Scaling Next.js to enterprise level requires moving beyond default configurations. Start with high-ROI wins like CDN implementation and vertical scaling, then progress to horizontal scaling with shared Redis caching to avoid cold cache problems across replicas. Implement API gateways for centralized authentication, use blob storage with signed URLs for file uploads, and adopt event-driven architecture for high-volume interactions. Optimize with HTTP/2 and gRPC for internal communication. Define SLAs/SLOs upfront, measure with monitoring and load testing, and iterate based on bottlenecks rather than adopting everything at once.
