Azure Cosmos DB new shared database offer now available

Throughput provisioned at the database level now starts at 400 RU/s per database and can be shared across any or all containers within a database. Throughput can be scaled in increments of 100 RU/s. Provisioning throughput at the database level can result in savings for databases with multiple containers, versus provisioning throughput to each container individually.
