Microsoft Azure
Deep dives into Azure hybrid patterns, focusing on seamless connectivity. Master Virtual WAN, global transit logic, and deterministic egress management to survive the Refactoring Cliff.
Level 100: VNet & Hybrid Connectivity
- • VNet Design: Implementing address space management and subnet segmentation.
- • NSG Logic: Managing Network Security Groups for granular traffic control.
- • ExpressRoute: Establishing dedicated private connections for predictable performance.
Architect’s Verdict: Hybrid success in Azure depends on a clean, routable VNet architecture.
Analyze VNet LogicLevel 200: Virtual WAN & Global Transit
- • vWAN Orchestration: Centralizing any-to-any connectivity across global hubs.
- • Hub-and-Spoke: Automating transit routing between peered VNets and branches.
- • Firewall Integration: Securing transit paths with Azure Firewall Manager.
Architect’s Verdict: Azure Virtual WAN is the required foundation for distributed hybrid enterprises.
Analyze vWAN LogicLevel 300: AKS & Service Mesh
- • AKS Networking: Comparing Azure CNI vs. Kubenet for high-density pod deployments.
- • Private Link: Securing PaaS access without exposing services to the public internet.
- • Service Mesh: Orchestrating mTLS and observability with Istio on AKS.
Architect’s Verdict: For Cloud-Native scale, Azure CNI is the only choice for deterministic pod routing.
Advanced AKS LogicValidation Tool: ExpressRoute Circuit Audit
Circuit VerifiedDeterministic performance in Azure requires a healthy physical layer. Use this audit tool to validate BGP session state, ARP table health, and circuit utilization across your ExpressRoute provider edge.
Azure Topology: vWAN vs. Hub-and-Spoke
| Metric | Virtual WAN (vWAN) | Traditional Hub-and-Spoke |
|---|---|---|
| Management | Managed Microsoft Service | User-Managed (Manual Peering) |
| Routing | Automated Any-to-Any | User-Defined Routes (UDRs) |
| Scale | Global / High-Density | Regional / Mid-Density |
Architect’s Verdict: Virtual WAN is the gold standard for global enterprises looking to eliminate the management overhead of complex UDR chains and manual VNet peering.
Level 300: Hybrid Cloud-Native
- Azure Arc Integration: Managing on-premises KVM/ESXi clusters as first-class citizens within the Azure Resource Manager (ARM) control plane.
- AKS Private Clusters: Implementing fully isolated Kubernetes control planes with private link access to avoid the public internet.
- Global Traffic Logic: Utilizing Azure Front Door and Traffic Manager to orchestrate failover between regional AKS clusters and on-premises endpoints.
Architect’s Verdict: Hybridity in Azure is about control plane unification. Use Arc to manage your sprawl before it manages you.
