Local Docker execution does not test Azure subscription quota. Deployment requires Azure-side capacity authorization.

A new registry does not authorize the existing image pull. Confirm the runtime identity, registry scope, image reference and pull-capable role assignment.

Read-only registry credentials cannot publish new manifests. Scope and role assignment must allow writes.

Managed identities supply Entra tokens to supported services without embedded long-lived application secrets.

A backup is a recovery operation for an existing application, not the runtime hosting service itself. Provision a supported App Service web app and Python runtime first.

Autoscale evaluates supported metrics and can adjust worker count under configured thresholds. It requires a plan that supports autoscale.

Slot availability doesn't make an unsupported application language or version available. Resolve OS and runtime stack compatibility rather than adding a staging environment.

Key Vault references can resolve secrets into app configuration under supported identity and vault settings, avoiding plaintext storage.

HTTPS Only requires encrypted transport but does not, by itself, set the minimum accepted TLS protocol version.

A reverse proxy changes the observed source path. The app's inbound allow rules must reflect the trusted upstream in a supported manner.

Horizontal scaling increases the number of workers serving the app. It is distinct from increasing each instance's size.

Vertical scaling increases per-worker resources, unlike adding more workers. Plan limits and compatibility must be reviewed.

A private endpoint governs client connectivity and does not change which App Service features the pricing tier provides. Deployment slots require a hosting plan that supports them.

A staging-slot creation operation still requires an eligible App Service plan. Verify slot availability in the plan and upgrade or change the tier before attempting the deployment.

App Service offerings vary by operating system and runtime. A build that runs locally may need a compatible hosting configuration. This matters here because a web app cannot create a deployment slot at its current hosting tier.

Horizontal scaling increases the number of workers serving the app. This is distinct from increasing each instance's size.

App Service backup does not automatically guarantee consistent recovery of every external database. Dependencies need coordinated RPO and RTO.

Sticky configuration distinguishes production and staging dependencies. Swapping nonsticky connections can produce incorrect environment access.

Key Vault references can resolve secrets into app configuration under supported identity and vault settings, avoiding plaintext storage. This matters here because a developer increases instance count but a single-threaded request still suffers from insufficient per-worker memory.

Autoscale can add workers to distribute concurrent traffic, but a single memory-bound request still runs within the limits of one worker. Check memory profiling and scale up the App Service plan when appropriate.

Horizontal scaling increases the number of workers serving the app. It is distinct from increasing each instance's size. This matters here because a developer increases instance count but a single-threaded request still suffers from insufficient per-worker memory.

Global peering joins network paths, not physical locations. Cross-region transfer and latency considerations still apply.

A NIC can hold additional private addresses only within its applicable subnet, but that does not eliminate overlapping VNet address ranges. Peering requires independently routable network address spaces.

Peering checks VNet CIDR ranges, not just subnet names. Keeping identical parent address spaces leaves routing ambiguous despite labels and distinct subnets.

Suppressing propagated gateway routes can remove learned destinations from effective tables. Custom routing must replace them explicitly if suppression is intentional.

Ordinary Azure VNet peering does not resolve overlapping address spaces by itself. Distinct reachable prefixes are needed.

Peering rejects overlapping VNet address spaces regardless of individual subnet size. At least one parent VNet range must be changed to a nonoverlapping plan.

Peering connections may need synchronization after address changes. A new address prefix must be represented in the reachable topology.

Separate subnets can be carved from an appropriate free VNet range. Global renumbering is unnecessary and does not define the tier subnets or their access policies.

The /25 occupies part of the /24 range. Azure subnet definitions cannot overlap even if they have different names.

A subnet must be contained within its own VNet address blocks. Modifying another network's addresses doesn't repair an invalid local subnet definition.

Azure Bastion discovers its required subnet by specific naming. An arbitrary subnet alias cannot replace it.

Static private IP allocation makes the address stable across supported VM lifecycle events. DNS records must agree with the NIC configuration.
