  • Cloud deployment models: Public, Private, Hybrid, Multi-cloud
  • Shared responsibility model
  • Benefits of cloud: scalability, elasticity, agility, HA, fault tolerance, global reach
  • CapEx vs OpEx and the consumption-based model
Exam Tip: IaaS/PaaS/SaaS is always tested. Know real Azure examples: VMs = IaaS, Azure App Service = PaaS, Microsoft 365 = SaaS.

  • Azure regions, availability zones, region pairs, datacenters
  • Azure compute: VMs, AKS, Container Instances, App Service, Functions

  • Azure AI: Cognitive Services, Azure Machine Learning
  • Azure DevOps, GitHub Actions, Azure Arc
Exam Tip: This is the largest domain. Focus on knowing what each service does conceptually and which scenarios it fits. Availability Zones = physical datacenter isolation within a region.
