Colocation is defined as the services of a provider to offer its customers a computer center for their hosts are available. The hosting generally consist of server cabinets, or at least room to share, uninterrupted power, redundant air conditioning systems, access control, alarm and access to the Internet.
Under a Co-location refers to the rented room or space in a data center to house and operate their own hosting from there. Smaller providers often rent space from other providers, it) as a co-location.
Writing or creating content
A content provider (content provider) who may be, is of their own editorial content or content provided or providing an appropriate program (CMS) on a rental basis. It does not matter which provider will be hosted at the respective sites / domains. The contents are linked only by the content provider. Advantage of this option is that the user can use a CMS and not worry about your own server) must (support effort.
The dependence of the hosting is that the content is only available as long as long as the contractual relationship with the provider. Good content providers are not only rigid prefabricated templates available, but can make individual adjustments to each side, and these are upgradeable at any time.
Equipment and technical supplier
The ISP equipment form one or more autonomous networks (known also for Autonomous System) and have full control of the architecture, design and organization of their connections.
Connecting the ISP to the Internet
Unlike a customer who connects to the Internet via a service provider (the ISP), the provider conducts himself differently. In the general case, there is a link in the network, carrying its own data (for simplicity, the traffic of its subscribers), but also potentially other data operators.
The connection that connects two operators is fundamentally different from that which connects a subscriber to its ISP. The routers both operators will in fact exchange, not a single road (which boils down to “exit, this is where”) but hundreds of thousands of roads, including how to join all the other operators. Thus, when an operator is connected to 3 others, he learned from 3 different sources, all roads that each of these operators knew. He can then choose the path he deems most effective.
This mode of connection between operator, called the transit is generally charged (the largest to the smallest, most often). An alternative to this method of connection is on the same basic technique of exchanging a few roads (typically those leading to its own network). This is called peering (sharing between peers).
This process connection technology, significantly more complex than that used to connect a customer to his supplier, allows the operator to change at any time, peering agreements, or contracts in transit without significant impact to end users. An operator, even minor ones, usually has more transit contracts, and tens or even hundreds of peering.
