Scaling cross-account AWS KMS–encrypted Amazon S3 bucket access using ABAC
This blog post shows you how to share encrypted Amazon Simple Storage Service (Amazon S3) buckets across accounts on a multi-tenant data lake. Our objective is to show scalability over a larger volume of accounts that can access the data lake, in a scenario where there is one central account to share from. Most use […]
