Architecture vs. Operating Model – A Cloud Conundrum

Large financial institutions are at a crossroads: from the 90ies, the industry invested massively in first-class reliability and resilience, but modern tech is putting pressure, pushing innovation at breakneck speed, creating a fluid transaction ecosystem, and churning out ever-evolving sets of products and tech talent.

In this talk, we will cover our experience liberating the data in the mainframe with a hybrid serverless/containerized solution built on AWS. It’s an architecture with tens of Java serverless functions that live-stream mainframe data to the cloud, using a suite of services capable of operating at hundreds of rps: DynamoDB, Lambda, API Gateway, Fargate. We will do a deep dive on various integration patterns and AWS services that can be used to support them.

We will dedicate a special section to performance optimizations done to reduce the cold start problems and support aggressive performance targets. In the last section, we’ll use Lake Formation to create a data platform that can enable a host of new value-add activities for the entire company.
