ClearDB vs PlanetScaleDB: What are the differences?

Developers describe ClearDB as "Fault tolerant database-as-a-service in the cloud for your MySQL powered applications". ClearDB uses a combination of advanced replication techniques, advanced cluster technology, and layered web services to provide you with a MySQL database that is "smarter" than usual. 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.

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

Some of the features offered by ClearDB are:

• Global Multi-Master Design- ClearDB uses geo-distributed MySQL database configurations for the ultimate in database availability, survivability, and performance. Even if whole cloud regions go offline, your database will stay online.
