PlanetScale takes a multi-layered approach to ensure data safety by creating complete Vitess clusters whenever a database is created, which enhances the scalability and manageability of MySQL. The platform uses ACID compliance and semi-synchronous replication to guarantee the reliability and durability of databases, with backups and validation in place to protect against data loss due to application bugs or hardware failures. Additionally, PlanetScale features secure encryption at rest and in transit, automatic credential invalidation, and a strong security posture to safeguard sensitive information. The platform also offers safe migrations and revert functionality, allowing for instant undeployment of schema changes without data loss. By leveraging the maturity and battle-hardened code paths of MySQL and Vitess, PlanetScale provides a highly reliable database platform for businesses that depend on databases to store critical information.
