Deployment of OceanBase Servers in the Public Cloud
Ant Financial’s ApsaraDB for OceanBase (OceanBase) is a fully native, distributed, relational database product that is completely controllable at the code layer. The public cloud OceanBase product is deployed on three copies in three different zones. The Paxos protocol ensures data consistency among multiple nodes in the event of a single point of failure or a single zone failure. It also ensures business continuity with a recovery point objective (RPO) of 0 and a recovery time objective (RTO) of less than 30 seconds, achieving high availability at the data center level. In the future, Alibaba Cloud will introduce a new version with five data centers across three regions to provide cross-city failover capabilities for high availability. OceanBase also supports highly flexible resource management. It also supports multi-tenant deployment. In OceanBase clusters, you can allocate instances as needed and scale online resources in or out.
