Summary

ARM templates are the preferred means of provisioning resources in Azure. They are idempotent in nature, bringing consistency, predictability, and reusability to environment creation. In this chapter, we looked at how to create a modular ARM template. It is important for teams to spend quality time designing ARM templates in an appropriate way, so that multiple teams can work on them together. They are highly reusable and require minimal changes to evolve. In this chapter, we learned how to create templates that are secure by design, how to provision multiple resource instances in a single deployment, and how to pass outputs from one nested template to another using the outputs section of ARM templates.

The next chapter will move on to a different and very popular strand of technology known as serverless within Azure. Azure Functions is one of the major serverless resources of Azure, and this will be covered in complete depth, including Durable Functions.
