From our experience, the most popular are definitely Netlify and Vercel. We don't have a lot of cases where we are forced to use AWS or Azure. I'm not sure how it looks like in general, but that has been our experience. In some cases, we have even migrated from Amazon to Netlify. But the other way, not yet.
Netlify is a hosting and serverless backend platform for web applications.
Vercel is a cloud platform for deploying Jamstack websites and web services.
