

Containers have become a popular way to package and deploy applications. In the world of containers, two technologies stand out: Docker and Linux containers (LXC).

Both provide similar services – virtualization and lightweight resource management – but differ in important ways.

Docker technology is based on LXC but has been tweaked to make it easier to use and more flexible.

The platform was also designed with modern web development needs in mind, making it ideal for developers who need to rapidly build, deploy, and scale their applications.

Docker containers are self-contained environments that include everything an application needs to run successfully, from libraries and dependencies to configuration files.

On the other hand, traditional Linux containers (LXC) are more focused on system administration tasks like virtualizing servers or running multiple operating systems on one machine.


WHAT ARE THE ADVANTAGES OF DOCKER CONTAINERS?

Docker Containers can provide several benefits over traditional virtualization methods, such as improved scalability and resource consumption.

These advantages have made them the clear choice for many projects, from small-scale web applications to large, enterprise-grade architectures.

But after all, what are the advantages of Docker Containers? Check it out here.


1) LAYERS AND IMAGE VERSION CONTROL
 
Layers and image versioning are two essential concepts for operating Docker containers.

Docker containers use layers, which are a series of images or files that make up a single image. These layers can be used to quickly run or copy existing images and give users the ability to create new images with their own set of parameters.

One advantage of using layers is that it allows for quick and easy version control when creating images. This means that changes can be easily made to an existing image without having to start from scratch, allowing developers to quickly modify their work without having to redo all the configuration required for a complete container build.

Also, since layers are isolated from each other, any changes made to one layer will not affect another layer unless otherwise specified.


2) REVERSAL
 
The advantages of reverting to a previous version of Docker containers have become increasingly apparent to agile development teams.

Rollback is an essential part of the CI/CD pipeline and can be used to quickly identify, diagnose, and fix problems with applications.

When you revert to a previous version of Docker containers, it allows you to undo any changes you made or configurations that went wrong. The layers these different versions contain will help you track down any issues much faster, allowing your team to get back to working on the app instead of wasting time trying to find the root cause.

Having access to the layers also provides information about individual commits in each layer, guiding teams in identifying which components are causing problems in their software.


3) QUICK DEPLOYMENT

Rapid Deployment is a modern and efficient way to rapidly deploy new hardware.

With rapid deployment, the process of enabling new services can be as easy as creating a container for each service that needs to be deployed. By using Docker containers, companies can now launch multiple services in minutes instead of days or weeks.

The advantages of using Docker containers for rapid deployment are vast.

For example, a container can contain all the software components needed for a specific service, making the entire system easier to manage.

Additionally, deploying multiple services in this way allows companies to save time and money by reducing the labor costs associated with manually configuring individual servers or virtual machines.

Finally, with rapid deployment, you can also test new technologies without having to invest in additional hardware upfront, as you can always delete the container after testing is complete.

Kubernetes, commonly stylized as K8s, is an open source, portable, and extensible platform that automates the deployment, scaling, and management of containerized applications, making it easy to both declaratively configure and automate. It has a large and fast-growing ecosystem.

The name Kubernetes has a Greek origin and means helmsman or pilot . K8s is the abbreviation derived by replacing the eight letters "ubernete" with "8", becoming K"8"s .

Kubernetes was originally designed by Google which was one of the pioneers in the development of Linux container technology. Google has already publicly revealed that everything at the company runs in containers.

Today Kubernetes is maintained by the Cloud Native Computing Foundation.

Kubernetes works with a variety of containerization tools, including Docker.

Many cloud services offer a Service-based platform (PaaS or IaaS) where Kubernetes can be deployed under a managed service. Many vendors also provide their own brand of Kubernetes distribution.

But before we talk about containerized applications, let's go back in time a bit and see what these implementations looked like before.


HISTORY OF IMPLEMENTATIONS

Let's go back in time a bit to understand why Kubernetes is so important today.


TRADITIONAL IMPLEMENTATION

A few years ago, applications were running on physical servers and, therefore, it was not possible to define resource limits for applications on the same physical server, which caused resource allocation problems.


VIRTUALIZED DEPLOYMENT

To solve the problems of the physical server, the virtualization solution was implemented, which allowed the execution of several virtual machines (VMs) on a single CPU of a physical server. Virtualization allowed applications to be isolated between VMs, providing a higher level of security, as information from an application cannot be freely accessed by other applications.

With virtualization it was possible to improve the use of resources on a physical server, having better scalability since an application can be added or updated easily while achieving hardware cost reduction.


IMPLEMENTATION IN CONTAINERS

Containers are very similar to VMs, but one of the big differences is that they have flexible isolation properties to share the operating system (OS) between applications. So, they are considered lightweight.

Like the VM, a container has its own file system, CPU share, memory, process space, and more. Because they are separate from the underlying infrastructure, they are portable across clouds and operating system distributions.


CLUSTER IN KUBERNETES – WHAT ARE THEY?

As mentioned before, K8s is an open-source project that aims to orchestrate containers and automate application deployment. Kubernetes manages the clusters that contain the hosts that run Linux applications.

