A high availability MySQL server on AWS is about the same difficulty as on your own kubernetes instance (I've got a play one on one of those $100 N100 machines, got one with 16G mem). Then:

    helm repo add mariadb-operator https://mariadb-operator.github.io/mariadb-operator
    helm install mariadb-operator mariadb-operator/mariadb-operator

And then you can just provision MariaDB "kind", ie. you kubectl apply with something specifying database name, maximum memory, type of high availability (single primary or multimaster) and secret reference and there you go: new database, ready to be plugged into other pods.
