For many large enterprises, gathering data on your applications and developing a detailed business case for an all-in migration to AWS can be a time consuming activity. Instead of waiting on a full analysis to be completed, a global healthcare company decided to take a shortcut by reinventing the portfolio assessment process in a brilliantly simple manner. This new streamlined approach enabled them to immediately take advantage of the increased speed and innovative capabilities of AWS. In this session, IT directors and enterprise architects can learn these techniques to quickly identify which of their own applications fit cloud-friendly patterns; including, how to build a prioritized and multi-threaded migration queue that maximizes velocity and business value.

why they call it a shortcut!
If everyone knew about it, it would
just be called… “the way”.

20. Post-rehost cost reduction opportunities
• Stage 1: Rehost (Like-for-Like) (10-30%)
• Stage 2: Right-size Infrastructure based on Utilization (Prod, Test, Dev) (20-40%)
• Stage 3: Right-size Licensing based on Utilization (20-40%)
• Stage 4: Optimize Architecture for Cloud (10-30%)
• Stage 5: Operations Automation (auto-recovery, snapshots, etc.) (10-20%)
• Stage 6: Purchase AWS Reserved Instances (20-50%)
• Stage 7: Integrating Process Improvements (e.g. CI/CD, IaC) (20-30%)
• Stage n: AWS Innovations (-X%)

21. Calculated total cloud opportunity
Moderate - $17M savings over 5 years
Opportunistic - $37M savings over 3 years

22. Shortcut #2
Don’t plan for everything before doing something

23. Taking another look at our
application buckets…

24. Many of your existing commercial
software solutions across all buckets
have already been migrated to
the cloud for you.
You just need to repurchase them.
