In this chapter, we learned how to a write a Lambda function in Go from scratch. Then, we covered how to create an execution role for Lambda to generate event logs to AWS CloudWatch. We further learned how to test and invoke this function manually from the AWS Lambda Console.
In the next chapter, I will walk you through how to use triggers to invoke Lambda functions automatically and how to build an unified RESTful API on top using the AWS API Gateway to execute Lambda functions in response to HTTP requests.
