Overview Nginx is a popular open-source web server that has been widely used for its high performance, scalability, and reliability. It is also commonly used as a load balancer and reverse proxy server. On the other hand, Kubernetes is an open-source container orchestration platform that automates the deployment, scaling, and management of containerized applications. It provides a flexible architecture that can run on-premises or in the cloud. Nginx has become an essential component for many organizations that need to deploy their applications at scale. Pre-requisites Understanding of Kubernetes architecture and concepts Before deploying Nginx on a Kubernetes cluster, it is ... Read More
Introduction Virtual machines (VMs) are a powerful tool for creating and managing multiple operating systems on a single physical machine. They allow you to run different operating systems, applications, and services without the need for additional hardware. Instead of having multiple physical computers with their own dedicated resources, VMs share the resources of the host machine. Through this sharing of resources, VMs enable you to create isolated environments that can simulate different computing scenarios or test new software and applications without interfering with other processes. Setting up the Environment Installing KVM on the Host Machine Before deploying multiple virtual machines, ... Read More
Introduction HTML5 is the fifth and latest version of Hypertext Markup Language, which is the standard language used for creating web pages and applications. Unlike its predecessors, HTML5 offers a more efficient way of coding websites, making it easier for developers to create rich and interactive content. With HTML5, developers can use new tags like video and audio to include multimedia elements on their web pages without relying on third-party plugins. The canvas tag allows developers to create animations and graphics directly on a web page using JavaScript. Additionally, HTML5 provides better support for mobile devices by introducing responsive ... Read More
In today's world, data is the lifeblood of businesses. Whether it is customer data, sales data, or product data, the ability to store, search, and analyze it effectively can make a significant difference in a company's success. Elasticsearch is a distributed search and analytics engine designed for speed and scalability. It can process millions of queries per second and handle petabytes of data with ease. Kubernetes, on the other hand, is an open-source container orchestration system that automates application deployment, scaling, and management. Setting up the Environment Installing the Necessary Tools (kubectl, helm) Before deploying Elasticsearch on Kubernetes, ... Read More
Introduction Data-center deployment involves the process of setting up computer systems and related components such as storage, networking, and software applications to support the running of business operations. It is critical for organizations to have a reliable, scalable, and secure data-center infrastructure to ensure continuity in their daily operations. Red Hat Enterprise Virtualization (RHEV) environment provides a robust platform for managing data-center resources efficiently. RHEV Environment uses Kernel-based Virtual Machine (KVM) hypervisor technology which provides virtualization services that allow multiple Operating Systems (OS) to run on the same physical machine without interfering with each other. The RHEV environment also ... Read More
Redis is an open-source, in-memory data structure store that can be used as a database, cache, or message broker. It is known for its high-performance and low-latency capabilities, making it a popular choice for real-time applications. On the other hand, Docker is a containerization platform that allows developers to package applications into containers that can run anywhere on any platform. Containers are lightweight, fast to deploy and have small footprints compared to traditional virtual machines. Preparing for Deployment Installing Docker on your machine Before you can deploy Redis in Docker, you'll need to install Docker on your machine. ... Read More
Introduction MongoDB is a popular, open-source NoSQL database that is designed to store and manage unstructured data. It provides high performance, scalability, and flexibility for modern applications. On the other hand, Docker is a containerization platform that enables developers to package their applications and dependencies into portable containers that can run consistently across different environments. It simplifies the software delivery process by providing a lightweight, isolated runtime environment for applications. Setting up the Environment Installing Docker on the local machine Before setting up MongoDB, it's important to install Docker on your local machine. Docker is a containerization platform ...

Introduction When it comes to cloud computing, there are two primary options: virtualized servers and bare metal servers. A virtual server runs on top of a hypervisor, which is essentially a layer of software that sits between the physical hardware and the operating system. In contrast, a bare metal server runs directly on the physical hardware without any intervening layers. A bare metal cloud server combines the benefits of both models. It provides dedicated hardware resources like a traditional bare metal server, but it's provisioned and managed through an API or web interface like a virtual server in ... Read More
Django has revolutionized web engineering, making it accessible and streamlined for developers globally. Its notable characteristic is the robust form manipulation system, which simplifies the development of web forms while also facilitating their verification and handling with ease. Concentrating on displaying these forms as HTML lists offers users a multitude of perks, such as advanced styling possibilities due to easy customization capabilities as well as augmented responsiveness and amplified accessibility. This composition plunges into the nuances of effectively displaying Django forms as lists by illuminating their numerous boons, delineating straightforward steps for implementation, and offering best practices for the ultimate ...

Introduction Linux is an open-source operating system, which is favored by many users for its robustness, flexibility and stability. One of the key features of Linux is its ability to provide users with better control over their system's resources. This is achieved through the use of the partitioning scheme, which divides a hard drive into multiple sections or partitions, allowing for more efficient use of space and resources. What a partition is in Linux? A partition in Linux can be thought of as a logical division or section on a hard drive that isolates data from other parts on ... Read More
