What is the difference between AWS Services and AWS Resources?
The resource is what you create inside the service.
Let’s see an example:
You create a bucket inside s3: the bucket is the resource and s3 is the service that lets you create the resource. That resource will have a unique Amazon Resource Name also known as ARN that will provide storage and/or static website hosting service.
It’s just a distinction between the service itself, and the things that you create inside those services.
