Event-driven system failover and failback

A method for data center failover between a primary data center and a secondary data center, comprising:

• determining, by a system associated with the secondary data center, that a primary event processor, included in the primary data center, is associated with a failure,
• wherein the primary event processor is one of a plurality of primary event processors included in the primary data center and configured to process a plurality of first events stored in a main event store of the primary data center;
• identifying, by the system, a secondary event processor, in the secondary data center, that is to process one or more first events of the plurality of first events based on the failure,
• wherein the primary event processor and the secondary event processor are configured to process a same type of event;
• and
• causing, by the system and based on a configuration associated with the primary event processor or the secondary event processor, the one or more first events to be retrieved from one of the main event store or a replica event store for processing by the secondary event processor,
• wherein the replica event store is included in the secondary data center and is configured to mirror the main event store included in the primary data center.

A device for managing data center failover between a primary data center and a secondary data center, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, configured to:
• determine that a primary event processor, of a plurality of primary event processors included in the primary data center, is associated with a failure,
• wherein the plurality of primary event processors are configured to process a plurality of first events stored in a first main event store of the primary data center;
• identify, based on the failure, a secondary event processor, of a plurality of secondary event processors included in the secondary data center, that is to process one or more first events of the plurality of first events,
• wherein the plurality of secondary event processors are configured to process a plurality of second events stored in a second main event store of the secondary data center;
• identify a configuration associated with the primary event processor or the secondary event processor;
• and
• transmit an instruction to cause retrieval of the one or more first events, for processing by the secondary event processor, from one of the first main event store or a replica event store based on the configuration,
• wherein the replica event store is included in the secondary data center and is configured to mirror the first main event store included in the primary data center.
