Final answer:
To create Azure resources with ordering, dependency management, parallelism, and idempotency, use Azure Resource Manager (ARM) templates. ARM templates specify resources in a JSON file, ensuring the correct deployment order and avoidance of unintended side effects with multiple deployments.
Step-by-step explanation:
To create resources in Azure with validation steps, ensuring they are created in a specific order based on dependencies and done so in parallel and in an idempotent manner, you can use Azure Resource Manager (ARM) templates. ARM templates are JSON files that define the resources you need to deploy for your solution. When you deploy an ARM template, Azure Resource Manager ensures that all resources are created in the defined order, handling dependencies correctly. This is crucial for resources that must be created before others can exist. ARM templates also ensure that deployments are idempotent, meaning that you can run the same template multiple times and achieve the same state without producing unintended side effects. The use of parallel deployments can speed up the process, as resources without dependencies on each other can be created at the same time.
