  9. 9. First Pass Assessment Rapid Portfolio Assessment Cloud Native Application Inventory Business Priorities Inflight Migrations • Cloud Compatibility • Licensing Model • Compliance • Dependencies • Microservices architecture • “API- first” design • Built in fault Tolerance • Bundled metrics • Already virtualized x86 • Well-defined boundaries • Cloud licensing model • Known dependencies • Horizontally scalable • Leverages services • “12 factor” applications • Vendor cloud image • Hardware appliance • Non-x86 workload • Licensing Restrictions • On Premise dependency Eligible Friendly Not Cloud Now
