Learn Canary Deployment step-by-step with theory + real-world implementation using Node.js and Express.
In this video, I explain how companies deploy new features safely using 1% traffic routing strategy, reducing risk and ensuring zero downtime deployments.
You will learn:
✔ What is Canary Deployment
✔ Why it is used in production systems
✔ How 1% → 99% traffic splitting works
✔ Real implementation using Express Gateway
✔ Microservices routing (V1 vs V2)
✔ Payment service example (Razorpay vs Stripe)
We build a real gateway service that routes traffic:
99% → Old version (V1)
1% → New version (V2)
This is exactly how modern systems like Netflix, Amazon, and Google deploy updates safely.
