consumer banking in cloud
summary
Goldman Sachs runs Marcus as a cloud-native consumer banking platform and acts as the Apple Card underwriter. It launches Amazon seller loans with a two-step instant credit decision, enforces PCI (about 16 controls), and attributes 45% of U.S. identity theft to credit cards ($1.9B losses in 2019). Infrastructure lives on AWS using Pivotal Cloud Foundry, Terraform/Terraform Enterprise with Sentinel, HashiCorp Vault, Kafka, S3, Splunk and Ansible; ML-based fraud detection, no-console changes, and end-to-end transaction latency targets of 3–5 seconds.
