Title

AWS re:Invent 2023 - Completing a large-scale migration and modernization with AWS (ENT215)

Summary

Jonathan Allen and Oscar Valladares discuss strategies for large-scale migration and modernization on AWS.
They emphasize the importance of leadership, understanding the "why" behind migration, and having a clear business case.
AWS offers various services and tools to facilitate migration, such as Migration Evaluator, AWS Migration Acceleration Program (MAP), and AWS Mainframe Modernization Service.
Modernization drivers include developer efficiency, automation, security, visibility, and tooling consistency.
The session covers the "6 Rs" of migration strategies: Rehost, Relocate, Repurchase, Refactor, Retire, and Retain.
They introduce new patterns like event decoupling, strangler pattern, domain-driven design, and generative AI for modernization.
Data migration is a critical aspect, with tools like AWS DataSync and Database Migration Service (DMS) to assist in the process.
The session concludes with the importance of executive commitment, a solid business case, and investing in teams for successful migration and modernization.

AWS continues to invest in tools and services to automate and simplify the migration and modernization process for customers.
The adoption of containers, serverless architectures, and generative AI is becoming increasingly popular among AWS customers looking to modernize their applications.
Security, reliability, and durability are non-negotiable aspects of migration and should not be compromised for the sake of speed or convenience.
AWS's partnership with various vendors and the acquisition of companies like Blue Edge indicate a commitment to providing comprehensive solutions for mainframe modernization.
The AWS Migration Acceleration Program (MAP) is a holistic approach that includes methodology, tools, services, partners, training, certification, and incentive investment programs to support customers' migration journeys.
The session highlights the importance of executive sponsorship and team enablement as critical factors for successful cloud migration and modernization initiatives.
