Mastering AWS Lambda

Overview of this book

AWS is recognized as one of the biggest market leaders for cloud computing and why not? It has evolved a lot since the time it started out by providing just basic services such as EC2 and S3 and today; they go all the way from IoT to Machine Learning, Image recognition, Chatbot Frameworks, and much more! One of those recent services that is also gaining a lot of traction is AWS Lambda! Although seemingly simple and easy to use, Lambda is a highly effective and scalable compute service that provides developers with a powerful platform to design and develop Serverless event-driven systems and applications. The book begins with a high-level introduction into the world of Serverless computing and its advantages and use cases, followed by a deep dive into AWS Lambda! You’ll learn what services AWS Lambda provides to developers; how to design, write, and test Lambda functions; as well as monitor and troubleshoot them. The book is designed and accompanied with a vast variety of real-world examples, use cases, and code samples that will enable you to get started on your Serverless applications quickly. By the end of the book, you will have gained all the skills required to work with AWS Lambda services!

Planning your next steps

There's a lot you can achieve by working with SAM as well as with Step Functions when it comes to building and deploying Lambda applications. But besides these services, you can still use other AWS services such as AWS Code Build and AWS Code Deploy. Code Build can be leveraged to build, locally test, and package your serverless application, whereas Code Deploy can be used to automate the steps for your application's release management. You can find detailed implementation steps for the same using this link: http://docs.aws.amazon.com/lambda/latest/dg/automating-deployment.html

The second AWS service worth trying out is Amazon Simple Workflow Service or SWF. Although step functions are a small part of SWF's overall functionality, it greatly enhances the overall experience of orchestrating and running distributed serverless apps when compared...
