How does .NET Core handle load balancing strategies?

Updated Apr 28, 2026

Short answer

.NET Core supports load balancing through reverse proxies, distributed hosting, service discovery, and traffic distribution strategies such as round-robin, least connections, and health-based routing.

Deep explanation

Load balancing distributes incoming traffic across multiple application instances to improve:

  • Scalability
  • Availability
  • Fault tolerance
  • Performance

ASP.NET Core itself does not directly perform load balancing internally. Instead, it works with infrastructure and middleware that support load balancing.

Common technologies include:

  • NGINX
  • HAProxy
  • Microsoft Azure Load Balancer
  • Amazon Web Services Elastic Load Balancer
  • YARP
