3 Cloud Migration - Coggle Diagram

- - - - Identify First App for mIgration
        
        Business Value
        
        Medium business value
        
        Team
        
        High performance team, Cloud, DevOps, SRE
        
        Dependencies and Refactoring
        
        1. Statelesss App
        2. Only Configuration change
        3. Rehost (Lift and Shift)
        4. No huge data
        
        Pick a representative App
        
        No Specialized Requirement
        (Regulation, Compliance, License, Infra)
        
        Batch process is a good candidate
  - - - License
        
        License is valid to run the Application in the cloud
      - Regulation and Compliance
      - Infra
        
        No need of specific hardware
    - - 2a) Applications
        
        This may be Graph
        (cyclic dependency).
        
        Refactor Apps to make Graph to Tree Structure
        
        Move Read operations (Micro-services) to Cloud
        and later move CUD operations.
      - 2b) Data
        
        Data Spaghetti - Data is being operated (CRUD)
        across many applications
        
        Domain Driven Design
        (Explicit ownership of data (/tables) with a single App)
  - - - Define Resource hierarchy (Access control)
- - - - build new cloud capabilities
  - - - Operational change management
- - - - Preemptible VMs
    - - Coldline storage
      - For SPII data => IAM, Encryption, DLP
    - - Performance tests, Integration tests, System tests
