DO databases have backups you can configure to your liking, store them on DO Spaces (like S3). DB user management is easy. There's also cache servers for Redis.
You can add a load balancer and connect it to your various web servers.
I think it took me about 30 min to setup 2x web servers, a DB server, cache server, load balancer, a storage server and connect them all as needed using a few simple forms. Can't really beat that.
