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
