The adoption of serverless is on the rise, but until now, little guidance has been available for development teams that want to apply this technology on AWS. This definitive guide is packed with architectural, security, and data best practices and patterns for architects and engineers who want to build reliable enterprise-scale serverless solutions. Sheen Brisals, an AWS Serverless Hero, and Luke Hedger, an AWS Community Builder, outline the serverless adoption requirements for an enterprise, examine the development tools your team needs, and explain in depth the nuances of testing event-driven and distributed serverless services. You'll gain practical guidance for keeping up with change and learn how to build serverless solutions with sustainability in mind. By no means is this book a one-stop solution to all your serverless queries and worries. It is a collection of options and ideas that you can draw upon to prepare your serverless meal according to your and your organization’s dietary requirements. Along with serverless technology, the popularity of several development frameworks, runtimes, build and infrastructure tools, etc., is also on the rise. Consequently, there are as many approaches to implementing your application as there are frameworks and runtimes out there. As suggested by the widespread phrase in the software industry, the code you write today is legacy tomorrow, it is hard to maintain the code you have written today in this fast-evolving technology space.
