VPS VS Dedicated Servers
12 January 2007We are considering many issues about Virtual Private Servers (VPS) and Dedicated Servers. Among those issues there are : power consumption, software backups, maintenance costs, network equipment, performances and software licensing.
VPSs(Virtual Private Servers) have higher hardware utilization rate.
They are cheaper since they have less power electricity costs than physical servers.
Maintenance of VPS is more expensive, since administrators needs more knowledge for administration VPS related technologies like Xen, Virtuozzo or OpenVZ. Moreover, all maintenance on many systems they must perform in short amount of time.
Security is more complex in VPS than in dedicated servers. There are two layers of security : physical server security and VPS based security. VPS monitoring is more difficult than monitoring dedicated servers.
VPS needs usually more expensive drivers like multi-port network adapters and other related equipment like UTP cables and switches.
VPS providers usually need more IP addresses than providers of dedicated servers. If one has 100 physical computers with 20 VPS on each it is still 2000 IP addresses. Physical system which runs many VPS might have very high packets per second (PPS) in network.
There are sometimes advantages in software license with having VPS.
VPS nowadays have usually very little overhead (less than 5%) on some modern virtualization software. But, disk I/O performances might be slow due to more disk fragmentation and number of different request at the same time. At the another way, if VPS provider use RAID5 or other controllers, in case of peak use, VPS might have much better hard disk performance than average dedicated server.
