PlanetScale vs. Amazon RDS

PlanetScale and Amazon RDS are both managed MySQL database services with different architectures and features. PlanetScale is built on open-source Vitess technology, offering horizontal sharding, Git-like schema change workflows, automatic backup, recovery, advanced query analytics, and multi-region replication capabilities. It can be deployed on multiple cloud platforms like AWS and GCP. Amazon RDS supports several database engines, including MySQL, PostgreSQL, MariaDB, Oracle, and Microsoft SQL Server. It is designed to integrate well with other AWS native services. PlanetScale tends to be more cost-effective than many solutions due to its use of commodity-grade instance types optimally serving a user's unique workload. While both solutions are managed, RDS users often complain about having to manually manage database operations while PlanetScale is fully-managed.
