To scale .NET Core applications in high-traffic environments, implement caching mechanisms and load balancing strategies. Utilize response caching to store rendered HTML or API responses temporarily, reducing server workload. Implement distributed cache using Redis or SQL Server for shared data across instances.
For load balancing, use round-robin DNS or a dedicated load balancer like Azure Load Balancer. Employ sticky sessions to maintain user state during navigation. Consider horizontal scaling by adding more application instances and vertical scaling through increased resources on existing instances.
Optimize performance with asynchronous programming, minimizing blocking calls, and leveraging parallelism. Monitor application metrics to identify bottlenecks and adjust accordingly.
