Systems and methods for cross-region data management in an active-active architecture

A system for cross-region data management in an active-active architecture, the system comprising:

• at least one cache service instance belonging to a first region;
• a first cross-region replication service (CRS) belonging to the first region;
• and
• a first cross-region synchronization service (CSS) belonging to the first region;
• the first CRS being configured to:
• receive a same-region key-value cache operation from the at least one cache service instance;
• and
• replicate the same-region key-value cache operation to a second CSS belonging to a second region;
• the first CSS being configured to:
• receive a cross-region cache key-value cache operation from a second CRS belonging to the second region;
• and
• replay the cross-region key-value cache operation to the at least one cache service instance;
• and
• the at least one cache service instance configured to execute a conflict-free replicated data type (CRDT) module to:
• receive cache data contained in the same-region key-value cache operation from a client of the first region or contained in the cross-region key-value cache operation from the first CSS;
• resolve any conflict between the cache data and existing entries in a cache database belonging to the first region;
• write the cache data to the cache database;
• and
• replicate the written cache data to the CRS.
