Enterprise Jamstack Tradeoffs and Shift
Jamund Ferguson, senior engineer at PayPal, on using Jamstack in the enterprise
This is the core tradeoff that pushed enterprise teams past pure Jamstack, developer speed improved, but user speed often got worse. In a personalized product, the CDN can only send the shell of the page. The real content still has to come from an API after the browser loads. That means users first see empty boxes, then spinners, then data, which is exactly the delay Amazon teams spent time trying to remove with more server rendering and edge execution.

This pattern works best for marketing sites, blogs, and other pages where content changes slowly. It breaks down when every page is custom to the logged in user, because the browser has to assemble the page after load instead of receiving finished HTML up front.
-
The reason developers still loved it was workflow. Static apps and APIs could be deployed separately, front end engineers did not need to manage servers, and platforms like Vercel turned backend endpoints into simple functions sitting beside UI code in the same project.
-
Next.js became important because it let teams mix approaches page by page. A team could keep the easy component based workflow of Jamstack, but server render the first view when latency or personalization made client side fetching feel slow.
The direction of travel is toward hybrid and edge rendering. The winning setup keeps the easy Git based developer workflow, but moves more of the first page render closer to the user so personalized apps can load with real content immediately instead of painting a skeleton and waiting on APIs.
