Client
Driving Reliability for the Automotive Aftermarket
Our client is a top retailer and distributor of automotive parts and accessories. They help individuals and businesses keep their vehicles running safely and reliably. Focusing on innovation and excellent service, they have earned a strong reputation for providing dependable solutions and outstanding customer support.
Challenges
Modernizing a Payment Ecosystem
Our client, a leading automotive parts retailer, is known for delivering reliable service and helping customers keep their vehicles running safely. Their credit card authorization (CCA) system handled real-time transactions across the US and Mexico, but it operated on an aging on-premises environment that could no longer keep up with growing business needs.
With physical data centers set for shutdown, the legacy system created risks around scalability, performance, PCI compliance, and operational reliability. Slow response times, rising transaction volumes, and outdated technology made it difficult to support both store and eCommerce experiences.
To modernize, our client needed to overcome tight timelines, skill gaps in GCP and microservices, mandatory PCI requirements, and the need to rewrite applications on a modern Java-based stack—setting the stage for a critical cloud transformation.
Solution
A Modern, Cloud-Ready Payment Platform on Google Cloud
To ensure their credit card authorization (CCA) system could keep pace with expanding retail operations and rising transaction demands, our client needed a modern, cloud-ready foundation.
Hexaware supported them in transitioning this mission-critical platform to Google Cloud, helping them build a more secure, elastic, and future-ready payment ecosystem.
Backed by our expertise in cloud modernization services, we moved key components with a comprehensive migration to Google Cloud—including CCAuth, CreditDebit, ZeStore, and the PCI database—into Google Cloud. This provided our client with a resilient, scalable, and PCI-aligned foundation that better supported their operational needs.
Modernizing the Application for Cloud Performance
With Application Modernization Services, the legacy application stack was upgraded to JDK 17 and Spring Boot 3, and restructured into microservices. This improved performance, maintainability, and the speed at which new updates could be delivered.
Achieving Elasticity with GKE
Hexaware’s Containerization & Kubernetes Enablement Services enabled the deployment of modernized components on Google Kubernetes Engine (GKE), giving our client automatic scaling, faster releases, and strong multi-region resilience.
Strengthening Security and Connectivity
Through API & Security Services, the solution integrated Apigee Gateway and PingID to establish secure API communication and stronger authentication, ensuring safe interactions with Worldpay, BBVA, mainframes, and digital channels.
Addressing Constraints with Precision
Despite aggressive timelines and the need for specialized modernization skills—microservices, Java upgrades, Kubernetes, and secure API design—our team executed a comprehensive migration and modernization strategy without disrupting business operations.
Solution Architecture Overview
The modernized CCA ecosystem is deployed across the Google Cloud US Central and US East regions, with secure integration to on-premises mainframes, payment gateways, and monitoring platforms.
The diagram shows how consumer-facing applications route through Apigee and PingID, how CreditDebit, ccAuth, ZeStore, and the PCI database operate in GCP, and how the system maintains secure, low-latency connectivity with BBVA, Worldpay, and legacy settlement systems.
