Re: Elastic

All the tools are there to allow people to configure for full redundancy or for minimal cost and everything in between, its down to the customer to choose what's right for their workload - balancing the cost and complexity against the risk and impacts against their hosted services being down.

Those that have opted to configure using the standard redundant patterns will be OK as it will do the automatic failover as designed.

For those that went the minimal configuration and cost route, they accepted the impacts on resilience for their decision.

Its hardly fair to try and blame the vendor when its the customer that choses how to consume the service for their specific workload. The patterns for full resilience (and highest cost) are well publicised as are the ones patterns for cold standby backups and cloudformation to rebuild the same stack in other regions or zones. Read up on the AWS well architected framework

There is no need for full redundancy in one physical location and in fact its never possible to be fully redundant in one place due to a variety of reasons including forces of nature, even if you could fix all the technical issues around resilience.
