What is workload identity, and how does it remove static credentials? [Intermediate]
Answer
Workload identity lets an application or workload authenticate to cloud services using its runtime identity rather than a stored static credential. It removes static credentials by binding Kubernetes service accounts, VM identities, or CI identities to cloud IAM roles.
Technical explanation
In Kubernetes, workload identity often maps a service account to a cloud IAM role through projected tokens or metadata integration.
Credentials are short-lived and issued based on trusted identity claims.
It reduces secret sprawl and makes access easier to audit and revoke centrally.
Hands-on example
Example: bind Kubernetes service account payments-api to an AWS IAM role through IRSA/EKS Pod Identity or to a GCP service account through Workload Identity. The pod calls the cloud API without an embedded access key, and the role policy grants only required actions.
