Vail enables organizations to extend their data center into the public cloud and unifies on-prem and cloud storage into a single namespace. The data is available from one or multiple locations, allowing on-prem and cloud applications to use the same data without negatively impacting performance. When data is no longer needed in the public cloud, a golden copy can be maintained on-premises, and the data that is in the public cloud can be removed. Vail curates copies of your data and, through policy management, transfers the data to the optimal location for as long as needed.
