Database as a Service is a database model where by a client or user accesses database resources over the cloud. It is a form of cloud computing where computing resources – in this case a database – is owned, controlled and managed over the cloud. One type of Database as a service model is the SQL data model. This is a fully-managed database service that makes it easy to set up, maintain, manage, and administer your relational databases on Cloud. This accelerate app development and make maintenance easy and productive using the SQL tools you love to use. Helps to take advantage of built-in intelligence that learns app patterns and adapts to maximize performance, reliability, and data protection. SQL Database scales on the fly with minimal downtime. SQL Database provides in-memory OLTP that improves throughput and latency on transactional processing workloads up to 30 times over traditional table and database. Some of the key capabilities include continuous learning of your unique app patterns, adaptive performance tuning, and automatic improvements to reliability and data protection, scaling as needed, with virtually no app downtime and management and monitoring of multitenant apps with isolation benefits of one-customer-per-database.
