Model deployment with internal data

Your best bet is to put the data in S3 if possible. S3 integrates directly with SageMaker so it should be seamless.

Yes the data is stored in S3. Do you mean I can simply download the data from S3 bucket using boto3 (say in the function the loads the model)?

Yes. Here is a sample snippet of code

import boto3

s3 = boto3.client('s3')

s3.download_file('BUCKET_NAME', 'OBJECT_NAME', 'FILE_NAME')

s3 = boto3.client('s3')

with open('FILE_NAME', 'wb') as f: s3.download_fileobj('BUCKET_NAME', 'OBJECT_NAME', f)
