Varnish Cache is an open source web application accelerator (also referred to as an HTTP accelerator or caching HTTP reverse proxy). Varnish stores (or caches) files or fragments of files in memory; this enables Varnish to reduce the response time and network bandwidth consumption on future, equivalent requests. Unlike web servers like Apache and nginx, Varnish was designed for use exclusively with the HTTP protocol. Magento 2 supports Varnish versions 3.0.5 or later or any Varnish 4.x version.
