Abstract
Disaster recovery is provided for an application that is being hosted on a current data center, thus ensuring the availability of the application. An option for replicating session state data for the application is selected. This selection is made from a set of different session state data replication options each of which has different performance and resource cost trade-offs. The selected option determines how the session state data for the application is to be replicated. The selected option is implemented, where the implementation results in the session state data for the application being replicated outside of the current data center, thus ensuring that this data remains available in the event that the current data center goes offline.
