Releasing safe and cost-efficient blue-green deployments

This post details how Vercel's platform primitives (Skew Protection, Edge Config, Middleware) and serverless architecture enable cost-efficient and scalable blue-green deployments. It highlights how immutable deployments and the absence of duplicated infrastructure reduce overhead and costs compared to traditional Kubernetes-based approaches. It also introduces multicolor and shadow rollout strategies as extensions of blue-green deployments.
