Transforming Avis' rate shop using AWS Cloud
TCS helps upgrade the car rental firm's applications through mainframe modernization
3 MINS READ
Avis Budget Group is one of the world’s largest car rental companies operating in 180 countries from over 11,500 locations. Avis is focusing on reinventing the car rental experience through data-driven intelligence, and enabling connectivity, convenience and choice through digitalization.
To keep pace with the changing industry dynamics, Avis needed to transform its legacy mainframe platform. Rate Shop, the company’s primary revenue-generating product, needed to be re-architected to be cloud-ready and provide the flexibility to adjust pricing in real-time to drive optimal demand and meet customer expectations. Rate Shop accounts for 70% of the transaction volume on Avis’ IT systems, growing on an average of 25% annually. Re-architecting to a cloud-based environment was a necessity to meet such demand. Along with the immediate goal of reducing operational and licensing costs of legacy applications, Avis also required a seamless cloud migration journey to scale customer engagement and overcome technical debt.
TCS partnered with Avis to transform Rate Shop from a legacy assembler-based, tightly coupled application, running on the mainframe, to a modern C-based application running on the AWS cloud. As part of this transformation, TCS migrated more than 250 legacy databases (DB2 and IMS) to high performance Couchbase database technology on AWS EC2 (elastic compute) cloud instances. IBM’s data replication product, CDC (change data capture) in conjunction with Apache Kafka was leveraged to replicate very large data volumes from the mainframe to cloud in real time.
TCS worked with Avis to design a highly resilient, highly available solution that enabled a low-risk iterative rollout by channel and segment. Using its agile methodology, TCS architected Rate Shop to the AWS cloud to kick start Avis’ digitalization journey. This approach enabled TCS to successfully execute the Rate Shop cloud migration program in just eight months. TCS implemented real-time analytics of Rate Shop operations that resulted in a seamless end user experience on AWS. This fueled the on-demand pricing decisions and timely vehicle availability to match customer needs. To meet the sub-second Rate Shop response time needs, Amazon ECS, Auto Scaling, Elastic Load Balancer, ElastiCache and CloudWatch services were used.
The team established a comprehensive DevOps foundation to automate key tasks related to application integration, cloud provisioning, application configuration, and test case execution. With this implementation, Avis’ ongoing integration and deployment needs were automated and scripted by leveraging native AWS CodeCommit in combination with Jenkins. This also provided greater security controls of the code migration process.
TCS was involved from the ideation stage to incubation and initiation for the mainframe modernization at Avis. Post incubation, TCS successfully helped Avis re-engineer an improved customer experience model for its ongoing digital transformation across the enterprise fostering purpose-led growth.
