Dedicated servers, server colocation
Dedicated hosting means you're renting a server from a web hosting company. Your other choice is to buy your own server and pay the host to house it on their premises and connect it to the internet. This is what is known as colocated hosting.
Colocated hosting offers all the same advantages as dedicated hosting - you have ultimate control over your server. The extra benefit you get with colocated hosting is a lower monthly cost.
Mission-critical servers are stored in colocation facilities - which means, simply, that the heart of any business connectivity is housed within a colo. The quality of that business communications and functions, then, depend on the quality of the colo; any colo or data center has to be dependable and provide near-perfect uptime, and that breaks down into three things: reliable power, responsive network connections, and climate-controlled server rooms.
Colocation vs. Dedicated Server
This is the difference between dedicated servers and these solutions. The web hosting company owns a dedicated server. Colocation differs in that the you own the server.
Host Savings
To build and maintain the in-house requirements that your server demands can cost you valuable capital in facilities, Internet connectivity and maintenance personnel. Companies who offer these services already made the investment to provide these services so you can use your capital and time to focus on your core business.
Security
Most data centers provide you with collocated server confidence and the critical information contained on the server is safe. Data centers should be monitored 24-7. Your systems should be housed in a state-of-the-art data center, with redundant air cooling and filtering systems, designed to operate even in the event of a power failure. Data centers should be located and built to withstand natural disasters, and other emergencies.
