DBaaS
DBaaS is the Acronym for Database as a Service

A cloud computing model that provides managed database systems as an on-demand service. Instead of manually installing, configuring, and maintaining databases, organizations can use a DBaaS provider to handle provisioning, scaling, backups, updates, and security.
With DBaaS, users choose the database engine, storage size, and performance tier they need, while the service provider manages the underlying infrastructure. This approach dramatically reduces administrative overhead and enables developers to focus on building applications rather than managing data environments.
Most DBaaS platforms offer both SQL and NoSQL options, supporting relational databases such as PostgreSQL, MySQL, and SQL Server, as well as non-relational systems like MongoDB, Cassandra, and Redis. Leading examples include Amazon RDS, Google Cloud SQL, Azure Database, and MongoDB Atlas.
DBaaS simplifies data management, improves reliability through built-in redundancy and automated failover, and provides elastic scalability for modern applications that require high availability and performance.
