How do you design AngularJS architecture for millions of concurrent users?

Massive-scale AngularJS apps rely on stateless frontend design, CDN delivery, and minimal client computation.

Supporting millions of users requires minimizing frontend workload. AngularJS must be used as a thin presentation layer with heavy reliance on backend APIs. Static assets are served via CDN, and state is kept minimal on client side. Digest cycles are optimized aggressively, and real-time updates are throttled. Architecture must assume frontend is disposable and stateless.
