Cloud Readiness Assessor Skill

Assesses application readiness for cloud migration, classifying applications using the 6Rs methodology and verifying cloud-native compliance.

Purpose

Enable cloud migration planning for:

• 6 Rs classification
• Cloud-native pattern compliance
• Stateless verification
• External dependency mapping
• Cost estimation

Capabilities

1. 6 Rs Classification

• Rehost (Lift and Shift)
• Replatform (Lift and Reshape)
• Repurchase (Replace/SaaS)
• Refactor (Re-architect)
• Retire (Decommission)
• Retain (Keep on-premises)

2. Cloud-Native Pattern Compliance

• Check twelve-factor compliance
• Verify statelessness
• Assess horizontal scalability
• Evaluate config externalization

3. Stateless Verification

• Identify session storage
• Find local file usage
• Detect in-memory caches
• Map persistent connections

4. External Dependency Mapping

• Map database connections
• Identify external APIs
• Find message queue usage
• Document service dependencies

5. Cost Estimation

• Estimate cloud compute costs
• Project storage costs
• Calculate data transfer
• Model reserved vs on-demand

6. Risk Assessment

• Identify migration blockers
• Assess complexity
• Evaluate downtime risk
• Document compliance concerns
