Many Amazon Web Services (AWS) customers want to migrate a large number of servers to the AWS Cloud as fast as possible, such as migrating 1,000 servers within 6 months.

As a team specializing in large migrations, we have learned a lot from our customers’ experiences. The aim of our content is to help you apply the correct strategy and best practices from the outset, applying lessons learned and streamlining your journey.
