Colocation hosting companies use purpose-built data centers to provide secure rack space and even caged areas for their business clients’ dedicated servers. Some business clients have 24/7 physical access to their own servers which are hosted in the colocation data center, while others choose to outsource day-to-day operations to the colocation company’s own engineers. Best-in-class colocation data centers have backup network connections and infrastructure, plus redundant power and cooling systems. Offsite data network storage and recovery between multiple datacenters are also options from some colocation providers.
