When a company like myToys Group, which was born in an on-premises world, decided to move to Amazon Web Services (AWS), the primary motivation was scale and speed. The company chose to start with its highest-value application as a pilot project, but this approach may not be suitable for organizations without experienced team members. A generous buffer should be included in the timeline to account for unexpected delays. It's essential to measure customer impact by tracking conversion rates and using tools like New Relic to compare metrics between on-premises and AWS environments. Instrumenting everything early in the process can help identify issues, improve knowledge of services, and enhance planning. Finally, planning for post-migration product ownership is crucial to ensure operational excellence and knowledge retention within teams. By following these best practices, companies can successfully migrate to the cloud and achieve scalable infrastructure.
