MariaDB TX 2.0 extends MariaDB, the widely-adopted, open source database you know and love, with MariaDB Cluster, Galera clustering technology. MariaDB MaxScale offers connection- and statement-based load balancing. MariaDB TX 2.0 for Azure consists of a 3-node MariaDB Cluster and dual MariaDB MaxScale nodes in a Highly Available (HA) configuration.
If you are running MariaDB in a production environment, a MariaDB TX Subscription is recommended to provide access to management and monitoring tools, notification services for security alerts and bug fixes, technical and consultative support including 24x7 support coverage as well as performance tuning, best practice recommendations and code review — everything you need to confidently deploy MariaDB as part of your core infrastructure and in the cloud. The configuration of MariaDB MaxScale in this topology requires a MariaDB TX Subscription under the terms of the MariaDB Business Source License (BSL) for MaxScale if used in production.
