Virtualization and containerization essentials

“

Imagine you could make one physical computer act like an independent computers or package an application with everything it needs to run anywhere. And this is the power of two fundamental cloud technologies. One is virtualization, another is containerization. Let's start with the virtualization where the physical server runs the multiple virtual machines simultaneously. Each virtual machine acts like a complete computer with its own operating system, applications and resources. Think of it as dividing a powerful server into several smaller independent virtual servers. This is made possible by a special software layer called Hypervisor which manages and allocates the physical resources to each virtual machine. Now here is how virtualization works in practice. The hypervisor which sits directly on the physical server creates virtual versions of resources. For example, one single machine of 8 GB RAM converts it into 3 applications using virtual machines. And each virtual machine gets its…
