Azure APAC Latency Test — Workshop

Measure and compare WebSocket, HTTP, and Blob storage latency across 14 Azure regions in Asia-Pacific.

What You’ll Build

A latency measurement platform that:

• Deploys 14 VMs across APAC Azure regions with WebSocket echo servers
• Measures WebSocket RTT via persistent connections (port 8080)
• Measures HTTP ping via nginx HEAD requests (port 80)
• Measures Blob latency via Azure Storage static websites
• Visualizes results in an Angular dashboard with real-time charts

Architecture at a Glance

Component	Technology	Hosting
🖥️ Frontend	Angular	VM (Southeast Asia) or local
🔌 WebSocket Echo	Node.js + ws	B2s VM × 14 regions
🌐 HTTP Ping	nginx	B2s VM × 14 regions
📦 Blob Storage	Static Website	Storage Account × 14 regions
🛡️ Networking	NSG + Public IP	Per-region

Workshop Modules

#	Module	Duration	Description
1	Prerequisites	10 min	Set up your environment
2	Architecture	10 min	Understand the system design
3	Deploy Infrastructure	25 min	Provision VMs and storage
4	Run Latency Tests	15 min	Execute tests and collect data
5	Analyze Results	15 min	Interpret findings
6	Frontend Dashboard	20 min	Deploy the Angular UI
7	Cleanup	5 min	Destroy resources
8	Azure Visualizer Demo	20 min	Generate architecture diagrams with Copilot

Total estimated time: ~1.5 hours (+ 20 min optional visualizer demo)

Key Design Decisions

• Azure CLI over Bicep/Terraform — lower barrier for workshop attendees
• B2s over B1s — avoids CPU throttling on burstable VMs that inflates latency
• Idempotent scripts — ensure-vms-ready.sh handles create, start, and NSG in one pass
• Multiple measurement types — WebSocket (persistent), HTTP (request/response), Blob (storage layer)
• 14 APAC regions — comprehensive coverage including new regions (Indonesia, Malaysia)

This workshop targets APAC regions. GPU or premium SKUs are not required.
