Handles high traffic efficiently and simplifies complex routing with rule-based logic

I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.

A solution requiring straightforward maintenance while remaining cost-effective compared to its competitors in the market

I am not in a position to speak about the areas where the solution needed improvement because I resigned during the implementation phase. At that time, the implementation was ongoing, and everything seemed to be going well. Using the solution, our team managed to transfer a couple of routers through a few areas. However, I believe the migration is still ongoing. Nonetheless, the first phase of the implementation was successful before my departure. There was a certain level of performance degradation in the solution, which I don't know if it can be tuned. This is because I was working for a short period on the solution. In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution. If one wants to scale up, then one needs to change their plan. However, the thing is, one can always go for the larger scale based on one's anticipation of future traffic.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"It reduced the load on our main load balancers."

"I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring."

"The solution is effective in managing our traffic."

"Overall, it's a good solution."

"The features I find valuable in this solution are session control which automatically disconnects users that forget to log off, and the ability to write rules to either allow or block certain file requests."

"We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host."

"Reliability. HAProxy is the most reliable product I have ever used."

"Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind."

More HAProxy pros

"The managed service allows us to confidently rely on Nexusguard’s professional team to take relevant actions as and when required to make sure DDoS attacks are successfully mitigated, ensuring 100% uptime of our service."

"Based on the support received for implementation, I rate the solution's technical support a nine out of ten."

"Nexusguard has given us confidence that we are protected against any outside attacks."

"Nexusguard has exponentially improved the availability of our services because we don't have to worry much about any threats or DDoS attacks towards our services."

"The support team was helpful."

"Cloud Diversion is another good feature packaged with the whole solution. When attack traffic is detected, Cloud Diversion triggers to automatically route our prefix to Nexusguard’s scrubbing center, ensuring that all attack traffic is dropped in the shortest time possible."

"Filters can be customized depending on the characteristics of the attack traffic. This feature has made it easier for Nexusguard's SOC team to further isolate any specific attack that can't be blocked by pre-configured mitigation."

Cons

"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."

"It needs proper HTTP/2 support."

"I would like to evaluate load-balancing algorithms other than round robin and SSL offloading."

"Dynamic update API. More things should be possible to be configured during runtime."

"In my previous job we had some stability issues related to configuration and compatibility with other products."

"While the product is quite perfect, it could use more supervision and be more active. Also, more simplicity, more peripherals, and more scalability."

"There is room for improvement in the pricing model. It could be cheaper."

"The basic clustering is not usable in our very specific setup."

More HAProxy cons

"One thing that we would like to improve from them is to provide more training to SOC team for them to have a deep understanding of the solution so that they would always be ready to answer anything without the need to escalate queries to senior personnel."

"There was a certain level of performance degradation in the solution, which I don't know if it can be tuned...In my experience, it is an area that can be improved while also considering the stability and scalability aspects of the solution."

"One of the features that should be added to the next release is report generation. Currently, reports can be downloaded every month and are only available at the beginning of each month. It would be nice to generate the reports based on specific dates that we prefer and not have to wait until the next month for the current month’s report."

"The solution must provide features for the post-processing of the traffic type and the traffic quality."

"The mitigation scope of Origin Protection is not fully efficient as there could be delays in activating the countermeasures."

"One of the features that should be added to the next release is report generation."

Pricing and Cost Advice

"HAProxy is free in the initial offer. However, pricing can be improved."

"It is free of cost."

"When it comes to pricing HAProxy is free."

"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."

"I use the open-source version of the product. I don't have experience with the licensed version of the solution."

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."

"HAProxy is a free open-source solution."

"Very good value for the money. One of the simplest licensing schemes in this category of products."

More HAProxy pricing and cost advice

"On a scale of one to ten, where one represents a cheap option, and ten represents an expensive option, I would rate the solution a seven in terms of cost."
