Virtualization allows a single physical server to be partitioned into multiple virtual servers so that each one appears as a dedicated server. Each virtual server runs its own operating system version (any version of Windows or Linux) and has its own hostname and IP address. Virtuals may be rebooted without affecting other virtual servers.
Virtual servers are usually sold on a per core, per Gig of ram and amount of storage used basis, thereby allowing you to control your costs and pay only for what you need, when you need it. Host virtual servers are usually clustered for high availability.
With a co-located server you can add-on the following services:
- Firewall security
- IPS/IDS protection
- System monitoring
- Backup with a variable retention period
- Software Licensing
- SSD Storage using SolidFire SAN with QoS
- Log monitoring
- PCI certification
