Title

AWS re:Invent 2023 - Designing & Migrating an AWS-Native Mobility Solution in an M&A Setup (ENT104)

Summary

Rajat Sharma from Zensar and Tapas Samanthare from MSTS Tolls presented a case study on cloud-native enterprise transformation during M&A.
MSTS Tolls, a Shell portfolio company, transitioned from legacy applications to cloud-native to improve scalability and comply with GDPR.
The partnership with Zensar was crucial, focusing on domain-driven microservices architecture and addressing API redundancy and other technical challenges.
The migration strategy involved a one-team culture, a pod-based model, and a focus on business viability, human desirability, and technology currency.
The migration faced challenges such as multiple stakeholders with different views, short timelines, and the need to align with Shell's stringent standards without automated discovery tools.
Despite these challenges, the migration was completed in 3.5 months with zero business disruption, showcasing the benefits of cloud-native transformation.

The transition to cloud-native architecture is essential for scalability and compliance with regulations like GDPR, especially in a complex, multi-country context like Europe.
A successful cloud-native transformation in an M&A context requires a strong partnership and a shared vision between the acquired company and the assisting technology firm.
Domain-driven design and microservices architecture are critical in aligning technology with business needs, but they can introduce challenges such as API management and redundancy.
The pod-based model and one-team culture facilitated collaboration and streamlined the migration process, emphasizing the importance of organizational culture in technical projects.
The use of AWS well-architected framework standards and a focus on building a solid foundation are key to ensuring a successful migration and future scalability.
The case study highlights the importance of flexibility and adaptability in M&A scenarios, where pre-existing standards and governance models must be reconciled without the luxury of automated discovery tools.
The ability to execute a complex cloud migration within a short timeframe and without business disruption is a testament to the effectiveness of the methodologies and frameworks employed by Zensar and MSTS Tolls.
