Network architecture
Secure, scalable Azure networks — built to last.
Design and build Azure network topologies that are secure by default, auditable in code, and documented so your team understands every traffic flow and every rule.
What’s included
5 areas of focus.
Firewalls
Azure Firewall in a hub with centralised policy management — IDPS in alert or deny mode, application and network rules, DNS proxy. Firewall Policy as code, version-controlled and reviewed in CI.
Load Balancers
Azure Load Balancer, Application Gateway, and Front Door selected by traffic pattern, protocol requirement, and WAF need. Each layer designed with TLS termination, DDoS protection, and health probes configured correctly.
VLAN & Segmentation
Subnet design with Network Security Groups and Application Security Groups — micro-segmentation aligned to workload tiers and regulatory zoning requirements. NSG flow logs to Log Analytics for continuous audit.
Routing
User-defined routes to force traffic through the hub firewall, BGP for ExpressRoute circuits, and route table management in Terraform with documented traffic flows for every subnet.
Private Links & Endpoints
Private Endpoints for PaaS services — Storage, Key Vault, Cosmos DB, SQL, and more. Private DNS Zones auto-registered. Public internet access disabled at the resource level, not just firewalled at the perimeter.
What we deliver
Concrete outputs. Nothing vague.
Every engagement ends with tangible, owned deliverables — not a slide deck that gathers dust. The outputs below are typical for a Networking engagement; scope is agreed during discovery.
- Hub-spoke or Virtual WAN network design in Terraform
- Azure Firewall Policy as code with IDPS configured
- NSG and ASG ruleset with documented traffic flows
- Private Endpoint and Private DNS Zone deployment
- Network architecture diagram and high-level design document
