Cloud Computing — Virtualization in Cloud Computing

Virtualization is a core technology behind cloud computing. It allows multiple virtual machines (VMs) to run on a single physical server, each acting as an independent computer. This makes resource management more efficient and cost-effective. Virtualization also enables scalability and isolation, meaning that each virtual machine is secure and separate from others. Hypervisors like VMware, KVM, and Hyper-V manage these virtual machines.

Types of virtualization include:

  • Server Virtualization: Running multiple virtual servers on one physical machine.
  • Storage Virtualization: Combining storage from different devices into a single pool.
  • Network Virtualization: Managing network resources virtually for better performance and security.
Example: A physical server can host 10 virtual machines, each running a different application or operating system.
