Abstract
Methods and arrangements for managing a consistency group for computing sites. A plurality of computing sites contained within a consistency group are communicated with by using an aggregator, each of the plurality of computing sites comprising one or more of a virtual machine and a server. The aggregator acts as a central communication hub between the plurality of computing sites and combines data changes from the plurality of computing sites. Updates captured at each of the sites are received and the updates are batched. The updates are communicated, after the batching, to the plurality of computing sites, thereby ensuring data consistency across the plurality of sites. Other variants and embodiments are broadly contemplated herein.
