AWS Cloud Migration Guide: Methodology for migration readiness and cloud adoption

Editor’s note: This guide has been deprecated. We recommend you check out Public Sector Cloud Transformation: An AWS how-to guide instead.


There are many reasons why public sector customers are migrating to the cloud. Some are migrating to increase the productivity of their workforce. Others are looking to consolidate data centers or minimize costly infrastructure sprawl and modernize legacy applications that have lost value over time. Additionally, visionary organizations are re-imagining their missions by upgrading to cloud-hosted technologies that drive digital transformation.

Developing and executing your cloud transformation can be intimidating, even to experienced IT leaders. Having a clear understanding of existing infrastructure costs and the details of your unique migration use case will help you calculate projected ROI.

Drawing from years of best practices and customer conversations, we’ve packaged these learnings into our new AWS Cloud Migration Guide.

  • Have you clearly defined the scope and the business case for the migration?
  • Have you evaluated the environment and applications in scope through the lenses of the AWS CAF?
  • Is your virtual private cloud (VPC) secure, and can it act as a landing zone for all applications in scope? A virtual private cloud (VPC) is a virtual network dedicated to your AWS account. It is logically isolated from other virtual networks in the AWS Cloud. You can launch your AWS resources, such as Amazon EC2 instances, into your VPC.
  • Have your operations and employee’s skills been reviewed and updated to accommodate the change?
  • Do you (or does a partner) have the experience necessary to move the tech stacks that are in scope?

AWS provides a variety of tools to help create your business case for migration. The AWS Simple Monthly Calculator provides directional business case inputs, while the AWS Total Cost of Operation (TCO) calculator supports your refined business case. Additionally, AWS has tools to help you with cost estimation.
