Updated: November 11, 2023

Cloud database engines are specialized software services provided by cloud service providers that allow users to store, retrieve, and manage data in the cloud. These engines are designed to handle the complexities of database management, including provisioning, scaling, replication, backups, and security, so that users can focus on developing applications and analyzing data without worrying about infrastructure maintenance. Cloud database engines come in various types, such as SQL databases for structured data, NoSQL databases for unstructured or semi-structured data, and in-memory databases for ultra-fast data processing. Examples of popular cloud database engines include Amazon RDS, Microsoft Azure SQL Database, Google Cloud SQL, and MongoDB Atlas. These services offer benefits like flexibility, scalability, high availability, and cost-effectiveness, making cloud database engines a vital component in modern cloud-based application development and data management strategies. Cloud Database Engines - database management systems that run on a cloud computing platforms with high load.
