Service Resilience

COC provides a three-level reliability architecture and uses intra-AZ instance disaster recovery (DR), dual-AZ DR, and periodic backups to ensure service durability and reliability.

Reliability Solution

Brief

Intra-AZ instance DR

In a single AZ, COC implements instance DR in multi-instance mode and quickly rectifies faults to continuously provide services.

Multi-AZ DR

COC supports cross-AZ DR. If an AZ is faulty, COC services are not interrupted.

Data DR

Data is periodically backed up for data DR.
