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!

What is the Serverless Framework?

When it comes to developing and deploying serverless applications, one thing's certain! Developers don't want to waste a lot of their time and effort on setting up the development environments, nor do they want to be concerned with the burden of deploying and managing different versions of their functions. What makes things more complicated is the fact that, sometimes, you end up with a large number of Lambda functions to be used along with other AWS services such as API gateways and DynamoDBs. Looking at this, developers soon realized that there was a strong need for some standardization and structure toward deploying serverless applications, especially when orchestrating multiple functions and complex service integration.

With this in mind and a goal of creating a smooth transition for developers, the greater AWS community started...
