Best Practices – Technical
• Complex Proof of Concept (PoC)
• Maximum Automation
• Modernize Legacy Data Stores
• Workload-Based Modernization
• Define Tool-Evaluation Factors

20. © 2019, Amazon Web Services, Inc. or its Affiliates.
Best Practices – Business
• Vendor-neutral pattern selection
• Decide pattern, then tool, then architecture, then activities
• Serialize technical, then business-level modernizations
• Estimate modernization and runtime costs
• System integrators selection
