ServiceNow Technology workflows can work in conjunction with a GitOps based platform to create Continuous Delivery (CD) pipelines that are automated and auditable.
For example, in a typical CD model a developer commits code to a repository and issues a Pull Request (PR) that would upgrade application "Foo" from 1.0 to 1.1. An action like that typically requires approval for someone responsible for Production environments.
A ServiceNow workflow could be triggered when the PR is generated and sent to the appropriate person for approval. Once approved another ServiceNow workflow could update the image digest in Foo's application manifest from version 1.0 to 1.1. The GitOps platform using ArgoCD (or FluxCD) would detect that change and upgrade Foo to 1.1.
This results in a fully automated and auditable CD pipeline
