Understanding Virtualized Computing Environments
Virtualized computing environments have become a cornerstone of modern IT infrastructure. By abstracting physical hardware resources through software, virtualization allows multiple operating systems and applications to run on a single physical machine, optimizing resource utilization and reducing costs.
Types of Virtualization
- Hardware Virtualization: This involves creating virtual versions of physical hardware. Examples include virtual machines (VMs) using hypervisors like VMware and Hyper-V.
- Software Virtualization: This type includes virtualizing applications and operating systems. Containers, such as Docker, are a prime example.
- Network Virtualization: This abstracts network resources, allowing for the creation of virtual networks. Software-defined networking (SDN) is a common implementation.
