Virtual Machines
Virtual machines (VMs) are hardware-supported compartmentalizations of physical resources of a node. They run on a physical server, using its resources as separate, independently-operating computers.
VMs are widely used in cloud computing, enabling scalable, and on-demand computing resources. They provide a cost-effective way to run multiple operating systems and applications. VMs are managed by the owners themselves and offer the full flexibility and privilieges to software installation and congfiguration.
Virtual Machines are popular if your group needs to host externally accessible resources, custom software, or require Windows software.
| VM Size | vCPU | Memory | Disk | Cost per year |
|---|---|---|---|---|
| Small | 1 | 4GB | 100GB | $700 |
| Standard | 4 | 8GB | 250GB | $950 |
| Large | 8 | 16GB | 500GB | $1250 |
| XL | 16 | 32GB | 1000GB | $2100 |
Backup Policies
- Snapshots are taken at the VM host level, nightly
- Snapshots are saved on the back-end storage array which is resilient, but not redundant
- Snapshots are kept for 7 days
