|Cloud Servers||Dedicated Servers|
|Operating System||Dedicated Operating System;
Support dozens of operating systems
|Dedicated Operating System;
New hardware may not work well with old operating systems and device drivers.
|Software Applications||Server owners can remotely install and manage any compatible software application||Server owners can remotely install and manage any compatible software application|
|Administrative Access||Root access for Unix Servers. Administrative access for Windows Servers||Root access for Unix Servers. Administrative access for Windows Servers|
|Remote OS Install||Yes||No|
|Remote OS Reinstall||Yes||No|
|Remote Server Console Access||Yes||No|
|Remote Reboot a freezing Server||Yes||No|
|Server Snapshots||You can take a server snapshot first, then make changes to the server. If unexpected things happen after the change, a simple click of revert snapshot will get your server back to the original state.||No snapshot feature.|
|Server Performance||Perform better than low end or average dedicated servers.
See VMware Performance Benchmarks test scores.
|High end expensive dedicated servers perform better than most cloud servers.|
|Data redundancy||Dual parity disks (RAID 6) plus two hot standby disks||Lots of dedicated servers are on a single disk. Some dedicated servers are on a single parity disk (RAID 5) with no hot standby disk.|
|Server redundancy||If a physical server fails, HA enabled cloud servers will be automatically switched to other live physical servers.||If a dedicated server fails, you will need to build a new server, reinstall OS, and restore data from backups.|
|Power redundancy||Cloud servers run on a computing resource pool which is served by redundant power PDUs, redundant power UPSes, redundant power generators, and redundant power grids (not all data centers were built this way).||Most dedicated servers have a single power supply. Some dedicated servers have dual power supplies but they are on a single power PDU.|
|Hardware resource scaling||Can add CPU power and disk space while the server is running.||Have to shutdown the dedicated server and causing downtime when upgrading CPU or disk space.|
|Hardware upgrade||When upgrade to a newer more powerful server, no need to reinstall OS or devices drivers. The same cloud server can run on different hardware.||When upgrade to a newer more powerful server, need to reinstall OS and device drivers.|
|Disaster Recovery||If your cloud server fails and is unrecoverable, you can simply power on the cloud server backup image. Your cloud server will be back and running in a few minutes.||If your dedicated server fails and is unrecoverable, you will need to reinstall OS, restore files and databases from backups which can take many hours.|
|Costs||$29/month to $199/month.||$99/month to $1500/month.|
