High availability (HA)
The measure of a successful database solution is its availability. The architecture of IBM® Db2® Warehouse on Cloud features multiple tiers of reliability, which allows for fast, automated recovery from any issues that the data warehouse might encounter.
Compute HA
Any node failure is immediately detected by the cloud provider's container service. The containers and pods that were running in the failed node are scheduled to a new node from a pool of nodes. The system is back to 100% normal operation after a short downtime.
Storage HA
Db2 Warehouse on Cloud uses highly-reliable block storage, designed to provide consistent performance and protect data integrity and availability through maintenance events and unplanned failures. Storage is provisioned and managed independently of compute.
Network HA
Network connections are made highly available by provisioning your service with a redundant network interface card (NIC).
If the container service detects a network issue, pods and containers can automatically restart after a short downtime.
