In Infrastructure as a Service (IaaS), the provider gives you raw compute, storage, and networking. You install, configure, and run your own database. This means database roles—the sets of permissions defining what a user or service can do—are fully under your control. Unlike PaaS systems where many permissions are abstracted, IaaS requires you to design, create, and manage these roles directly.
Core Role Types in IaaS Databases
IaaS database roles usually align to standard permission patterns:
- Administrator Roles – Full control over the database instance, schema, security settings, and OS-level integration. Often limited to a small number of trusted operators.
- Developer Roles – Create and modify schema, run queries, manage stored procedures. No access to certain security or system-level functions.
- Read-Only Roles – Fetch and view data without altering schema or records. Used for analytics, reporting, and auditing.
- Service Roles – Scoped to specific applications or services, granting minimal rights needed for operation. Often tied to automation and CI/CD pipelines.
Why Role Design Matters
In IaaS, you are responsible for securing the database from unauthorized access, misconfigurations, and privilege escalation. Poorly defined roles lead to excessive permissions, creating single points of failure. Precise role-based access control (RBAC) streamlines onboarding, reduces blast radius, and meets compliance requirements.
