Ask HN: What are the best SQL redundancy tool/services?

I have been researching the various SQL based DB options for a client's SAAS product that is now ready for redundancy and replication.

We're looking for a cloud service, want to avoid managing the servers in house.

We've been looking at Amazon Aurora, RDS Multi-AZ as well as Cockroach DB. I don't see very many alternatives... Any suggestions and reviews?
