Effectively, as a virtual customer we are removed from the hardware cycle. If we retained the old cycle, every few years we were forced to evaluate a move to the latest hot box.

VPS (Virtual Private Servers) vs Physical Hosting vs Dedicated VM Hosting
VPS (Virtual Private Servers) are commonly confused with Dedicated VM Hosting, and while offering an affordable entry level to virtualised dedicated hosting, differ in many crutial areas.
This table allows you to easily and quickly compare your requirements against the pros and cons of virtualised and physical dedicated hosting infrastructure.

Detail
|
| High Availability |
Only available in clustered farms |
 |
 |
High platform availability with automatic hardware failover is built into the VMware-based virtualised environment |
| Managed Infrastructure |
Optional |
Partially* |
 |
The hardware underlying the virtualised infrastructure is monitored and managed the provider |
| Deployment |
Weeks/Months |
Hours/Days |
Hours/Days |
Physical infrastructure needs to be specified, ordered and delivered |
|
Dedicated Resources
(CPU, RAM)
|
 |
 |
 |
VMware ESX VI3 allows precise and accurate control over resource allocation, ensuring you receive what you pay for as a minimum |
| Dedicated Performance |
 |
 |
 |
VMware ESX VI3's precise resource control guarantees your performance cannot be impacted by other customers |
| Independence from underlying OS |
 |
 |
 |
Only the true virtualisation of VMware ESX VI3 allows complete independence from an underlying OS |
| Migration from existing hosting environment |
Non-trivial |
Possible* |
Fast & Efficient |
P2V (Physical to Virtualised) tools can be used to smooth the migration path |
| Upgrading Processor Speed |
Non-trivial |
Possible* |
Fast & Efficient |
Upgrading physical infrastructure requires specification, ordering and delivering and installation of any component.
This is a trivial change in a virtualised environment.

| Cloning |
 |
Possible* |
 |
Cloning a production environment for development purposes is easily delivered using virtualised dedicated hosting |
