Cloud deployment has improved security and performance but still needs richer query features
MariaDB is easy to install. Performance of MariaDB has improved with the query optimizer. We use MariaDB's data-at-rest encryption. Encryption is available in MariaDB, so we are secure for transmitting data without concern about moving over networks. Query optimization in MariaDB is better than Oracle.
