Introduction to virtualization (vmware)





Hello guys, in this post I will talk about virtualization "vmware" VMware is a virtualization and cloud computing software provider for x86-compatible computers VM stands for "Virtual Machine" (not to be confused with the broader term virtual machine), is a widely-installed operating system for IBM-compatible computers and servers that can host other operating systems in such a way that each operating system behaves as if it were installed on a self-contained computer with its own set of programs and hardware resources.
let us discuss the fundamental concepts of virtualization and review the VMware virtualization implementation options.

Following are few reasons why you might want to think about virtualization for your environment.

1:Run multiple operation systems on one server. For example, instead of having development-    server and QA-server, you can run both development and QA on a single server.
2:You can have multiple flavours of OS on one server. For example, you can run 2 Linux OS, 1    Windows OS on a single server.
3:Multiple OS running on the server shares the hardware resources among them. For example,  CPU, RAM, network devices are shared among development-server and QA-server running on the  same hardware.
4:Allocate hardware resources to different applications based on the utilization. For example, if you  have 8GB of RAM on the server, you can assign less RAM to one virtual machine (2GB to development-server) and more RAM (6GB to QA-server) to another virtual machine that is running  on that server.
5:High availability and business continuity. If VMware is implemented properly, you can migrate a  virtual machine from one server to another server quickly without any download.
6:This reduces the operational cost and power consumption. For example, instead of buying and  running two servers, you will be using only one server and run both development and QA on it.
