Summary

In this chapter, we learned how to use Eclipse with the AWS Toolkit plugin, and we used Java to create and test different Lambda functions. First, we created and tested a Lambda function with a simple string input/output, then a Lambda function that is triggered through S3 events, and, finally, a serverless project that consists of two Lambda functions that write to or read from DynamoDB and S3, respectively. In the next chapter, we are going to take a look how to program AWS Lambda using Python.
