Virtualisointialustoissa

Virtualisointialustoissa, commonly referred to as virtualization platforms, are software systems that enable the creation and management of virtual machines (VMs). These platforms abstract the underlying physical hardware, allowing multiple operating systems and applications to run concurrently on a single server. This abstraction is key to their functionality, providing a layer between the physical resources and the virtualized environments.

The primary benefit of virtualization platforms is enhanced resource utilization. Instead of dedicating an entire physical server to a single application or operating system, multiple VMs can share the same hardware, leading to reduced costs for hardware, power, and cooling. They also improve flexibility and agility. New servers can be provisioned in minutes rather than days or weeks, and VMs can be easily moved, backed up, or replicated.

Common examples of virtualization platforms include VMware vSphere, Microsoft Hyper-V, and KVM (Kernel-based Virtual Machine). Each platform offers a suite of tools for managing VMs, including creation, configuration, monitoring, and migration. Security is also a significant consideration, with platforms implementing features to isolate VMs from each other and from the host system. Disaster recovery and business continuity are further advantages, as VMs can be easily backed up and restored, minimizing downtime in case of hardware failure or other disruptions.
