🆚 Application Request Routing vs. Varnish

Application Request Routing is a module for Internet Information Server (IIS) that can load-balance between multiple servers in a server farm.

Varnish Cache is an open-source HTTP accelerator and reverse caching proxy that caches content from web servers to reduce load times, and supports native TLS termination and Kubernetes deployments.

It uses the VCL configuration language compiled to native C code, serves cached responses in three system calls, provides official container images and a Helm chart for Kubernetes, outputs structured JSON logs, and supports VMOD extension modules.
