Hybrid cloud ( #hybridcloud) strategies require planning. Specifically planning around the required SLAs for critical data, regulatory compliance and security. Data Center mainframe modernization efforts often call for reduction in costs associated with the data center and investment in tape. Mainframe data is not like user files. Lost, stolen, or ransomed data is not just inconvenient, it could lead to complete business failure. Although cloud is maturing and enabling business outcomes will require sharing of mainframe data on “open platforms”, critical data continues to require more control than standard distributed systems data.
