Managed databases are cloud-based services that handle the setup, maintenance, and management of databases for users. This means that users do not need to worry about tasks like backups, updates, or scaling, as these are taken care of by the service provider. This allows businesses to focus on their applications and data without the overhead of database administration. These services often offer features such as automatic backups, security updates, and performance monitoring. Popular examples of managed databases include Amazon RDS, Google Cloud SQL, and Microsoft Azure SQL Database. By using managed databases, organizations can improve efficiency and reduce operational costs.
