如何使用Lambda触发S3存储桶中的应用程序？

Question

I have an application written in java which is used for creating and sending mail to users. I have zipped this code and uploaded this code to S3 bucket.

How can I trigger this application with the help of Lambda?

I have created a Lambda function and attached the path to Lambda.

Answer 1

If you have created the Lambda function and pointed the function to your code, then Lambda will call the handler function within your code.

Lambda does not "run your application". Rather, it calls the handler, passing in information about how the function was invoked.
