Building across a single cloud is useful, but building across three clouds teaches a different level of operational thinking. In this lab, you create a working multi-cloud setup where a centralized load balancer distributes live traffic across web servers running in AWS, Microsoft Azure, and Google Cloud.
This isn’t just theory—by the end, you’ll have hands-on experience with the same vendor-independent architecture that large enterprises use to avoid lock-in and maximize resilience.
Why Multi-Cloud Load Balancing Matters
Organizations are increasingly moving away from single-vendor strategies. Multi-cloud architectures provide:
- Vendor independence — No single provider controls your entire infrastructure
- High availability — Automatic failover if one cloud provider has an outage
- Cost optimization — Leverage competitive pricing across providers
- Geographic distribution — Deploy closer to users worldwide
What This Lab Covers
This hands-on lab walks you through building a complete multi-cloud environment:
- Deploy Ubuntu web servers in AWS, Azure, and Google Cloud
- Configure NGINX as a centralized reverse-proxy load balancer
- Set up health checks for automatic failover
- Test live traffic distribution across all three clouds
- Simulate provider outages and verify resilience
Lab Architecture Overview
The architecture is straightforward but powerful:
- Three backend web servers — One in each cloud provider, all running Ubuntu 22.04 with NGINX
- One load balancer — A dedicated Ubuntu VM running NGINX as a reverse proxy
- Single entry point — All traffic flows through the load balancer, which distributes requests
- Health monitoring — Unhealthy backends are automatically removed from rotation
What You’ll Learn
This lab gives you practical experience with:
- Cloud platform fundamentals — Work with AWS EC2, Azure VMs, and GCP Compute Engine
- Load balancing concepts — Understand upstream pools, health checks, and failover
- NGINX configuration — Set up reverse proxy and load distribution
- High availability testing — Simulate outages and verify automatic recovery
- Multi-cloud networking — Connect services across different providers
Perfect For
- Cloud architects designing multi-cloud solutions
- DevOps engineers implementing resilient infrastructure
- System administrators expanding their cloud skills
- Anyone preparing for AWS, Azure, or Google Cloud certifications
- Students learning enterprise architecture patterns
