Databases and platform freedom
CockroachDB is architected to give you the freedom to deploy your database anywhere, on any cloud. Use the best solution for your workloads and still gain value from any cloud provider.

Pick any (or multiple) providers and run self-deployed or as-a-service. Because no one should have to be locked into a single provider
