Resilience

LTS provides a three-level reliability architecture and uses intra-AZ instance disaster recovery (DR), dual-AZ DR, and multiple log data copies to ensure service durability and reliability.

Reliability Solution

Description

Intra-AZ instance DR

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

Multi-AZ DR

LTS supports cross-AZ DR. An AZ fault does not interrupt services.

Data DR

Data DR is implemented through log data replication.
