Azure Cloud Adoption Framework (CAF) - Azure Service Guide
What is Azure Cloud Adoption Framework?
The Azure Cloud Adoption Framework (CAF) is Microsoft’s official, structured methodology for planning, implementing, and governing cloud adoption on Azure.
It aligns business strategy, organizational readiness, and technical architecture into a repeatable, secure approach for migrating workloads or building new cloud-native solutions.
CAF breaks down cloud adoption into six stages:
- Strategy → Define business motivation for cloud adoption
- Plan → Assess current state and build an adoption roadmap
- Ready → Prepare the Azure landing zone and governance models
- Adopt → Migrate workloads or build new solutions
- Govern → Enforce compliance, security, and cost controls
- Manage → Operate, monitor, and continuously optimize
Simple Words Explanation:
Think of CAF as a step-by-step guide and toolbox that tells you how to move to the cloud the right way — from business planning, technical setup, migration execution, to ongoing governance and optimization.
Key Use Cases
- Data Center Exit: Migrate on-prem workloads to Azure with a structured plan.
- Application Modernization: Refactor legacy apps into cloud-native services.
- Governance Setup: Ensure compliance and security from the start.
- Hybrid/Multi-Cloud Governance: Manage resources across platforms with Azure Arc.
- Post-Merger IT Consolidation: Unify infrastructure after acquisitions.
Service Categories/Types
- Cloud readiness assessment framework
- Migration methodology
- Governance and compliance model
- Continuous operations and optimization guidance
