Foreword

At some point in the next few years we’re going to see the first billion-dollar startup with a single employee, the founder, and that engineer will be using serverless technology. Serverless takes the permissionless world of IT today to its logical conclusion—developers no longer need to wait for anyone to sign off on a new project. Developers can get started in minutes building apps without worrying about servers, infrastructure, data stores, or configuration tools. From a business perspective, serverless is revolutionary because the developer doesn’t need to pay until the point of use. Unless a customer is using a service, the developer doesn’t need to pay for it. This is the on-demand economy in action.

AWS Lambda in Action is a great introduction to serverless technology in general and AWS Lambda in particular.

I first met the author, Danilo Poccia, an Evangelist at Amazon Web Services, at a briefing for industry analysts at an Amazon event in London. I was immediately pulled in by his down-to-earth approach and his infectious enthusiasm for all things serverless. As a developer Evangelist, Danilo has a wealth of experience explaining serverless technology from the ground up, and it really shows in this book.
