People who work with the Microsoft technology stack can't get away from Azure anymore. You can also see Microsoft's clear cloud first philosophy. With that a lot of resources are deployed into Azure. But when it comes to creating virtual infrastructure IT pros and administrators are often still using the portal or maybe PowerShell to get their job done. But these days the complexity is so high, that you can't get away from the methodology of Infrastructure as Code. And for Azure the Azure Resource Manager (ARM) is the center point of every service. With ARM we declare infrastructure configuration. We care about the "What" and not the "how". But what is the best way? In this session I will give best bits and best practices on how to approach to use and develop your ARM templates. Basic knowledge of the Azure Resource Manager and it's template technology is appreciated.
