Dedicated Hosting
™ Renting a server from a web hosting company.
™ Web hosting company is responsible for any problems that arise.
o Ex: Hard drive crashes or a CPU malfunctions.
™ It usually includes the necessary software to run your server.
o Ex: Software licensing costs, such as, the operating system and any server-based software you need.
Colocated Hosting
™ Buy your own server and pay the host to house it on their premises and connect it to the internet.
™ Same advantages as dedicated hosting – ultimate control over server.
™ You are in charge of hardware; therefore you are responsible for any maintenance that needs to be done.
™ You are also responsible for any software licensing costs such as the operating system and any server-based software you need.
™ One benefit = lower monthly costs.
™ Cost depends on how much space your server takes up.
™ Data centers normally house the servers in racks, which are then housed in cabinets.
o Cabinets = 40 rack units high
o Rack unit = 1.75
o Rack mounted servers = Measured in rack units
o 1U = 1.75
o Common Sizes = 1U, 2U, 4U
o Cost depends on how many units your server uses.
Decide whether the additional cost of dedicated hosting is worth the time and up front investment saved compared to collocated hosting.
If you have the resources to maintain a collocated server, and your resource requirements are high, collocation may be your best choice.
