Lambda Function Event Sources - Serverless Architectures with AWS Lambda

Lambda Function Event Sources

Now that you know what goes into the code of a Lambda function, let’s look at the event sources, or triggers, that invoke your code. While Lambda provides the Invoke API that enables you to directly invoke your function, you will likely only use it for testing and operational purposes. Instead, you can associate your Lambda function with event sources occurring within AWS services that will invoke your function as needed. You don’t have to write, scale, or maintain any of the software that integrates the event source with your Lambda function.
