This presentation delves into the journey of transitioning an on-premises monolithic real estate application to a fully serverless, event-driven microservices stack on AWS. Explore the compelling business drivers that necessitated this shift, from traffic demands and team scalability to architectural flexibility. We'll unpack the challenges, from navigating many service choices to the cost implications. At the same time, we'll celebrate the undeniable advantages: improved security through AWS's shared responsibility model, the economic flexibility of a pay-as-you-go approach, and remarkable reliability and scalability.
