Support for any of these operating systems typically depends on the level of management offered with a particular dedicated server plan. Operating system support may include updates to the core system in order to acquire the latest security fixes, patches, and system-wide vulnerability resolutions. Updates to core operating systems include kernel upgrades, service packs, application updates, and security patches that keep the server secure and safe. Operating system updates and support relieves the burden of server management from the dedicated server owner.
If you want top-of-the-line servers running a Linux operating system and plan on managing the network yourself, InMotion Hosting is a good option in the $100 ballpark. The company offers excellent support and exceptional server power. If you prefer to have your web host manage your servers for you, InMotion Hosting offers managed services, as well.
All of these features may look impressive, but if you don't know what Dedicated Hosting is in the first place, these features probably don't matter much to you at all. When you purchase a Dedicated Server from A2 Hosting, you are getting all of the resources listed with the server plan of your choice. You do not share these resources with any other user or customer. The bandwidth, RAM and data transfer are for your use exclusively. With all of these resources at your disposal, you can expect your hosting service to be both highly reliable with top performance.
