Using AWS Workload Credentials Provider for cross-account secret retrieval and prefetching
By
Derik Wang Derik is a Software Engineer on the AWS Secrets Manager team.
Summary
This article explains how to use two new features of the AWS Workload Credentials Provider: role chaining for cross-account secret retrieval and prefetching of secrets to reduce cold-start latency. It provides a step-by-step guide for configuring IAM role chaining to access secrets across multiple AWS accounts through a single provider instance, and demonstrates how prefetching can improve performance for latency-sensitive applications by populating the provider's in-memory cache ahead of time.

· 3 pulledIf you manage secrets across multiple AWS accounts or need faster secret access for latency-sensitive applications, this post shows you how to meet those requirements using two new features of the AWS Workload Credentials Provider.
By using role chaining, you can access secrets across AWS accounts through a single provider instance by assuming AWS Identity and Access Management (IAM) roles.
Prefetching populates the provider's in-memory cache to reduce cold-start latency.
