Understanding Key Cloud and Infrastructure Concepts

As technology continues to evolve, concepts like virtualization, scalability, agility, and high availability have become fundamental to modern IT infrastructure and cloud computing. Understanding these concepts helps individuals and organizations design systems that are efficient, reliable, and capable of supporting business growth. Let’s break them down in simple terms. What is Virtualization? Virtualization is the process of creating a virtual version of physical resources such as servers, storage devices, or operating systems. Instead of using one physical machine for a single task, virtualization allows multiple virtual machines to run on one physical system. This improves resource utilization, reduces hardware costs, and increases flexibility. For example, a company can run different applications on separate virtual servers while using only one physical server. Scalability Scalability refers to the ability of a system to handle increasing workloads by adding more resources. A scal
