Hello Rashmi,
Next.js is an open-source JavaScript framework based on React and developed by Vercel. It is therefore very well integrated to be deployed with Vercel.
There are roughly 2 modes of use of Next.js: - SSG (Static Site Generation) that can be deployed with our tool at ScaleDynamics as a Hosting module: https://scaledynamics.com/static-assets-hosting - SSR ( Server Side Rendering), the most used mode in my opinion and which can be deployed with ScaleDynamics as a Server module: https://scaledynamics.com/managed-nodejs-server
Vercel does not support Docker, nor Dedicated servers, only Serverless. https://vercel.com/support/articles/does-vercel-support-docker-deployments
Vercel is quite vague on the available resources (sometimes GCP, sometimes AWS it changes over time ...) https://vercel.com/docs/concepts/edge-network/regions#routing
We advise you to look at our Scaledynamics offer as well, because we offer dedicated (not serverless). Moreover, you can choose the resource and the cloud provider and move at any time.
Yours, Darin
