Cloud Networking
Enterprise Azure Networking
Designing secure Azure networking — Virtual Networks, VPN Gateways, Azure Bastion, NAT Gateway, NSGs, and Hub-Spoke topology.
The Challenge
Enterprise workloads required secure, scalable connectivity with centralized control, hybrid reach, and a topology engineers could reason about and operate confidently.
Engineering Thought Process
A hub-and-spoke topology centralizes shared services and security while isolating workloads. Connectivity, segmentation, and least-privilege access were weighed against operational simplicity to land on a design that scales without becoming opaque.
Architecture
Cloud Networking — reference architecture
Technology Selection
Hub & Spoke VNets
Centralizes shared services and security controls while keeping workloads isolated and independently scalable.
VPN Gateway
Provides secure hybrid connectivity between on-premises networks and Azure.
Azure Bastion
Enables secure management access without exposing public IPs.
NSGs
Enforce network segmentation following least-privilege principles.
Implementation
A central hub hosted shared connectivity and security services with peered spokes for workloads. NAT Gateway managed outbound traffic, Bastion secured access, and NSGs enforced segmentation across tiers.
Challenges
- Networking complexity across peered environments
- Hybrid connectivity and routing design
- Balancing security with operational simplicity

Lessons Learned
Good networking design is felt, not seen — the best topologies make day-two operations boring in the best way.
Engineering Reflection
Documentation diagrams that match production exactly are worth the effort; they prevent more incidents than any single control.
