Conclusion - AWS Prescriptive Guidance


Large-scale migrations present different challenges when compared to smaller-scale migrations. This is mostly due to the complexities introduced by the scale. For example, installing an agent onto a single server is fairly straightforward and will take approximately 5 minutes. However, if you have 5,000 servers in scope for your migration, this will take approximately 416 hours and will present the following challenges:

  • It’s likely that there are multiple operating systems that require different processes.

  • There might be separate Microsoft Active Directory domains to manage due to previous mergers and acquisitions.

  • Effective processes and tools are required to orchestrate the agent installation for each wave and then track and report the progress.

This strategy outlines large-scale migration best practices based on AWS Professional Services experiences helping a wide range of customers. This includes people, process, and technology perspectives. If you want to start or are in the process of migrating to AWS, consultants at AWS Professional Services would be happy to assist you.
