Question

Your team maintains an Azure Pipelines YAML pipeline that must deploy the same web application to four different Azure regions (East US, West Europe, Southeast Asia, and Australia East). Each region deployment performs identical steps but targets a different Azure resource group and service connection. You want to avoid duplicating the deployment stage four times in the pipeline YAML while keeping the file maintainable. Which approach should you implement?

Accepted Answer

Create a stage template that accepts region parameters, then use a parameter of type 'object' containing the region list and iterate over it with a 'each' expression to insert one stage per region.

Answer

Define a single deployment stage and use a matrix strategy in the deployment job to fan out to all four regions in parallel.

Answer

Create four separate YAML pipeline files, one per region, and trigger them from a parent pipeline using pipeline resource triggers.

Answer

Copy the deployment stage four times and use runtime parameters to disable the stages that should not run for a given execution.
