Our Azure reference focuses on ARM deployment failures, Entra ID authentication and authorization errors, and storage/runtime service exceptions. Each guide maps provider messages to actionable checks across tenant, subscription, resource group, and policy layers used in real operations.
These are the highest-signal Azure pages for common production failures and the best first routes for internal linking and early user navigation.

Azure ResourceModified means a write targeted resource state that changed after the caller read it, so the stale mutation was rejected.
Azure ResourceNotFound means ARM or a resource provider could not resolve the requested resource ID in the exact subscription, resource group, provider, type, and location context.
Azure ResourceQuotaExceeded means a deployment or scale operation exceeded an Azure quota dimension for the subscription, region, resource family, or provider scope.
Azure Storage returns `ServerBusy` (503) when request load exceeds what the target partition/account can handle at that moment.
Azure StorageAccountAlreadyTaken means the requested storage account name is unavailable because storage account names are globally unique across Azure.
ARM returns `StorageAccountNotFound` when the referenced storage account name, resource group, or subscription context does not resolve.
Azure returns `StorageAccountQuotaExceeded` when storage account capacity, ingress/egress, or request-rate limits are exceeded for the workload.
Azure surfaces `StorageContainerQuotaExceeded` when container/account growth or throughput constraints block additional storage operations.
Azure SubscriptionNotFound means ARM cannot resolve the target subscription in the caller tenant, context, deployment scope, or access graph used by the request.
ARM returns `SubscriptionRequestsThrottled` when subscription or tenant request limits are exceeded and the control plane responds with throttling.
Azure Table service returns `TableNotFound` when the target table name does not exist in the addressed storage account endpoint.
Azure returns `Unauthorized` (401) when request authentication is missing, invalid, expired, or mismatched for the target endpoint.
Azure returns `ValidationError` when request values violate provider-side semantic rules, even if request syntax is structurally valid.
Azure returns `VMExtensionNotFound` when a VM operation references an extension resource name that does not exist on the target VM.
Azure returns `VMNetworkInterfaceNotFound` when a VM operation references a network interface that cannot be resolved in the current scope.
