SYNCHRONIZING DATA ACROSS MULTIPLE INSTANCES OF AN APPLICATION IN A CLOUD

A method and system are provided for data synchronization. The method includes registering, in a database accessible by nodes in a cloud cluster system, node information for each node during an initialization of an application context for an application having at least one instance running on each node. The method further includes storing an update for data in (i) a local storage of a given one of the nodes and (ii) the database, responsive to a request to update the data received by the given one of the nodes. The method also includes generating a modified request that includes details for the updated data. The method additionally includes calling an application programming interface to update a state of respective local storages for the other nodes with the update responsive to the modified request, such that the update is synchronized across the at least one instance running on each node.
