What is cell-based architecture?

It's partitioning apps into isolated cells — each self-sufficient for user subsets — to contain failures and scale independently.

How does cell-based architecture handle high traffic like Black Friday?

Routers direct traffic to healthy cells via hashing; sticky assignment keeps data local, preventing cascades.

Is cell-based architecture suitable for all applications?

Best for e-commerce, SaaS, social; trade-offs like eventual consistency nix it for strict ACID needs.
