High availability (HA) is a core discipline in an IT infrastructure to keep your apps up and running, even after a partial or full site failure. The main purpose of high availability is to eliminate potential points of failures in an IT infrastructure.
IBM watsonx.governance as a Service on AWS is a highly available, multi-tenant, regional service. The service workload is distributed across multiple availability zones in a region. A single data center outage does not impact overall service availability. Data that is stored in watsonx.governance as a Service on AWS is replicated over the availability zones synchronously and is replicated to separate regions asynchronously.
In addition to synchronous data replication across zones in one region, the underlying relational database automatically takes a full snapshot backup daily and it is stored to regional S3 storage. The daily snapshot backup is kept for up to 35 days with transaction logs, which is used by the service instance restore operation with point-in-time data.
