Vercel for speed, Docker for scale
Joe Zeng, software engineer at Statsig, on using Docker
Vercel wins when shipping speed matters more than infrastructure control. For a small team building a Next.js app, it turns deploy, hosting, CDN, serverless functions, and routing into one workflow, so a front end engineer can push code and get a live site without stitching together Docker, Kubernetes, cloud networking, and CI. Docker plus Kubernetes still matters once bandwidth, customization, or internal platform requirements become the real constraint.
-
The real product is not raw infrastructure, it is preassembled workflow. Vercel and Netlify package storage, compute, CDN, and deploy tooling so developers do not have to provision clusters or manage separate services just to launch a web app.
-
The main breakpoint is scale and control. Prior research found these platforms can cost materially more on bandwidth than going direct to cloud infrastructure, which is why startups start there, but larger companies often move more workloads onto AWS or their own stack.
-
Docker and Kubernetes still have an advantage for teams like Statsig that run backend APIs, event pipelines, and stateful services across cloud environments. Containers are portable, lightweight, and fit multi service systems better than an opinionated frontend hosting platform.
The direction of travel is toward hybrid stacks. More projects will start on Vercel because the first deploy is easier, while larger apps will keep pulling in containers, custom infra, and in house platforms as they add traffic, security needs, and more complex backends. The winning platforms will blur that line by keeping Vercel level simplicity while adding more control.
