What are the ways to expand and increase the throughput of a web application?

To expand and increase the throughput of a web application in C#, the following approaches can be used:

• Scaling:

  • Horizontal — adding new servers (clustering, load balancing).
  • Vertical — increasing resources of the existing server (CPU, RAM).

• Caching:

  • Using cache at the application level (MemoryCache, Redis) to reduce database load.

• Code and query optimization:

  • Profiling and optimizing slow sections.
  • Using asynchronous methods (async/await) to improve responsiveness.

• Using CDN for static content.

• Load distribution:

  • Dividing the application into microservices.
  • Using message queues to handle heavy tasks in the background.

Example of using an asynchronous controller in ASP.NET Core:

[HttpGet]
public async Task<IActionResult> GetData()
{
    var data = await _service.GetDataAsync();
    return Ok(data);
}
