A Managed Cloud Database is a database service provided by a cloud platform where the provider handles installation, patching, backups, scaling, and high availability.
You focus only on using the database, not managing servers.
Cloud databases are mainly of two types:
SQL databases store data in tables with rows and columns and use structured queries.
NoSQL databases store data in flexible formats such as documents, key-value, wide-column, or graph.
You want to build an e-commerce application.

"view_time": "2026-01-08T10:30:00"
}
No server maintenance
Automatic backups
High availability
Secure access
Easy scaling
Managed cloud databases provide fully managed SQL and NoSQL solutions for modern applications.
They combine reliability, performance, and scalability without infrastructure management.
