You install it in front of any server that speaks HTTP and configure it to cache the contents. Varnish Cache is really, really fast. It typically speeds up delivery with a factor of 300 - 1000x, depending on your architecture. ## Varnish Cache Reviews ### 1. This is the single technology that keeps our website up **Rating:** 5.0/5.0 stars **Reviewed by:** Verified User in Higher Education | Mid-Market (51-1000 emp.) **Reviewed Date:** August 15, 2023 **What do you like best about Varnish Cache?** The amount of connections this will handle is massive. The configuration allows you to apply extremely granular control over when to use what backend, how long to cache something, and any number of routing considerations. **What do you dislike about Varnish Cache?** The configuration allows complete customization, with that it is also easy to shoot yourself in the foot. But running on Linux, most of us are accustomed to various foot-guns anyway, so I would say it's no different than anything else really. **What problems is Varnish Cache solving and how is that benefiting you?** Shields our backend servers from having to process PHP code constantly, becuase much of the content can be rendered once per day and served from cache. We also have "saint" configuration which will keep the site up even when the backend servers are non-responsive and as long as there is a cached version (even it it would have expired) will still serve content which adds to our uptime. ### 2.
