The short version

  • Only MariaDB has a free tier, so it costs nothing to try first.
  • Each has a real cost: Amazon RDS no super-user access or direct host connectivity limits advanced customization; MariaDB jSON support using text fields rather than native binary type; lacks MySQL's JSON syntax and functions
  • They diverge on capability: Amazon RDS covers Multiple DB Engines, MariaDB covers MySQL Compatibility.

Amazon RDS

  • No super-user access or direct host connectivity limits advanced customization
  • Pricing unpredictable and expensive compared to GCP alternatives with equivalent features

  • InnoDB tables limited to 1,017 columns and 64 secondary indexes
  • Transaction size limits in Galera (128K rows and 2GB by default)
  • Less strict SQL type checking than PostgreSQL; allows implicit conversions

Answered from the vendors’ own pages

Amazon RDS: What databases does Amazon RDS support?

Amazon RDS supports Amazon Aurora, PostgreSQL, MySQL, MariaDB, Oracle Database, and Microsoft SQL Server as managed database engines.

Source
MariaDB: Is MariaDB completely free and open source?

Yes. MariaDB Server is licensed under GPLv2 and guaranteed to remain perpetually free and open source, independent of any commercial entities.

Source
Amazon RDS: Does Amazon RDS handle backups automatically?

Yes. Amazon RDS automates backup configuration, backing up your database and transaction logs. Blue/Green Deployments allow safer updates by mirroring production in staging before applying changes.

Source
MariaDB: Is MariaDB backward compatible with MySQL?

Yes. MariaDB was designed as a drop-in replacement for MySQL. Every application, driver, and configuration that worked with MySQL works with MariaDB without code changes.

Source
Amazon RDS: How does Amazon RDS Proxy improve performance?

Amazon RDS Proxy is a managed database proxy that makes applications more scalable by reducing database connection overhead, more resilient to database failures, and more secure through built-in authentication.

Source
MariaDB: What are the storage engine options in MariaDB?

MariaDB supports multiple storage engines including InnoDB (transactional, default), Aria (crash-safe, good for read-heavy workloads), and MyISAM. The Aria engine is faster than InnoDB for certain read-heavy queries and full table scans.

Source
Amazon RDS: Does Amazon RDS provide read replicas?

Yes. Amazon RDS supports read replicas across availability zones and regions, enabling horizontal scaling of read capacity while maintaining a single write primary.

Source
MariaDB: How much does MariaDB cost?

MariaDB Community Server is completely free to download and use. MariaDB offers paid enterprise support and managed cloud services for organizations needing professional support.

Source
Amazon RDS: Can I access the host directly via SSH or Remote Desktop?

No. Amazon RDS does not allow direct host access via SSH, Telnet, or Windows Remote Desktop Connection. Database access is limited to database clients and management console.

Source
MariaDB: Does MariaDB support native JSON storage?

MariaDB stores JSON using text fields (the JSON type is an alias for LONGTEXT), not as a native binary type like MySQL does. JSON support exists but is less sophisticated than MySQL's JSON functions and syntax.

Source
MariaDB: What scaling options does MariaDB provide?

MariaDB supports both scaling up (more cores, memory, storage) and scaling out (read replication, Galera Cluster with multi-node replication). However, Galera Cluster performance cannot exceed the slowest node in the cluster.
