Multi-Zones are best suited for large-scale enterprise applications where unrelated domains (like a marketing site vs. a customer dashboard) can be managed by independent teams, and for incrementally migrating legacy systems.
Large-Scale Enterprise Applications: Ideal for complex apps where sections like marketing, documentation, blog, and authenticated dashboard are logically distinct and can be owned by separate teams[citation:1][citation:6].
Incremental Migration: Modernizing a legacy monolithic application. You can create a new zone for new features while keeping the old site in a legacy zone, serving both under the same domain until migration is complete[citation:1].
Organizational Structure Alignment: In large organizations, teams can be mapped directly to zones, granting them full ownership over their domain's code, dependencies, and deployment lifecycle[citation:6].

Technology-Agnostic Systems: When different parts of a platform are best built with different frameworks or versions of Next.js (e.g., a real-time dashboard using WebSockets vs. a static marketing site)[citation:1].
Scalability & Build Time Optimization: When a monorepo or a single application becomes too large, causing slow builds. Isolating heavy parts (like a documentation site) into a separate zone prevents it from slowing down development on the main app[citation:1][citation:10].
