In this lesson
Prepare for the AZ-900 exam (Microsoft Azure Fundamentals). In this lesson: what cloud computing is, the shared responsibility model (what the provider always handles, what you always keep, and what shifts with IaaS, PaaS and SaaS), the three cloud models (public, private and hybrid), multicloud, Azure Arc and Azure VMware Solution, and how to choose a model. Includes three original practice questions.
Preview the topics
- A company moves all of its apps to Azure, some as virtual machines and some as software as a service. Which responsibility stays with the company in every case?
- A government agency wants computing resources used by that agency alone, on hardware it controls completely, in its own datacenter. Which cloud model fits?
- A retailer’s own servers handle normal traffic, but every holiday season it needs extra capacity for a few weeks, without buying new hardware. Which approach fits best?
