Synchronization and replication in the context of mobile applications
... Replication is used to achieve better availability and performance by using multiple copies of a server system, where availability is the main goal. If one of the copies, or replicas is not running, the service which is provided by a set of replicas can still be working. It is also of great use if t ...
