AWS re:Invent 2022 - Learn how Carrier migrated their global Oracle JDE landscape to AWS (ENT222)

Summary

Carrier, a Fortune 500 company, successfully migrated their JD Edwards (JDE) 9.2 from on-premises to AWS Cloud.
The project was led by Rick Carey from Carrier, with technical support from Jeremy Shearer, a senior partner architect at AWS.
Carrier's commitment to AWS included moving over 70% of their 4,000 servers and nearly 1,000 applications to AWS.
The migration involved six JDE instances, 16 data environments, and over 50 business units globally.
Over 3,000 test scenarios were completed, and more than 500 interfaces and integrations were migrated.
The project was completed in 10 months, moving approximately 2,000 business users seamlessly to the cloud.
Technical challenges included data compression, character set and case sensitivity issues, and Julian date formats.
Lessons learned from a previous migration in 2021 helped improve the process, including right-sizing infrastructure and cost management.
The success of the project was attributed to effective communication, cross-functional team involvement, executive support, and selecting experienced partners.

Carrier's migration to AWS was part of a strategic move to modernize and align with a Cloud First approach, emphasizing customer support and efficiency.
The decision to choose AWS over other cloud providers, including Oracle Cloud Infrastructure (OCI), was based on factors such as cost, scalability, performance, disaster recovery, and data movement.
The migration process involved significant data compression, achieving an 80% rate, which allowed for network transfer without additional AWS data transfer services.
Technical solutions included using SQL Server on EC2, leveraging AWS Database Migration Service, and optimizing instance types for JD Edwards workloads.
The project emphasized the importance of addressing technical debt, reducing run costs, and improving user experience.
Cultural, language, and localization considerations were critical, especially for global teams.
Organizational Change Management (OCM) played a significant role in ensuring user adoption and leveraging new tools and capabilities.
The partnership with AWS was crucial, with AWS providing honest feedback and cost-saving recommendations.
The experience underscores the viability of AWS as a cloud solution for JD Edwards and similar enterprise applications.
