Colocation or co-located hosting is a type of hosting in which the privately-owned servers and networking equipment is housed in a third party data centre.
For the companies to ‘co-locate’ their equipment, have to rent space in a colocation centre.
With colocation the customer already owns the server and rents the required physical space to house it within a data centre instead of renting space on a server owned by a hosting provider unlike other kinds of hosting.
How does Co-location work?
There is a colocation provider that rents out space in a data centre where customers can install their equipment. But the provider also has to provide the power, bandwidth, IP address and cooling systems that the customers require for successful deployment of their server.
The colocation providers also offer high levels of security, including security guards and even biometric access control. Additionally, data centres also offer backups and UPS devices to secure against outages, including those caused by natural disaster, fire or flooding.
Racks and cabinets are used in order to rent the space. A rack is a standardised frame to mount the equipment and hardware, usually horizontally.
Advantages of colocation:
- Improved network security
- Better connectivity
- Redundant power supply
