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

Although we have covered quite a few interesting use cases, there are still a lot more event mappings that you can work with when it comes to Lambda, including services such as AWS CodeCommit, AWS Config, Amazon Echo, Amazon Lex and Amazon API Gateway. Try exploring a few of these services and coming up with simple, reusable functions on your own for starters.

The second important thing worth mentioning here is the availability of sample events based on the supported event sources by Lambda. You can use these sample events as base templates when it comes to testing your code with event mappings. This enables you to effectively test your code out without having to enable the trigger in the first place. To know more, check out the sample events page here: http://docs.aws.amazon.com/lambda/latest/dg/eventsources.html.

Remember, although the event mapping...
