AWS Lambda: A Guide to Serverless Microservices

AWS Lambda – A Guide to Serverless Microservices takes a comprehensive look at developing “serverless” workloads using the new Amazon Web Services Lambda service. Lambda enables users to develop code that executes in response to events – API calls, file uploads, schedules, etc – and upload it without worrying about managing traditional server metrics such as disk space, memory, or CPU usage. With its “per execution” cost model, Lambda can enable organizations to save hundreds or thousands of dollars on computing costs.

With in-depth walkthroughs, large screenshots, and complete code samples, the reader is guided through the step-by-step process of creating new functions, responding to infrastructure events, developing API backends, executing code at specified intervals, and much more.
