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
