"Performance, Quality, Configuration"

4.5/5

What do you like best about Varnish Software?

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.

I use varnish for caching popular content (VOD, Live, Static Assets) on hundred of servers, but also for Load Balancing API. Varnish support also distributed and multi-level of caching.

I haven't found any problems in many years. The support is fast, and helpfull. The support come from the developper so it's very easy to find issue with our hardware. Review collected by and hosted on G2.com.

What do you dislike about Varnish Software?

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.

What problems is Varnish Software solving and how is that benefiting you?

Varnish can serve without a flaw severall hundred tv channels, and thousand of VOD contents to our customers. Caching severall terabytes of content is not a easy task, varnish solve it with distribute caching and load-balancing between healthy node. Scaling is not a problem, we just need to increase the number of servers. Review collected by and hosted on G2.com.

"Varnish Software: A Simple Review"

4/5

What do you like best about Varnish Software?

The Cache HA Cluster and ESI (Edge Side Includes) features are often considered among the best aspects of Varnish Software due to their capability to optimize web performance and manage content delivery efficiently. Review collected by and hosted on G2.com.

What do you dislike about Varnish Software?

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.

What problems is Varnish Software solving and how is that benefiting you?

Varnish Software solves several problems by providing efficient solutions for content distribution and backend system connections. The use of Edge Side Includes (ESI) allows for server-side distribution of systems without disrupting the frontend. This approach enables efficient content delivery using client-side connections to various backend systems. This benefits us by enhancing performance and maintaining a seamless experience, as the distribution happens effectively at the edge, optimizing the overall system architecture.

The only minor drawbacks I can think of are related to the aggressive caching approach. This approach sometimes requires custom code to make it suitable for automatic cache invalidation using cache tags. Review collected by and hosted on G2.com.

"Value adding component, securing end user experience and cost efficient"

5/5

What do you like best about Varnish Software?

It is flexible, securing our web development from request to response from client to backend and back again. Cost efficient, fast load to clients, low usage of backend infrastructure. High availability. Review collected by and hosted on G2.com.

What do you dislike about Varnish Software?

Very hard to say anything less good about Varnish. It's a technical product, built by technical people for technical usage, But make everyone happy from technicians to end users. One thing is that is so in front line of services to manage subscription thats its harder for a large company with security regulations to manage installation media and patches, but that problem is more on our side rather than problem with Varnish.
