Abstract

A system for providing continuous availability comprises a second computing site that is geographically remote from a first computing site. The second computing site comprises a storage unit configured to store units of work data and data synchronously replicated from the first computing site. The second computing site further comprises a group of workloads configured to process the units of work data asynchronously replicated from the first computing site. The second computing site further comprises a software replication module configured not to replicate any data while the first computing site is available.
