Databases hold the crown jewels. Choose the right type and decide who operates it, then secure access, encryption and backups.

Types

Relational

Non-relational
Document, key-value, graph or wide-column stores (NoSQL) with flexible schemas and horizontal scale.

Deployment options

Self-managed
You install and run the database on VMs: full control, and you patch, back up and secure it.
Provider-managed
A managed database service handles patching, backups, replication and failover; you manage access, data and configuration.
