CockroachDB Cloud addresses the need for scalability and cost-efficiency in globally distributed applications by offering three service tiers—Basic, Standard, and Advanced—each designed to balance flexibility, control, and cost through a multi-tenant architecture. The Basic and Standard tiers focus on affordability and ease of use, including a "free forever" option for small clusters, while the Advanced tier provides dedicated resources for larger enterprises. This multi-tenant approach allows for sub-second cold starts, automatic scaling to zero, multi-region operations, and strong workload isolation, ensuring consistent performance and resilience akin to distributed SQL systems. These capabilities, detailed in a research paper presented at SIGMOD 2025, have been integral to the CockroachDB Cloud production environment for over four years, enabling efficient and secure management of tenant clusters. Rebecca Taft, Director of SQL Engineering at Cockroach Labs, has been instrumental in developing the cost-based query optimizer and supporting features like geospatial indexing, drawing on her academic background from MIT and Yale.
