Stateful Loan Approval Process with AWS Lambda+EventBridge+SNS+SQS

At DecisionCAMP-2020 we had a lot of discussions about the orchestration of the decision services and how to invoke different decision services when states of the business objects change over time. One of the most popular orchestration technique is a Pub/Sub architecture with State machines. The Challenge “Dynamic Loan Approval” is an example of perpetually running decision-making applications which should be able to learn from already executed transactions and evaluate new facts as they become available. This post describes how we implemented this application utilizing OpenRules-based GUI connected to AWS Lambda, EventBridge, SNS, and SQS.

OpenRules business decision models can be deployed as operational decision services utilizing the Serverless architecture provided by AWS.  Deploying your decision models as AWS Lambda functions you don’t even think about servers and pay only for the execution time your services actually consume.
