ACI Worldwide and Cognizant test card processing software on AWS

ACI Worldwide (NASDAQ: ACIW) and Cognizant (NASDAQ: CTSH) announced results of joint performance testing of BASE24-eps, a card acquiring and issuing software component, deployed on Amazon Web Services.

According to a press release from ACI Worldwide, the testing sustained more than double the target transaction load for 30 minutes with no failed transactions. Across the full test, the system processed more than 4.6 million transactions without a single failure.

The test environment ran on Amazon EC2 with Amazon RDS for PostgreSQL. Observability was instrumented to the OpenTelemetry standard and monitored through Amazon CloudWatch, allowing real-time visibility into transaction flow, system health, and throughput.

Cognizant designed the target architecture, provisioned the environment, and deployed BASE24-eps using an AWS account operated by ACI. Installation and deployment were automated. The test was conducted in a non-production environment.

"This testing put BASE24-eps under sustained load on AWS, and it ran well past target without a failed transaction," said Ajmal Syed, Chief Architect and Technical Fellow at ACI Worldwide.

"Banks do not move payment systems on optimism. They move on evidence," said Nitin Bahl, Strategic Business Unit Head, Fintech and Payments at Cognizant. "Our engineers built a working environment on AWS and ran sustained load through it."

The companies noted that production deployment would require additional steps, including resilience across availability zones, failover and disaster recovery testing, security hardening, further nonfunctional testing, and payment network certification.
