MariaDB is fast, scalable and supports more storage engines than MySQL. Similar to MySQL, MariaDB supports external plugins, which means you can extend the database and apply it in more use cases, such as e-commerce, data warehousing and logging applications. MariaDB is both robust and scalable. It’s a drop-in replacement for the popular MySQL relational database, which means you can replace your MySQL server with a MariaDB one without changing the application code. Content management systems (CMS) are a key application of MariaDB. A CMS is a publication system through which web creators can push and manage large quantities of content on a website.
