Understanding a Cloud Adoption Framework
A Cloud Adoption Framework (CAF) is a structured methodology, published by major cloud providers, that guides an organization through the full lifecycle of adopting cloud at scale, from initial business strategy through migration execution to ongoing governance. Microsoft’s Cloud Adoption Framework for Azure and the AWS Cloud Adoption Framework are the two most widely referenced versions, and while their specific terminology differs, both aim to solve the same problem: giving business, security, and technical stakeholders a common roadmap and vocabulary instead of each team improvising its own approach to cloud adoption.
Typical Structure
Microsoft’s CAF organizes adoption into phases: Strategy (defining business justification and desired outcomes), Plan (aligning teams and creating a roadmap), Ready (preparing the environment, typically by building a landing zone), Adopt (covering both migration of existing workloads and innovation of new cloud-native ones), and Govern and Manage (ongoing operational and compliance oversight). The AWS Cloud Adoption Framework instead organizes guidance around six perspectives: Business, People, Governance, Platform, Security, and Operations, which map roughly to the same lifecycle stages but frame them around organizational capability areas rather than sequential phases.
Example Scenario
An enterprise adopting Microsoft’s CAF starts in the Strategy phase, documenting the business case for migrating a portfolio of legacy applications to reduce data center costs. In the Ready phase, it builds an Azure Landing Zone using Microsoft’s published Bicep or Terraform reference modules, establishing the subscription structure, networking, and policy guardrails. It then moves into the Adopt phase, executing the migration using Azure Migrate for straightforward rehosts while refactoring a handful of strategic applications into Azure-native services. Once workloads are live, the Govern and Manage phases take over as the ongoing operating model, feeding into the organization’s broader cloud governance program.
Why Organizations Use a CAF
A CAF gives disparate stakeholders, business sponsors who care about cost and timeline, security teams who care about compliance, and engineers who care about technical execution, a shared reference point instead of each operating from a different mental model of what “cloud adoption” means. It also reduces the risk of ad hoc, uncoordinated adoption, where individual teams each build their own inconsistent landing zones, governance approaches, and migration methods, leading to duplicated effort and security gaps.
Trade-offs and Limitations
Cloud Adoption Frameworks are comprehensive and can read as a long, prescriptive checklist; following every recommended step literally can slow down smaller organizations that don’t need the full enterprise-scale rigor the framework was designed for. Because AWS, Azure, and GCP each publish their own framework with different terminology and emphasis, organizations pursuing a genuine multi-cloud strategy can find the frameworks don’t map cleanly onto each other, requiring some translation or a vendor-neutral internal framework instead.
Best Practices
- Treat the CAF as a reference and checklist to adapt, not a rigid sequence that must be followed exactly regardless of organizational size or maturity.
- Use the framework’s “Ready” or “Platform” guidance as the direct input to building your landing zone, rather than designing one from scratch independently.
- Carry the “Govern” and “Manage” phases forward as an ongoing operating model, not a one-time step that ends once migration is complete.
- Establish a Cloud Center of Excellence as part of the “People” perspective to own the framework’s implementation and evolve it over time.
