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 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

Introduction The kernel is the core component of a Linux-based operating system, and it is responsible for managing the system's resources and communicating with hardware devices. Whenever a new version of a kernel is released, it typically includes important bug fixes, security patches, performance improvements, and other enhancements that can improve the overall functionality and stability of the system. However, when multiple versions of the kernel are installed on the same machine over time, they can take up valuable disk space and slow down system performance. Deleting old unused kernels is an essential maintenance task that helps keep your Linux-based ... Read More

An operating system is in charge of controlling a computer system's resources and acting as an interface between the hardware and software. The management of events that arise during the execution of programmes is a crucial component of operating system design. Traps and interrupts are two often utilised methods for this purpose. A trap is a computer-generated occurrence that results from an error or exception in the programme that is running at the time. Division by zero, page errors, and illegitimate instructions are a few examples of traps. The CPU instantly enters kernel mode after a trap occurs and ... Read More
