Service Resilience

CodeArts Check uses multi-active stateless cross-AZ deployment and inter-AZ data disaster recovery (DR) to enable service processes to be quickly started and recovered if a fault occurs, ensuring service reliability.

To achieve this, an isomorphic DR cluster is provided for CodeArts Check in a separate AZ. In the event of a natural disaster affecting the production cluster's location, the DR cluster can take over.

If the production cluster fails due to internal faults, it cannot handle read and write requests. In such cases, the DR cluster assumes the role of the production cluster.
