Abstract
Methods of and systems provide service redundancy between a master server and a slave server. The master server provides access to a pool of resources to a client. In response to detecting a fault on the master server, the master server is marked as disabled and services held on the master server are switched to the slave server and to a secondary pool of resources. The master service may be restarted if down. Then, provided that the master server is up, one or more tests are performed on the master server. The master server is marked as enabled if the tests are successful. The services may be switched back to the master server when the server is enabled. Services may further be rolled back to the slave server in case of an additional fault occurrence. The technique may also be used for updating a configuration in a service infrastructure.
