The Pay-as-you-go model is a billing option for Azure services where you only pay for what you use, and it is typically associated with various Azure resources. Standard Support refers to a support plan that provides technical support for Azure services.
If you are not using any Azure services like VMs or databases, you can cancel the Pay-as-you-go subscription without affecting your Azure DevOps users and source code repositories. Azure DevOps can be used independently of other Azure services, and your DevOps functionality should remain intact.
However, it's always a good idea to double-check your current subscriptions and billing details to ensure there are no dependencies.
