Resource Groups and Subscriptions#

Azure organizes resources in a hierarchy: Management Groups > Subscriptions > Resource Groups > Resources. An agent interacts most frequently with resource groups and the resources inside them.

A resource group is a logical container. Every Azure resource belongs to exactly one resource group. Resource groups are regional, but can contain resources from any region. They serve as the deployment boundary, the access control boundary, and the lifecycle boundary – deleting a resource group deletes everything inside it.

Cloud Behavioral Divergence Guide#

Running the “same” workload on AWS, Azure, and GCP does not produce the same behavior. The Kubernetes API is portable, application containers are portable, and SQL queries are portable. Everything else – identity, networking, storage, load balancing, DNS, and managed service behavior – diverges in ways that matter for production reliability.

This guide documents the specific divergence points with practical examples. Use it when translating infrastructure from one cloud to another, when debugging behavior that differs between environments, or when assessing migration risk.
