AWS Lambda is a compute service through which you can run your functions. It will run your functions without the need for you to provision or manage any compute infrastructure. AWS Lambda can not only execute your functions, but can also easily scale to thousands of executions per second. As the server management is abstracted away from the developer, they can just focus on solving the business problem rather than having to also focus on server management and scaling the solution. The other big benefit in terms of cost is that you only pay the compute cost for the time AWS Lambda is executed, which provides you with higher utilization of resources at a significantly lower price than what you would be typically paying if you were to run the compute infrastructure all the time. With AWS Lambda, you are charged for every 100 ms your function executes and the number...

Overview of this book
Serverless applications and architectures are gaining momentum and are increasingly being used by companies of all sizes. Serverless software takes care of many problems that developers face when running systems and servers, such as fault tolerance, centralized logging, horizontal scalability, and deployments.
You will learn how to harness serverless technology to rapidly reduce production time and minimize your costs, while still having the freedom to customize your code, without hindering functionality. Upon finishing the book, you will have the knowledge and resources to build your own serverless application hosted in AWS, Microsoft Azure, or Google Cloud Platform, and will have experienced the benefits of event-driven technology for yourself.
This hands-on guide dives into the basis of serverless architectures and how to build them using Node.js as a programming language, Visual Studio Code for code editing, and Postman for quickly and securely developing applications without the hassle of configuring and maintaining infrastructure on three public cloud platforms.
