Built-in Deep Learning frameworks: just add your code
• Built-in containers for training and prediction.
• Code available on Github, e.g. https://github.com/aws/sagemaker-tensorflow-containers
• Build them, run them on your own machine, customize them, etc.
• Script mode: use the same code as on your laptop
No infrastructure work required: simply define instance type and instance count
Distributed training out of the box: zero setup
Pipe mode: stream infinitely large datasets directly from Amazon S3
