Resilience

AOM provides multiple reliability DR capabilities. Technical solutions (such as intra-AZ instance DR, cross-AZ DR, cross-cluster DR, and multiple data copies) ensure service durability and reliability.

Reliability Solution

Description

Intra-AZ instance DR

In a single AZ, multiple instances are used for DR. Faulty nodes can be quickly detected and remaining instances can still provide services.

Multi-AZ DR

AOM supports cross-AZ DR. When an AZ is abnormal, instances in other AZs can still provide services.

Cross-cluster DR

AOM supports cross-cluster DR. When one cluster is abnormal, AOM can continue to provide services.

Data DR

AOM configuration, metric, and alarm data is stored in multiple copies to ensure data reliability.
