Over the past 15 years, the legacy reporting tool had become a patchwork of EPA mandates and code fixes. With more mandates needing to be incorporated, it was in the Minnesota Department of Health Environmental Health’s best interest to start anew using the Amazon Web Service Cloud (AWS) to innovate and modernize. In this session, you’ll hear the story of our continuing journey from on-premise monolithic legacy application to cloud-based Serverless architecture. We’ll outline the successes and pitfalls we found along the way as we replaced a legacy reporting tool with cloud-based Serverless architecture.

We will discuss the steps we took to create the new reporting process; how we used secure Restful APIs designed in swagger and implemented as AWS API Gateways; how both the UI and APIs were secured using IDAM implemented in Active Directory and Keycloak; and how data processing was handled using serverless orchestration implemented in AWS Step Functions and processed using a multitude of functions as a service (FaaS) implemented as AWS Lambda Functions.

We will discuss what we learned along the way, what worked well and what we would do differently, and how we jump started the process by working with an AWS cloud services architect. We’d also like to share how effectively our DevOps team worked together. Please follow us along on our journey!
