Database-as-a-Service (DBaaS)

Definition:

Database-as-a-Service (DBaaS) is a cloud-based service model where a third-party provider hosts, manages, and maintains database infrastructure, allowing users to access and use databases without handling the underlying hardware, software, or administration tasks.

In simple terms: Instead of building and maintaining your own database server (like owning a house), you rent database services from a provider (like staying in a hotel).

How It Works

graph LR
    A[Your Application] --> B[Internet] --> C[DBaaS Provider] --> D[Managed Database]
    E[Automatic Backups] --> C
    F[Security Updates] --> C
    G[Scaling] --> C

Example:

Amazon RDS

• What: Managed relational databases (MySQL, PostgreSQL, etc.)
• You get: Database without server management
• Provider handles: Backups, updates, scaling, security
