Kestrel web server vs iis. Kestrel can be used by itself or with a reverse proxy server such as Internet Information Services IIS Nginx or Apache. IIS has SSL certificates. It is run behind IIS using the HttpPlatformHandler.

The Kestrel web server is a new web server as part of ASPNET Core. It is intended to be used in production for ASPNET 5. This report shows the usage statistics of Apache vs.

Kestrel is considered a preferred web server for newer ASPNET applications see this post for a comparison to IIS and why you need both. It is now the. IIS web servers have HTTP access logs which is not the case in kestrel.

IIS allows port sharingmultiple apps running at the same time while kestrel doesnt. Better performance and memory utilization. Built to be very fast and it is Kestrel is built to be fast.

It is recommended that you run it behind a more fully featured webserver like IIS on Windows or NGNIX on Linux. But when I run my website I still get the IIS Express icon in the system tray. Comparison of both the servers IIS web server only supports Windows while kestrel web server supports all platforms.

Kestrel itself can be run from the command line but therein lies the issue where you often have to set up your application as a Windows Service More info here. Some features of Kestrel Kestrel does not support multiple applications sharing same port similar to IIS where applications are differentiated by host header value.

Just quickly anecdotally the management of IIS is much easier than managing a range of Kestrel web services. Programmatic port and TLS configuration. If deploying on Linux you should run a comparable reverse proxy server such as Apache or Nginx to proxy requests to Kestrel.

It is based on the libuv library the same one used by nodejs. All requests from IIS are actually passed one on one to the Kestrel web server hosted inside dotnetexe. Libuv supports an event-driven style of programming.

The ASPNET Core Module is a native IIS module that handles native IIS requests between IIS and the in-process IIS HTTP Server or Kestrel. Microsoft suggests you also use a full featured server and reverse proxy to Kestrel for most applications. Our reports are updated daily.

If you intend to deploy your application on a Windows server you should run IIS as a reverse proxy server that manages and proxies requests to Kestrel. I come from developing apps on IIS Express and hosting them on an IIS web server. A reverse proxy server receives HTTP requests from the network and forwards them to Kestrel.

One thing we learned is different is how IIS handles things. The request that reaches IIS on port 80443 is packaged up into an HTTPContext kind of object and passed on to Kestrel web server. It is designed to run behind a proxy like IIS on windows or NGINX on LinuxMacOS and should not be used to directly host ASPNET Core or any other application in production environments.

Comparison of Kestrel Web Server Vs IIS IIS can perform anything which is required to run ASPNET Core application whereas Kestrel uses as little as required because of this Kestrel server execution is much faster than IIS.
