As cloud computing continues to evolve, talk of serverless computing is becoming more and more prominent. The problem is, that serverless or (functions as a service) requires a shift in thinking, as it can differ greatly from traditional computing offerings like physical servers, or a VPS. We have successfully made the switch at OpenFit, and our backend services are now running 100% in Lambda (AWS’ serverless offering). As a result we have developed some best practices and methodologies we want to share with you. In this talk we will discuss the particulars of serverless computing and development. Along with information regarding what we have learned while developing OpenFit.
