CAF and WAF

Cloud Adoption Framework Steps

Strategy

Business justification & outcomes

  1. Motivations -> Why move? (migration, innovation)
  2. Success Measurements -> Savings/New markets/Revenue/...
  3. Business Justification -> ROI -> Business Case (Motivations + Measurements = Business Justification) -> MS Helpers: Azure TCO calc, Azure Pricing Calc, Azure Cost Management
  4. First Project:

  5. Business Criteria (Should already work (not WIP/Prototype/new Project), dedicated owner, strong motivation to move

  6. Technical Criteria (minimum dependencies)

Planning

CAF 1 Stage: Actionable plan

  1. Digital Estate (Asset Inventory) -> 5 Rs Rationalization:

  2. Rehost -> move to cloud without any changes (IaaS)

  3. Refaktor -> small changes to make it fit in Azure e.g. IaaS VM + Paas DB + PaaS Webserver
  4. Rearchict -> Introduce new technologies e.g. Key Vault, Backup Process, ...
  5. Rebuild -> Effort to do above is to high/not worth it -> start new
  6. Replace -> What does the cloud has to offer already -> Maybe Azure replaces your app with an SaaS solution

  7. Initial Organization Alignment (every one of relevance/importance needs to agree on moving to the cloud)

  8. Skills readiness plan -> review current skill set -> create plan to address gaps (new skills required)
  9. Cloud Adoption Plan = Digital Estate + Initial Organization Alignment + Skills readiness plan

Readiness

CAF 2 Stage: Prepare Azure Environment

  1. Azure Setup Guide -> Read Docs -> How do you want your environment to look like
  2. Azure Landing Zone -> Create Environment -> Code Base -> IaC
  3. Extend Landing Zone -> Expand for further cloud transition
  4. Check Best Practices -> Hard to change later, do it right

Adopt

CAF 3 Stage: Implement -> migrate & innovate

  1. Migrate

    • First Migration
    • Migration Szenarios (OS, App, Data, Other)
    • best practices -> tool check/design check/process check
    • migration process improvement -> eval current migration steps and improve where possible
  2. Innovate

    • Business Value Consensus -> Value/needs vs. cloud strategy
    • Innovation Guide -> MVP
    • best practices
    • process improvement

Overall Management Processes

Governance (overall process)

- comply, control and secure
- Define gouvernance solutions -> Business needs, agility, control risks

Management (overall process)

- Operate & Optimize
- Manage cloud environment (Cloud operations) -> Stability & Control Costs

Organize

- Roles and Responsiblites (RACI)
