What this domain covers

What to know about Ensuring Successful Operation of a Cloud Solution

Cloud concepts questions usually test the service model (IaaS/PaaS/SaaS) and deployment model (public/private/hybrid/community) appropriate for a given scenario.

IaaS, PaaS and SaaS responsibilities and examples.

Public, private, hybrid and community cloud deployment models.

On-premises vs cloud trade-offs: cost, control, scalability.

How cloud connectivity options (VPN, Direct Connect, ExpressRoute) work.

Watch out for

Common Ensuring Successful Operation of a Cloud Solution exam traps

  • IaaS gives you infrastructure control; SaaS gives you only the application.
  • Hybrid cloud combines on-premises and public cloud — not two public clouds.
  • Cloud does not automatically mean cheaper or more secure.
  • Management responsibility shifts with each service model (IaaSPaaSSaaS).
