IT infrastructure virtualisation
Virtualisation allows multiple virtual machines (VMs) to run on physical hosts. Consolidating suitable workloads can reduce hardware requirements, power consumption and cooling needs while making systems easier to manage.
The archived service focused on allocating CPU, memory, network and storage resources across VMs; monitoring infrastructure health; and preparing recovery procedures. Remote administration can reduce the need for on-site work. Whether upgrades can happen without downtime depends on the platform and architecture.
Resources and recovery
Supported platforms can adjust a running VM’s resources to meet demand. Snapshots provide a point-in-time state for suitable recovery operations, but they are not a substitute for independent backups.
Copies held on separate storage, on-site or off-site, support recovery and continuity planning. The original scope included:
- Disaster recovery.
- Clustering.
- Storage or network multipathing.
- Load balancing.
- VM snapshots and backup procedures.
- Business continuity.
Availability and application performance depend on the physical servers, storage, capacity planning and implementation—not simply on enabling virtualisation.
“Businesses implement virtualised infrastructure to remain competitive and benefit from it.”
