AWS Lambda enables developers to focus entirely on their application logic free of infrastructure concerns. Lambda functions can be developed in isolation, deployed in seconds, immediately available with zero downtime, and are (at least theoretically) endlessly scalable. If these properties aren't enough to excite developers the cost is also remarkably cheap. 1 million invocations a month are free.
