Power redundancy, fire or flood protection, power cooling and physical security are all factors that need to be considered in running a stable hardware environment. Maintaining this type of environment can be extremely costly and require specific expertise in the field. Colocation services take these concerns away from the customer and allow them to focus on what is most important for their business.
Customers can also use colocation as a step toward cloud migration without relinquishing control of their physical hardware assets (such as physical servers) and maintain complete control over every aspect of their business systems. Changes can be made as and when it is required without having to rely on a third party service provider.
