Yes, AWS is similar with their DB offerings. You can discourage it from doing any updates/reboots (which causes a failover), but ultimately if they want to failover, they can at any time.

Ouch. If it knows it's about to fail over from an update, it really should get the follower totally in sync with the leader first.

HA on rds uses synchronous replication - you won’t lose data on automated failover under any normal circumstances.

Ok that's fine
