Azure Resource Manager vs. Pulumi

Azure Resource Manager (ARM) is Microsoft's deployment and management service for Azure, providing a unified layer to create, update, and delete resources within your Azure account. It enables users to manage their infrastructure through declarative templates, ensuring consistent and repeatable deployments across various environments. By organizing resources into groups, ARM simplifies monitoring, access control, and billing, offering a streamlined approach to resource management.

Pulumi lets you build, deploy, and manage cloud infrastructure in the programming languages you already use, on any cloud. Developers and platform engineers write infrastructure in TypeScript, Python, Go, C#, Java, or YAML, with the same loops, functions, classes, package managers, IDEs, and test frameworks they use everywhere else. No domain-specific language to learn. Application and platform teams work from one codebase and one workflow, whether they're shipping to public, private, hybrid, or multiple clouds.
