Varnish is really fast and powerfull . The Varnish Configuration Langage (VCL) is a must (think embedding Javascript to configure the cache). You can do everything with it.

It's difficult to find a flaw for Varnish. Perhaps the cost of the solution ? But when i see the number of times i've open a ticket (3 in 8 years) I think the value is well spent. Review collected by and hosted on G2.com.

One drawback of Varnish Software is the lack of native support for Kubernetes as an ingress controller. While Varnish offers advanced routing, caching, and other features, its compatibility with Kubernetes and cncf solutions is limited, which can hinder its seamless integration within Kubernetes environments. This limitation could potentially be addressed to broaden the software's usage. Review collected by and hosted on G2.com.
