Best Practices for Networking in AWS SageMaker
Three years of locking down SageMaker environments across regulated industries taught me one thing early: your networking decisions on day one determine whether the ML infrastructure passes an audit six months later. Teams treat SageMaker networking as an afterthought. Notebook instances get default settings. Models train with full internet access. Then the security review arrives and everybody scrambles. Give the networking layer the same rigor you'd give any production VPC workload.
