Serverless Database

"Azure SQL Database serverless is a new compute tier that optimizes price-performance and simplifies performance management for databases with intermittent, unpredictable usage. Serverless automatically scales compute for single databases based on workload demand and bills for compute used per second. Serverless databases automatically pause during inactive periods when only storage is billed and automatically resume when activity returns. Serverless helps users focus on building apps faster and more efficiently."
