Varnish Enterprise 6 (Ubuntu)

Varnish Enterprise  is primarily used by my organization to cache responses for quick suggestions for users. For example, when users visit IndiaMART and start typing in the search box, we show them a list of suggestions to choose from, which is the module I work on—the suggest module. The request goes through Varnish, and if the request is already present in Varnish, we provide the response back immediately. If it is not there, we proceed to hit the back end servers.

Varnish Enterprise  is also used by my organization as a load balancer.

The best features Varnish Enterprise offers are the caching and the load balancing, which are the two main use cases for my organization.

Varnish Enterprise stands out because it can be used to trim down the URL noise, which is really helpful in maintaining a very discreet cache. If users have different parameters but type one letter, they can all be shown the same suggestions regardless of their name or location. This has helped tremendously in cutting down the URL noise and has improved search traceability, aiding in investigating issues.

Varnish Enterprise has positively impacted my organization by significantly reducing the API latency for my personal use case, and the same applies to other teams who use it.

I am not sure how Varnish Enterprise can be improved. I will have to delve deeper into the technicalities that I am not yet familiar with, so this is a question I am not equipped enough to answer.

Since I moved to back end, I have been in regular touch with Varnish Enterprise for around one and a half years. Before that, I had a slight idea about what Varnish was. For hands-on implementation, it has been around one and a half years.

Varnish Enterprise is stable.

Varnish Enterprise's scalability is good, convenient, and reliable.

I have not had the opportunity to connect with customer support for Varnish Enterprise yet.

I have always been using Varnish Enterprise for caching. I did not use a different solution before.

I have not seen a return on investment with Varnish Enterprise.

I do not think I evaluated other options before choosing Varnish Enterprise.

The reduction in latency with Varnish Enterprise has affected business outcomes positively because the conversion rate of search for the suggestions shown to users has been significantly higher than for the search pages they land on by manually typing out the whole query. This is a clear conversion rate and is the KPI we always aim to improve.

My advice for others looking into using Varnish Enterprise is to make sure that it justifies their use case and that it is not an overkill or an underkill for their particular requirement. I would rate this review an eight out of ten.

My main use case for Varnish Enterprise  was to provide speed improvements for websites that we were creating for our clients through a SaaS service, which was a no-code website builder. We wanted to have Varnish Enterprise  as a caching layer in between.

This specific example was part of the website builder itself. When people created their own websites, they were hosted in our system and served through the Varnish Enterprise layer, functioning as a private CDN . We had servers closer to user locations from which we served these websites. Before and after implementation, there was a marked difference in the speed of the systems, and the users noticed it as well. There was significant improvement in the user experience.

The best features of Varnish Enterprise include caching performance, which I believe is best in its class and was the main reason we selected it. Varnish Enterprise offers more granular control on the cache and cache control, allowing us to fine-tune the caching behavior and route traffic in a custom way. The cache control and invalidation logic enabled us to purge requests instantly, which was valuable.

Varnish Enterprise has impacted my organization positively by showing marked improvement in the speed at which websites were being served. The clients were happy with that, and the people who owned or created those websites were satisfied. This had a positive impact, as we likely had more revenue as a result.

Varnish Enterprise can be improved, particularly on the security features, as it does not differentiate itself compared to Cloudflare  because it only provides the usual TLS termination and load balancing capabilities. If there is an area where it can improve itself, it would be on the security side.

Mutual TLS termination is something I wish was included. I have not used Varnish Enterprise for the last three years, so I cannot confirm whether this feature is now included, but at the time we were using it, we did not see that feature.

I am not using Varnish Enterprise currently, but in my previous organization, I used it for around eighteen months.

I do not recall the exact revenue figures, but the speed improvement was significant. It was at least a forty percent improvement in the speed at which websites loaded, which was great.

We implemented Varnish Enterprise by using the Helm charts that Varnish provides in the backend. It has been around three years since we did this implementation, so the exact details are a bit unclear, but I do remember the impact of it. We evaluated it against other solutions, including Fastly  and Cloudflare , and Varnish Enterprise served us well.

I would rate Varnish Enterprise at least eight out of ten.

I chose eight out of ten because the product needs to work on the security part of things. Additionally, while it does give a lot of granular control, it requires a lot of effort to achieve those controls. There was considerable effort from our side to achieve those granular controls on the caching logic, invalidation, and other aspects. If those could be easier to accomplish, I would give it a ten.

Regarding Varnish Enterprise's AI capabilities, I used it three years ago, and there were not many AI capabilities at that point in time, so I cannot comment on this. I did not have any experience with Varnish Enterprise's AI capabilities regarding the accuracy and reliability of output.

Varnish Enterprise is a great product because the core part works very well, achieving speed and cache validation, invalidation, and control logic. If those looking for these particular features, it is a great product. I have not seen the updated product and have not used it in the last couple of years, so I do not have any other thoughts.

My overall rating for Varnish Enterprise is eight out of ten.

My main use case for Varnish Enterprise  is mostly cache. When I say mostly cache, I mean we get directly into Varnish and we edit the rules with VCL files.

In my opinion, the best features Varnish Enterprise  offers are excellent. What makes those features stand out for me is the flexibility and configuration options because we can edit mostly everything about the request and a specific response for a specific request.

Varnish Enterprise has positively impacted my organization because the response time is an upgrade. The improved response time has benefited my organization as the response time for HTTP requests is more efficient and quick.

I think Varnish Enterprise can be improved as the prices can be cheaper. Besides the price, I do not think there is anything else that could be better.

I have been using Varnish Enterprise for about three years.

My experience with pricing, setup cost, and licensing is difficult as some clients do not want to pay so much.

I do not want to add anything else about the features. The price and the feasibility of implementation keep Varnish Enterprise from being a perfect ten for me. I rate Varnish Enterprise overall as an eight out of ten.
