AWS Lambda is an event-driven compute service which runs your code (Lambda functions) in response to events, such as changes to data in an Amazon S3 bucket. In the case of AWS Lambda functions, the role you assign to a function will dictate the permissions the function will have while it executes. For instance, a function processing S3 uploads with AWS Rekognition could be connected to a number of S3 buckets across several accounts, with all image processing charges aggregated and billed under one account. When the lambda function is loaded it will download the PyTorch model from S3 and load the model into memory. These commands map to Spring MVC controllers that will emit events to functions that are deployed to AWS Lambda. It is a very good skill to learn that opens doors to powerful. While the tutorial uses baeldung-sam-bucket in the following, be aware that bucket names must be unique, so you have to choose your name.
