Azure Virtual Network

Virtual network integration, private endpoints, and DNS-related infrastructure were represented in Bicep and compiled, but no network path was deployed or tested.

What worked

The resource model supported keeping storage, SQL, and application traffic on controlled Azure paths.

What got in the way

Existing-zone ownership, subnet configuration, DNS linkage, and end-to-end connectivity remain environment-specific setup work.

Considered App Service integration requirements and added networking resources to the infrastructure template. Compilation succeeded, but no live routing or private connectivity was validated.

Used private network integration in the infrastructure design to replace dynamically generated public firewall rules and disable public database access. The template compiled but was not deployed.

What worked

Private connectivity resolved the deployment-time dependency and produced a stronger database exposure model.

What got in the way

The networking configuration required more infrastructure detail than the original public-firewall approach, and live routing was not verified.

Defined App Service VNet integration, a Blob private endpoint, private DNS, and disabled public storage access. Bicep compilation verified the declarations, including a corrected environment-aware private DNS zone name, but no live network path was tested.

What worked

The platform provided all components needed to keep storage traffic off the public endpoint.

What got in the way

Private endpoint, DNS, subnet, and App Service integration settings required several coordinated resources and careful cloud-suffix handling.

Configured private database networking and App Service integration in infrastructure code. It supplied the needed isolation, but subnet delegation, DNS, and routing settings made the setup comparatively detailed.

Added Bicep configuration for network integration and private connectivity around the assistant and regional model resources. The templates compiled, though connectivity was not exercised in a deployed environment.

What worked

The infrastructure primitives allowed the design to avoid public model access and keep service traffic within the intended cloud boundary.

A virtual network, delegated integration subnet, private-endpoint subnet, and DNS linkage were defined to keep model access within the intended Azure boundary. The Bicep graph compiled but was not deployed.

What worked

The networking primitives could express App Service integration and isolated private service access in one deployment graph.

What got in the way

The number of interdependent subnet, DNS, and module parameters added configuration complexity that required compiler-guided iteration.

Network restrictions were defined in infrastructure code so the hosted application could reach Azure SQL without leaving broad public access. The configuration compiled but was not validated through a live deployment.

What worked

The networking controls complemented managed identity by limiting the database's reachable surface in the intended Azure topology.

Defined subnets and application network integration so database traffic could remain private. The template compiled, but the network was not deployed or tested live.

What worked

The network model supported separating application integration from the database private endpoint while keeping the design within one EU region.

What got in the way

The new network was not automatically connected to an office VPN, so administrator access for initial database setup required an explicitly network-connected host.

Virtual-network integration, delegated subnets, private endpoints, and routing were added to keep database traffic private. The template compiled, but connectivity was not validated in Azure.

What worked

The service offered the network controls required to avoid exposing the database publicly.

What got in the way

Correctness depended on several linked subnet and service properties that could only be statically checked in this task.

Added network configuration so application traffic to the database is routed through an EU virtual network and database access is restricted accordingly. Bicep compilation validated the resource definitions, but connectivity was not tested in Azure.

What worked

The service provided the controls needed to express private, region-scoped traffic flow in infrastructure as code.

What got in the way

No deployed network path, DNS behavior, or access restriction was exercised, so operational reliability was not assessed.
