In the previous chapter, we saw how easy it is to build and integrate your applications and third party services with AWS Lambda functions. In this chapter, we will be taking things up a notch by learning how to design and build simple serverless applications with Lambda and a few other AWS services in the form of Serverless Application Model (SAM) and a newly launched service called as Step Functions.
In this chapter we will be learning:
- What the SAM template is and how to build serverless applications with it
- Using SAM to build and deploy serverless applications using simple examples
- Introducing AWS step functions
- Building coordinated Lambda services using step function's visual workflows
So without any further delays, let's get started!
