In the Cloud

Project profile

Engagement: Azure hub-spoke network foundation and operational handover
Focus: Segmentation, routing, shared connectivity, private access, and inspection
Output: Network design, routing decisions, configuration evidence, and operations notes

Shared paths with clear boundaries

Cloud workloads needed access to shared services and private destinations without creating a flat network. The design had to make traffic paths, inspection points, ownership, and failure impact understandable before more workloads were connected.

The hub provided shared connectivity and control services, while spokes created workload boundaries. This pattern was used as a starting point, not as a fixed topology for every environment.

Foundation coverage

Hub and spoke boundaries, ownership, and address planning
Peering, route propagation, and user-defined routes
Firewall, inspection, egress, and inbound access paths
DNS, private endpoints, and hybrid connectivity
Monitoring, diagnostics, change control, and support

Decisions recorded

Traffic flows were documented by source, destination, purpose, and control point. Shared routing decisions were separated from workload-specific rules, and route or firewall changes included validation and rollback expectations.

What to be aware of

Hub-spoke simplifies ownership only when route and DNS responsibility are explicit.
Peering does not provide transitive routing by itself.
Private endpoints add DNS and lifecycle dependencies.
Central inspection can become a shared failure or capacity point.

Outcome

Workload teams received a consistent network landing pattern with defined shared services and boundaries. Connectivity could expand without redesigning the core path for each workload, while exceptions remained visible.
