In this chapter, we learned how to deploy Lambda functions as infrastructure as code via SAM, which is a new way of writing and deploying Lambda functions. This makes it easier to integrate with other IaaS services, such as CloudFormation. We also learned about the AWS CloudFormation service, which is the service that allows and facilitates infrastructure as code. We also learned how security works inside SAM code and how to configure VPC and subnet settings.
In the next chapter, you will be introduced to Microsoft Azure functions, along with configuring and understanding the components of the tool.
