Abstract
A computing system includes a first storage unit at a first computing site. The first storage unit stores units of work data and data synchronously replicated from a first server cluster of a second computing site. The system further includes a second server cluster at the first computing site, the second server cluster is a proxy node of the first server cluster. The system further includes a second storage unit at the first computing site, the second storage unit stores the units of work data and data from the first storage unit asynchronously into the second storage unit. The system further includes a third server cluster at the first computing site, the third server cluster processes the units of work data asynchronously replicated into the second storage unit.
