About ClearSky

For CoreSite customers, ClearSky® delivers on-demand primary storage, offsite backup and DR as a single service, and empowers enterprise IT teams with the flash performance of on-premises storage and the elasticity of the cloud.

Enterprises pay for a single, durable copy of their data and are able to access all data wherever it’s needed, on-prem or in the cloud, without ever needing to replicate it. That's right, no more making copies. The ClearSky service is fully elastic; pay for only what you use and scale up or down on-demand.

ClearSky Data’s service reduces traditional storage costs for customers by more than 50 percent and makes hybrid cloud easily attainable, so IT teams can run applications where they are best suited.

What ClearSky Data customers are saying:
