In its various lines of business, including decision and credit and portfolio risk management, Discover faced the challenge of making sure that it could launch its services fast enough. “We wanted to make decisions quicker and get to insights faster so that we could respond faster to our customers,” says Rahul Gupta, AI/ML expert platform engineer at Discover.

The high compute power available was used for parallel model training, which reduced the processing time of 30 million records from days to hours.
Using 16 CPUs, the processing took 6.5–7 hours, while a single-GPU setup took 23 minutes.
Using multiple GPUs brought the processing time down to 4 minutes but also increased costs.
reduction in engineering and platform costs 35%

Reported impact

Business outcome

The Discover team now wants to explore using Amazon S3 to add event-based activations for further automation. It currently uses a scheduler to schedule daily tasks, such as identifying and classifying customers. Key reported metrics include sample size instead of 20% for better model accuracy and results 100%; reduction in engineering and platform costs 35%; Using 16 CPUs, the processing took 6.5–7 hours, while a single-GPU setup took 23 minutes..

Solution

Learn how Discover Financial Services, a digital bank, used AWS services to build a generative AI/ML solution for better decision-making and customer service. Financial institutions need to respond quickly when situations change, and customers look to these institutions for accurate analysis and fast responses. Digital bank Discover Financial Services (Discover) wanted to enhance its customer service by speeding up analytics, insights, and decision-making. It used Amazon Web Services (AWS) to create a data science solution that its scientists and analysts could use for machine learning (ML) and generative artificial intelligence (AI) workloads. The solution helped speed up time to market, mitigate risk, and improve the customer experience.

Data flow

Source data enters the Discover Financial Services workflow through its application services, stored or indexed in Amazon S3, Amazon EFS, processed with Amazon EC2 P4 Instances, Amazon EC2 P3 Instances.

Scoring methodology

How scores are calculated

Customer Reference Value measures usefulness as a customer reference. Evidence Confidence measures the quality and traceability of available evidence, not independent verification.

Customer reference value95/100
  • Problem clarity20/20
    Measures whether the customer's operational problem is specific enough to compare.
  • Implementation depth20/25
    Rewards named components, data flow, integrations, and architecture detail.
  • Outcome specificity20/20
    Measures whether the reported benefit is concrete rather than a generic claim.
  • Quantified impact25/25
    5 metrics describe measurable impact.
  • Deployment scale10/10
    Rewards evidence of a live or scaled deployment and meaningful integration scope.
Evidence confidence87%
