Seems everyone is writing an app on AWS these days, but they often only test manually using the AWS console: Great for a simple dollop of sample code; disastrous for anything complex, valuable, and growing. Rob provides some very (very very...very) simple app code he built for a client as an "architectural spike," including a "Lambda Function" (a fancy way of saying "cloud code"). He also demonstrates how he tests the Lambda Function, both in the AWS(/SAM) cloud, and locally with automated unit-tests. Hopefully, Amazon does NOT set the "demo bit" (the one that plagues demos with technical issues) during Rob's session.
