Server Virtualization
Server virtualization is a technology that partitions a physical server into multiple isolated virtual servers, each running its own operating system and applications. It uses a hypervisor (software layer) to abstract and manage hardware resources like CPU, memory, and storage, allowing multiple virtual machines (VMs) to operate independently on a single physical machine. This enables efficient resource utilization, improved scalability, and easier management of IT infrastructure.
Developers should learn server virtualization to optimize hardware usage, reduce costs, and enhance deployment flexibility in development and production environments. It is essential for creating isolated testing environments, running legacy applications on modern hardware, and building scalable cloud infrastructures. Use cases include server consolidation, disaster recovery, and DevOps practices like continuous integration and deployment.
