Amazon RDS Multi-AZ deployment provides automated failover and increased availability for MySQL databases. In case of infrastructure failure or power outage in one Availability Zone, RDS automatically fails over to a standby replica in another AZ, minimizing downtime. This is the AWS-recommended way to achieve high availability for relational databases.
AWS Documentation Extract:
" Amazon RDS Multi-AZ deployments provide high availability, failover support, and data redundancy for database instances. In the event of infrastructure failure, Amazon RDS performs an automatic failover to the standby. "
(Source: Amazon RDS documentation, High Availability)
A: An ALB does not increase availability for a single database instance.
B: EC2 instance recovery does not move the instance across Availability Zones.
D: Termination protection prevents accidental deletion, not availability issues.
