A Successful Transition to AWS Cloud for
Introduction
In the dynamic landscape of technology, legacy systems can pose significant challenges for large enterprises. This case study delves into the intricacies of a mainframe modernization project undertaken by the LMTEQ team for our client who is a renowned global manufacturing leader—a Fortune 500 giant with a robust presence in the automotive industry.
Objective
-
Our client aimed to migrate its legacy applications, hosted on a mainframe system, to the AWS Cloud. This ambitious undertaking by our team involved modernizing applications catering to diverse business functions across the USA, Canada, Europe, and Asia.
-
The primary goal was to enhance operational efficiency, improve user experience, and leverage the benefits of cloud-based technologies.
Challenges and Pain Points
Onboarding & Access
The onboarding process presented a multifaceted challenge, from setting up essential accounts to configuring access for various applications, requiring meticulous attention to detail.
Infrastructure Setup
Migrating all servers, software, and networks to the cloud posed a significant challenge, necessitating a seamless transition for end-users accessing the infrastructure in real time.
Pipeline Setup
Configuring a valid action pipeline within strict time constraints proved to be a hurdle, demanding precision in resource management.
Video Capture of Program Execution
Demonstrating the final product to the client through video capture added complexity, requiring synchronization with client and customer availability.
User Acceptance Testing (UAT)
The challenge of UAT stemmed from the heritage program’s origins in the 1930s, making data retrieval and screen recreation a formidable task.
Budget Analysis
Financial challenges included billing issues due to a lack of qualified resources, outdated development environments, manual processes, and restricted access to data.
Overcoming the Challenges
Addressing the multifaceted challenges inherent in mainframe modernization demanded a strategic approach at the technical level. The following key technical aspects were instrumental in overcoming hurdles
-
Customized Template Screen : The legacy system presented challenges with a hung screen and numerous patchwork issues. Our technical team successfully created a customized template screen, replacing the legacy interface. This innovation not only resolved performance issues but also improved efficiency and user experience.
-
Resource Allocation Strategies : Managing resources for Information Management System Data Communication (IMS DC) was a critical technical challenge. To ensure availability, our team adopted a dual-pronged approach. Alongside internal resources, LMTEQ’s experts proficiently handle two projects concurrently. This ensured optimal resource allocation for the mainframe migration
