Second, the new Cassandra API support brings the flexibility to use the data model and API of their choice. And the Reserved Capacity option enables customers to get up to 65 percent off the cost of their Cosmos DB usage.
Microsoft today also announced the new Azure SQL DB hyper scale service tier that adapts to workload needs. It can auto-scale up to 100 TB per database.
