Amazon RDS vs PlanetScaleDB: What are the differences?

Developers describe Amazon RDS as "Set up, operate, and scale a relational database in the cloud". Amazon RDS gives you access to the capabilities of a familiar MySQL, Oracle or Microsoft SQL Server database engine. This means that the code, applications, and tools you already use today with your existing databases can be used with Amazon RDS. Amazon RDS automatically patches the database software and backs up your database, storing the backups for a user-defined retention period and enabling point-in-time recovery. You benefit from the flexibility of being able to scale the compute resources or storage capacity associated with your Database Instance (DB Instance) via a single API call. On the other hand, PlanetScaleDB is detailed as "A fully managed cloud native database-as-a-service". It is a fully managed cloud native database-as-a-service built on Vitess and Kubernetes. Effortlessly deploy, manage, and monitor your databases in multiple regions and across cloud providers.

Amazon RDS and PlanetScaleDB belong to "SQL Database as a Service" category of the tech stack.

Some of the features offered by Amazon RDS are:

• Pre-configured Parameters
• Monitoring and Metrics
• Automatic Software Patching

On the other hand, PlanetScaleDB provides the following key features:

• Cloud-native database
• No More “Query of Death”
• No Vendor Lock-In
