Resilience

DMS for Kafka provides a three-level reliability architecture and uses cross-AZ DR, intra-AZ instance DR, and instance data replication to ensure service durability and reliability.

Table 1 Reliability architecture of DMS for Kafka

Reliability Solution

Description

Cross-AZ DR

DMS for Kafka provides cross-AZ instances that support cross-AZ DR. When an AZ is abnormal, the instances can still provide services.

Intra-AZ instance DR

A Kafka instance has multiple replicas for instance-level DR within an AZ. If the leader replica is faulty, another leader is quickly elected to ensure uninterrupted Kafka services.

Data DR

Data DR is implemented through data replication.
