CockroachDB, an open-source distributed SQL database, is designed to enable seamless scalability and high availability for businesses without the need for complex re-architectures. It operates with a shared-nothing architecture and employs the Raft consensus protocol to ensure data consistency and resilience against failures. The database can be deployed as the central OLTP component of an application's data architecture, evolving from a single-node proof-of-concept to a globally scaled service. Its geo-partitioning feature allows for fine-grained control over data replication, addressing issues of latency and data sovereignty essential for compliance with regulations like the EU's GDPR. CockroachDB's architecture facilitates zero-downtime upgrades and minimizes disruptions, making it suitable for enterprises that require rigorous service level agreements. Through an interactive D3 simulation, users can visualize the deployment stages and understand how CockroachDB supports the growth of businesses from local to global scales.
