title: Which is lower cost, Sagemaker or EC2?
body: <p>For example, ml.p2.8xlarge for training job at ap-northeast on Sagemaker takes 16.408 USD / hour, but p2.8xlarge for on-demand at ap-northeast on Ec2 takes 12.336 USD/hour. Is it cheap to just train the DL models on Ec2 rather than Sagemaker if we only use it for training?</p>