Clusters can include spanning hosts in on-premises, public, private, or hybrid clouds, so Kubernetes is the ideal platform for hosting cloud-native applications that require rapid scalability, such as streaming real-time data through Apache Kafka.

In Kubernetes, the state of the cluster is defined by the user, and it is up to the orchestration service to reach and maintain the desired state, within the limitations imposed by the user. We can understand Kubernetes as divided into two planes: the control plane, which performs the global orchestration of the system, and the data plane, where the containers reside.

If you want to group hosts running in Linux®(LXC) containers into clusters, Kubernetes helps you manage them easily and efficiently and at scale.

With Kubernetes, it eliminates many manual processes that an application in containers requires, facilitating and streamlining projects.


ADVANTAGES OF KUBERNETES

Using Kubernetes makes it easy to deploy and fully rely on a container-based infrastructure for production environments. As the purpose of Kubernetes is to completely automate operational tasks, you do the same tasks that other management systems or application platforms allow, but for your containers.

With Kubernetes, you can also build cloud-native apps as a runtime platform. Just use the Kubernetes standards, which are the necessary tools for the programmer to create container-based services and applications.

Here are other tips on what is possible with Kubernetes:

- Orchestrate containers across multiple hosts.

- Maximize the resources needed to run enterprise apps.

- Control and automate application updates and deployments.

- Enable and add storage to run stateful apps.

- Scale containerized applications and the corresponding resources quickly.

- Manage services more assertively so that the implementation of deployed applications always occurs as expected.

- Self-heal and health check apps by automating placement, restart, replication, and scaling.


Kubernetes relies on other open-source projects to develop this orchestrated work.

Here are some of the features:


- Registry using projects like Docker Registry.

- Network using projects like OpenvSwitch and edge routing.

- Telemetry using projects like Kibana and Hawkular.

- Security using projects like LDAP and SELinux with multi-tenancy layers.

- Automation with the addition of Ansible playbook for installation and cluster lifecycle management.

- Services using a vast catalog of popular app patterns.


KUBERNETES COMMON TERMS

Every technology has a specific language, and this makes life very difficult for developers. So, here are some of the more common terms in Kubernetes to help you understand better:

1) Control plane: set of processes that controls Kubernetes nodes. It is the source of all task assignments.

2) Node: they are the ones who carry out the tasks requested and assigned by the control plane.

3) Pod: A group of one or more containers deployed on a node. All containers in a pod have the same IP address, IPC, hostname, and other resources. Pods abstract networking and storage from the underlying container. This makes moving containers around the cluster easier.

4) Replication controller: he is the one who controls how many identical copies of a pod should run at a given location in the cluster.

5) Service: Decouples job definitions from pods. Kubernetes service proxies automatically receive requests to the right pod, no matter where it goes in the cluster or if it has been replaced.

6) Kubelet: is a service that runs on nodes, reads the container manifests, and starts and runs the defined containers.

7) Kubectl: The Kubernetes command-line configuration tool.


HOW DOES KUBERNETES WORK?

After we talk about the most used terms in Kubernetes, let's talk about how it works.

Cluster is the working Kubernetes deployment. The cluster is divided into two parts: the control plane and the node, with each node having its own physical or virtual Linux® environment. Nodes run pods that are made up of containers. The control plane is responsible for maintaining the desired state of the cluster. The computing machines run the applications and workloads.

Kubernetes runs on an operating system such as Red Hat® Enterprise Linux and interacts with container pods running on nodes.

The Kubernetes control plane accepts commands from an administrator (or DevOps team) and relays those instructions to the computing machines. This relay is performed in conjunction with various services to automatically decide which node is best suited for the task. Then, resources are allocated, and node pods assigned to fulfill the requested task.

The Kubernetes cluster state defines which applications or workloads will run, as well as the images they will use, the resources made available to them, and other configuration details.

Control over containers happens at a higher level which makes it more refined and without the need to micromanage each container or node separately. That is, you only need to configure Kubernetes and define the nodes, pods and containers present in them, as Kubernetes does all the orchestration of the containers by itself.

The Kubernetes runtime environment is chosen by the programmer. It can be bare-metal server, public cloud, virtual machines, and private and hybrid clouds. That is, Kubernetes works in many types of infrastructure.

We can also use Docker as a container runtime orchestrated by Kubernetes. When Kubernetes schedules a pod for a node, the kubelet on the node instructs Docker to start the specified containers. So, the kubelet collects the status of Docker containers and aggregates information in the control plane continuously. Docker then places the containers on that node and starts and stops them as normal.

The main difference when using Kubernetes with Docker is that an automated system requests Docker perform these tasks on all nodes of all containers, instead of the administrator making these requests manually.

Most on-premises Kubernetes deployments run on a virtual infrastructure, with an increasing number of deployments on bare-metal servers. In this way, Kubernetes works as a tool for managing the lifecycle and deployment of containerized applications.

That way you get more public cloud agility and on-premises simplicity to reduce developer headaches in IT operations. The cost-benefit is higher, as an additional hypervisor layer is not required to run the VMs. It has more development flexibility to deploy containers, serverless applications and Kubernetes VMs, scaling applications and infrastructures. And lastly, hybrid cloud extensibility with Kubernetes as the common layer across public clouds and on-premises.
