Timescale Cloud is a fully-managed, multi-cloud time-series database service that makes it easy to get started with TimescaleDB, allowing users to scale up or down and scale out via read replicas or database forks. It provides built-in high-availability, automated monitoring, automated backups, and point-in-time restore. To start using Timescale Cloud, users must first sign up for an account, create a new service, install psql, connect to the new database, and verify that TimescaleDB is installed. With these steps complete, users can now explore TimescaleDB with a sample dataset.
