Colocation Web Hosting Service allows the client to place their own server in someone else’s rack and share the bandwidth. Generally, it is more expensive than standard web hosting, but minuscule as compared to the bandwidth you would otherwise require at your place of work. You would either set up your own server in the provider’s rack or rent a server from them.
The provider supplies you with bandwidth, IP, and power to deploy the server. You would be able to access it just like a website on a hosting provider. However, here the server is yours, not theirs. There are several advantages of colocation web hosting service like bandwidth cost, better outage protection, additional security, etc.
A major disadvantage of colocation is the cost factor. This is also because you have to maintain and manage the server yourself. If the server needs to be upgraded, you would have to purchase the hardware and install it at your expense.
