As enterprises mature in their CI/CD journey, they tend to ship code faster, safely, and securely. One essential strategy the DevOps team applies is releasing code progressively to production, also known as canary deployment. Canary deployment is a bulletproof mechanism that safely releases application changes and provides flexibility for business experiments. It can be implemented using open-source software like Argo Rollouts and Flagger. However, advanced DevOps teams want to gain granular control over their traffic and pod scaling while performing canary deployment to reduce overall costs. Many enterprises achieve advanced traffic management of canary deployment at scale using open-source Istio service mesh. We want to share our knowledge with the DevOps community through this blog. 

Before we get started, let us discuss the canary architecture implemented by Argo Rollouts and Istio.
