Topics in this course
Cloud models
Compare public, private and hybrid environments. Learn what you operate yourself in IaaS, PaaS and SaaS.
Azure services
Start with virtual machines, storage, databases and networking. Understand each service’s purpose rather than memorizing every feature.
Management
Subscriptions and resource groups help organize Azure resources. Monitoring lets you understand how resources behave.
Governance
Azure Policy helps evaluate or enforce rules; RBAC manages permissions; locks help protect resources from accidental changes.
Cost
Use estimates, budgets and cost monitoring. Actual bills depend on selected services, regions, configuration and usage.
