More and more enterprise companies are migrating to the AWS Cloud and there are a number of reasons why. While every organization is going to have their own unique motivations, common drivers include exiting data centers, increasing business agility, improving workforce productivity, gaining transparency in operational costs and reducing risk. The AWS Migration Acceleration Program (MAP) is designed to help enterprises that are committed to a migration journey achieve a range of these business benefits by migrating existing workloads to Amazon Web Services. In this session, you will learn about proven migration patterns, methods and tools that AWS has delivered successfully to hundreds of enterprise customers globally that will help you accelerate migrations, reduce risk and quickly realize value.
