The definition of production quality
What do you like best about the product?
Code base originated from and authored by BSD kernel developers implies uncompromised quality and attention to code correctness. Like BSD, Varnish may not always have the latest features but what is released is always 100% rock solid, battle hardened and trustworthy for any size production workload.
What do you dislike about the product?
The threading model is a bit dated and difficult to tune, compared to competing per-core event loop models. Also the commercial product is slow to release it's improvements back to the community version.
What problems is the product solving and how is that benefiting you?
Cost savings by reducing traffic to back-end and less reliance on expensive cloud services. Zero downtime deployments. Real-time statistics on the performance of the back-end services. VCL and VMODs are great for implementing efficient workarounds for bugs in legacy back-end applications that cannot be easily changed.
Recommendations to others considering the product:
It is a product that is easy to use but difficult to master. Consider hiring an expert to avoid configuration pitfalls. Money well spent.
Refinitiv Reverse Proxy
What do you like best about the product?
the performence, the flexibility of configuration vith VCL, testing with VTC, the vmods
What do you dislike about the product?
TLS not supported on the backend side in the opensource version.
What problems is the product solving and how is that benefiting you?
Reverse Proxy used as a gateway to 100s of background services. This lead to a huge vcl configuration with 1000s of routing rules...
Recommendations to others considering the product:
Take the Varnish Plus.
Essential website architecture component
What do you like best about the product?
Stable and resilient, amazing speedy HTTP answers
What do you dislike about the product?
HTTPS is not "out of the box" supported. Currently HTTPS is a must have for any website, the hitch implementation should be varnish embedded
Lack of complexed and current VCL examples
Some modules seem pretty new and need a lot of work to be used (like WAF, API protection, ...)
Varnish application enhancements and new functionnalities and module are hidden in sub minors updates (like new resolver module in 6.0.6-R8 ?!?!?! headerplus in 6.0.6-R6 ?! why not a 6.X ?)
Documentation is shared between the opensource project, varnish software blogs, and varnish software release notes varnish software wiki and varnish software documentation. Infrequent update of the varnish book.

Speed Speed Speed
What do you like best about the product?
The website world grows more competitive every day. Varnish is a simple way to set your site apart from the majority of sites out there. This aggressive caching machine helps take your site speed to the next level. Anyone who fights for search engine rankings knows even the smallest leg up on the sites above you can help. Site speed matters in 2020 and Varnish Cache gives you just that.
What do you dislike about the product?
The caching is quite aggressive. This is not the easiest install. The devs at Varnish are fantastic and will work with you to get it all configured, but you will definitely need an experienced developer on your team to work hand in hand with them to get this installed. You will also likely have to make some changes on your site to accommodate for this aggressive cache
What problems is the product solving and how is that benefiting you?
Site speed. Search Engine Rankings. Take your site to the top level. Multi-million dollar web apps use Varnish, there is a reason for that. It is one of the most aggressive caching systems out there but one of the most important features your site must-have if you are looking to have your website running at peak performance.
Recommendations to others considering the product:
If you are looking to speed your site up, to match what most industry leaders are doing, Varnish is the ticket.
Varnish usage at MTG
What do you like best about the product?
The responsiveness and knowledge of the support guys. The thoroughness and technical details of their replies. The reply speed and the desire to help with various examples.
What do you dislike about the product?
The lack of pre build scripts in Terraform or Cloudformation to raise a Varnish Cluster
What problems is the product solving and how is that benefiting you?
Caching of multiple websites by using a Varnish cluster with a single load balancer as entry point, VCL as management of the caching settings and of the backends and multiple internal load balancers, each covering a different website with different traffic patterns, all served by a single cluster of 3 Varnish servers managed by the VCAdmin interface.
Recommendations to others considering the product:
Take your time to understand and build a proper cluster, it will work flawlessly after that.
