Dedicated Server Hosting

Dedicated server and colocation are technically the same. But, if dedicated server is equipment that belongs to a company and yopu rent it for your information, then colo is when you have your own server in datacenter of some company, where you rent a physical space for it, and not more - all management and repair has to be done by yourself, so it is only reasonable if you live close to the dc.

If you rent a dedicated server that owns the machine you just get access to a whole box, so if you cancel your contract payment or you will lose everything. With co-location must have its own box and pay for the space in the data center connections.
