The ease at which I can set up clusters for any RDBMS is really great!The ability to have multiple instances running so we don't lose data if something goes wrong with an instance is also very helpful. For example, if our primary database fails due to hardware failure or power outage, we can quickly spin up another copy without having to worry about losing existing data.I wish there was more documentation available online. There are some things where it's not clear what certain options do or how they work together. We've been able to run several copies of Redis and MySQL off of each other quite easily and seamlessly.
