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.

• Examine the serverless technology ecosystem and AWS services needed to develop serverless applications
• Learn the approach and preparation required for a successful serverless adoption in an enterprise
• Learn serverless architectures and implementation patterns
• Design, develop, and test distributed serverless microservices on AWS cloud
• Apply security best practices while building serverless solutions
• Identify and adapt the implementation patterns for your particular use case
• Incorporate the necessary measures for observable serverless applications
• Implement sustainable serverless applications in the cloud

Who We Wrote This Book For

Serverless as a technology continues to mature and evolve along with its industry adoption. Due to its unique benefits, it attracts a wide spectrum of technology audiences. When Luke and I were discussing the tone and depth of the content, we wanted it to appeal to developers who are new to serverless, engineers who are familiar with and progressing on their journey with serverless, and architects and CTOs who make some of the core decisions and influence the adoption of serverless in their organizations.

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. This is not a book that delves deep into hands-on implementation examples. Its aim is to teach you the underlying concepts that you can rely on in the future, regardless of your circumstances; to teach you to fish, as it were, rather than feeding you just once.

The book starts with a discussion of the evolution of serverless technology and the preparations necessary for successful adoption. It then introduces you to the core security principles of serverless, leading you through event-driven architecture and implementation patterns. Understanding the core principles guides you through the development cycle and operating your serverless applications in the cloud. The cost of serverless is a key part of its adoption, and we have a chapter dedicated to making you aware of the main cost factors. In addition, modern application development requires thinking about our environmental ecosystem and the world we live in. Sustainability is an essential and core part of cloud operation, and you will learn several patterns and best practices to build and operate serverless applications in a sustainable way. The book closes with a look at how you can make your serverless journey rewarding and refreshing for decades into the future.
