This document summarizes a presentation given at an AWS Summit on moving IT to the cloud. It discusses how moving to AWS can make IT more cost effective and reliable. However, it notes that having a clear strategy and understanding requirements is important to avoid issues. A case study is presented where loose requirements for a website project led to an inadequate initial AWS design that did not meet the client's needs. The key lessons are that accurate business requirements, a well-defined strategy, and a detailed technical design are needed to fully benefit from moving to AWS.
