Many businesses today choose to outsource hosting solutions rather than tackle the challenges of building the infrastructure themselves. Here's why:

Investment in state-of-the-art facilities and manpower/
Corporate IT departments must make a substantial amount of investment in state-of-the-art facilities and networks, that needs to be monitored and managed by experts 24 hours a day, 365 days a year. Such an investment of resources and personnel is an inefficient use of the enterprise's overall resources. Besides, it costs about 6 times more to build an in-house data center than it does to outsource.
Outsourcing your mission-critical Internet operations, not only saves you time but is also cost-efficient, and helps you to entrust your monitoring tasks to full-time experts.

Scalable Internet connectivity/
It takes too long to add capacity to an in-house site. With outsourcing, you can optimize your bandwidth utilization, and pay only for the bandwidth you need to use. This leads to an Internet connectivity that delivers scalability, high availability and the performance required by mission-critical Internet businesses.

Bandwidth availability/
A network with burstable bandwidth must be built to offer excess capacity at all times, to accommodate unexpected upswings in relation with site traffic volume. This kind of efficient scalability demands ongoing expert capacity planning, with specific dedication towards maintaining continuous headroom.
