S3 Access Points
Explore how to use AWS S3 access points to manage granular, secure access to shared buckets using separate policies and VPC restrictions. Learn about S3 Object Lambda to dynamically transform data on GET requests, enabling efficient and flexible responses without duplicating datasets. This lesson helps you maintain strict data control and reduce operational complexity in multi-tenant environments.
We'll cover the following...
As data lakes and multi-tenant architectures grow in complexity, managing granular access to shared S3 buckets becomes increasingly difficult using only bucket policies and IAM roles. S3 access points are a scalable and secure way to manage data access at scale by creating separate entry points, each with its own policy, for different applications, users, or services accessing the same bucket.
Access points help enforce the principle of least privilege. Instead of granting users access to an entire bucket, we create an access point that exposes only a specific prefix (e.g., customer-data/region-east/) and apply fine-tuned ...
