Now you can more easily operate your Azure Cosmos DB accounts at scale. Azure Cosmos DB fleet pools give you new capabilities when building multitenant software as a service (SaaS) applications.
You can simplify capacity management by creating a pool of throughput (RU/s) that can be shared by accounts in the fleet. You get all the security and performance isolation benefits of creating one Azure Cosmos DB account to represent a tenant or end customer, while also efficiently sharing RU/s resources across tenants to avoid overprovisioning at the per-tenant level. Throughput pooling is now generally available.
