We've reached the part of this book where we get to use what we've learned so far, put our understanding together, and move on to the next level of serverless application development. We've taught you the base knowledge that you need to succeed when you start your first project. In this chapter, we will turn simple lambda function development into full-blown serverless application development. We'll explore an application framework that accelerates our progress and makes it easy to build and deploy.

In this chapter, we'll cover the following topics:

• Understanding the need for a framework
• Exploring the core concepts of the Serverless Framework
• Deploying your first service
• Testing and debugging
