Service Connection

An Azure DevOps object that securely stores credentials pipelines use to access external services such as Azure subscriptions, registries, or Kubernetes.

Definition

Azure Resource Manager service connections now recommend workload identity federation (OIDC) instead of stored service principal secrets. Access can be restricted to specific pipelines.

Example

A pipeline deploys to an Azure subscription using an ARM service connection backed by workload identity federation.

Exam tip

Prefer workload identity federation to avoid secret expiry and leakage.
