A Managed Database is a cloud-based service where a provider takes care of the setup, maintenance, and management of a database. This allows users to focus on their applications without worrying about the underlying infrastructure. The provider handles tasks like backups, updates, and security, ensuring that the database runs smoothly and efficiently. Using a managed database can save time and resources for businesses. It typically offers scalability, meaning it can grow with the needs of the organization. Popular examples of managed database services include Amazon RDS, Google Cloud SQL, and Microsoft Azure SQL Database.
