I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.

计算和网络隔离同时也提升了安全性并降低了攻击者获取数据访问的风险。作为一
个安全最佳实践，所有
SageMaker
组件都应与不能直接连接互联网的虚拟私有云
（
Virtual Private Cloud
，
VPC
）一同使用。这需要我们仔细配置
IAM
角色，
VPC
端
点（
VPC Endpoints
），子网和安全组（
security groups
）的策略，使其对
Amazon
S3
，
SageMaker
，
Redshift
，
Athena
，
CloudWatch
以及任何在数据科学工作流中使用
的其他
AWS
服务具有最小权限的访问。在第
12
章，我们会更深入了解如何使用计
算隔离、网络隔离、
VPC
端点和
IAM
策略来保证数据科学环境的安全。
