AWS Lambda responds to the events triggered by your application or your users, and automatically manages the underlying computer resources for you. Back-end tasks like analyzing a new document or processing requests from a mobile app are easy to implement. Your application is divided into small functions, leading naturally to a reactive architecture and the adoption of microservices.</span></p> <p class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"><strong><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">About the Book</span></strong><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";"></span></p> <p class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"><em><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">AWS Lambda in Action</span></em><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";"> is an example-driven tutorial that teaches you how to build applications that use an event-driven approach on the back-end. Starting with an overview of AWS Lambda, the book moves on to show you common examples and patterns that you can use to call Lambda functions from a web page or a mobile app. The second part of the book puts these smaller examples together to build larger applications. By the end, you'll be ready to create applications that take advantage of the high availability, security, performance, and scalability of AWS.</span></p> <p class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"><strong><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">What's Inside</span></strong><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";"></span></p> <ul type="disc"> <li class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l1 level1 lfo1; tab-stops: list .5in;"><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">Create a simple API</span></li> <li class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l1 level1 lfo1; tab-stops: list .5in;"><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">Create an event-driven media-sharing application</span></li> <li class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l1 level1 lfo1; tab-stops: list .5in;"><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">Secure access to your application in the cloud</span></li> <li class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l1 level1 lfo1; tab-stops: list .5in;"><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">Use functions from different clients like web pages or mobile apps</span></li> <li class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto; mso-list: l1 level1 lfo1; tab-stops: list .5in;"><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">Connect your application with external services</span></li> </ul> <p class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"><strong><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">About the Reader</span></strong><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";"></span></p> <p class="MsoNormal" style="mso-margin-top-alt: auto; mso-margin-bottom-alt: auto;"><span style="font-family: "Times New Roman",serif; mso-fareast-font-family: "Times New Roman";">Requires basic knowledge of JavaScript.
