Azure Virtual Network Skill

This skill provides expert guidance for Azure Virtual Network. Covers best practices, decision making, architecture & design patterns, limits & quotas, security, configuration, and deployment. It combines local quick-reference content with remote documentation fetching capabilities.

How to Use This Skill

IMPORTANT for Agent: Use the Category Index below to locate relevant sections. For categories with line ranges (e.g., L35-L120), use read_file with the specified lines. For categories with file links (e.g., [security.md](security.md)), use read_file on the linked reference file

IMPORTANT for Agent: If metadata.generated_at is more than 3 months old, suggest the user pull the latest version from the repository. If mcp_microsoftdocs tools are not available, suggest the user install it: Installation Guide

This skill requires network access to fetch documentation content:

Preferred: Use mcp_microsoftdocs:microsoft_docs_fetch with query string from=learn-agent-skill. Returns Markdown.
Fallback: Use fetch_webpage with query string from=learn-agent-skill&accept=text/markdown. Returns Markdown.

Category Index

Category	Lines	Description
Best Practices	L35-L43	Designing secure, high-performance VNets: NSG rule patterns, traffic flow, VM throughput tuning, TCP/IP optimization, and secure use of VNet service endpoints.
Decision Making	L44-L53	Guidance on choosing VNet-related options: MANA support for VM sizes, upgrading Basic to Standard public IPs, routing preference and unmetered CDN traffic, cost trade-offs, and VNet integration for isolation.
Architecture & Design Patterns	L54-L60	Designing VNet architectures: subnet extension for migrations, VNet peering, hybrid two-tier apps, traffic mirroring with TAP, topology planning, and custom routing options.
Limits & Quotas	L61-L68	Network resource limits and behaviors for Azure VMs/VNets: accelerated networking support, public IP quotas, VM throughput caps, and Virtual Network scale/performance constraints.
Security	L69-L78	Securing Virtual Networks: network policies, encryption, service tags, service endpoint policies, and applying Azure Policy/security controls to VNets and Kubernetes traffic.
Configuration	L79-L114	Configuring Azure VNets: IPs (public/private, prefixes, IPv4/IPv6), DNS, MTU, DHCP, subnet delegation/peering, monitoring, and CNI/MANA networking for VMs, NVAs, Kubernetes, and PaaS.
Deployment	L115-L118	Guidance for upgrading Azure Basic public IP addresses to Standard SKU, including requirements, steps, and considerations for network resources and downtime.
