Review and adapt it with qualified professionals before relying on it.
Problem Solved
Enterprises rush into "lift-and-shift" cloud migrations without assessing architectural readiness, resulting in runaway hosting bills, unmitigated latency bottlenecks, and migration rollbacks.
When to Use
- •Evaluating legacy on-premise application portfolios prior to major cloud migration initiatives
- •Classifying enterprise workloads according to the Gartner 6R dispositioning model
- •Assessing security, network, and organizational team skills readiness before cloud investments
When NOT to Use
- •For ongoing FinOps cloud bill optimization and reserved instance analysis (use TPL-FIN-004)
- •For single-service microservice API architecture design (use TPL-ARC-001)

Cloud Readiness Assessment - Worked Case Study
Fictional Entity: Enterprise Healthcare Network Cloud Adoption Readiness Assessment
Real-world production case study demonstrating complete operational adoption for Enterprise Healthcare Network Cloud Adoption Readiness Assessment.
- •Audited 240 enterprise applications establishing 6R dispositioning across 14 clinical and administrative domains
- •Identified 38 obsolete legacy applications slated for immediate retirement, saving $420,000 in annual data center hosting
- •Engineered 3-phase migration wave plan isolating HIPAA-regulated patient medical records in dedicated sovereign cloud VPCs
Frequently Asked Questions
What are Gartner's "6Rs" of cloud application migration?
The 6Rs represent the six strategic options for legacy workloads: Rehost (lift-and-shift to cloud VMs without modification), Replatform (move to managed cloud databases or containers without altering core code), Refactor (re-architect as cloud-native microservices), Repurchase (replace with SaaS), Retain (keep on-premise), and Retire (decommission unused systems).
What is the "double-bubble" cost phenomenon in cloud migrations?
The double-bubble refers to the period during an enterprise cloud migration when an organization must pay for their existing on-premise data centers, colocation facilities, and legacy hardware depreciation while simultaneously paying cloud consumption fees and migration consulting costs. Failing to model this 6 to 18-month financial overlap leads to severe budget overruns.
Why should a Cloud Center of Excellence (CCoE) be formed prior to migration?
A CCoE brings together architecture, security, network, finance, and operations leaders to establish centralized cloud governance, security guardrails, landing zone standards, and automated deployment pipelines before application teams begin deploying workloads, preventing chaotic and insecure cloud sprawl.
