Why Azure Teams Are Moving from ARM Templates to .NET

Azure Resource Manager (ARM) templates, often criticized for their complexity and limitations, face challenges such as lengthy, error-prone deployments and a lack of support for certain key services. In contrast, Pulumi offers a more efficient alternative by allowing Azure infrastructure to be defined using familiar programming languages like C#, Python, TypeScript, or Go, providing benefits like type safety, full IDE support, and easier testing and reuse. Pulumi integrates seamlessly with existing .NET tooling, supports a wide range of Azure services, and facilitates infrastructure management akin to software engineering, promoting modular, testable, and scalable solutions. This makes Pulumi a compelling choice for organizations already utilizing C# and .NET, especially with its capability to share libraries and logic between services and integrate with platforms like Azure DevOps and GitHub Actions.
