Balances loads efficiently and saves costs but could improve initial setup
The typical use case for Barracuda Load Balancer ADC involves managing and distributing network traffic efficiently to maintain system performance. Clients use Barracuda Load Balancer ADC for its ability to handle and balance loads across servers I have seen improvements in Barracuda Load…

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.

Quotes from Members

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

Pros

"The most useful features in Barracuda Load Balancer are its security capabilities, load balancing efficiency, and scalability."
"The initial setup was straightforward and deployment took one day."
"I would rate the stability of Barracuda Load Balancer as a ten out of ten; it has high stability."
"The solution is simple and powerful. I find the Barracuda Load Balancer ADC's load balancing function most valuable. It balances the traffic well. The security features, like the Web Application Firewall, are also very helpful."
"The price is very good, and it's not very expensive."
"The Barracuda solution has improved the way we function by consolidating threat management and network optimization in one standalone appliance."
"Barracuda's technical support is good - whenever we have an issue, they immediately connect and resolve it."
"Performance configuration options with threads, processes, and core stickiness are very valuable."
"It solves a problem for me where I can build files, not based on the health of the check, but rather the speed of the check."
"I can simplify configurations of many internal services (e.g. Web server configs) by moving some elements (like SSL) to HAProxy. I can also disable additional applications, like Varnish, by moving traffic shaping configurations to HAProxy."
"The ease of use of the configuration, and great documentation, are the most valuable features for us."
"The support for all major Linux distros makes running and testing a breeze."
"I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring."
"It is stable. Period. Will not fail unless you do something wrong."
"I have found HAProxy very helpful in replicating production environment architecture in a development and testing environment."
 

Cons

"The quality of the solution's performance could be improved."
"We find with WAN optimization it’s a bit unstable but we don't use it for that."
"The Barracuda Load Balancer ADC could be improved with more customization features. For example, F5 uses iRules for custom configurations. I haven't found something similar in Barracuda yet. The load balancer and WAF's basic and common features are enough, but we need more customization options."
"Load Balancer ADC is competitively priced, but it's not feature-rich, and its technology is not that advanced."
"There are areas of Barracuda Load Balancer's security that have room for improvement, particularly concerning handling traffic."
"HAProxy is definitely a power-user tool. It is enormously scalable and flexible, but this can come at the cost of usability."
"The product does not have any new technologies."
"The logging functionality could use improvement, as it is a little cryptic."
"Also, having multiple HAProxy nodes in High Availability mode requires the use of clustering software such as Pacemaker and Corosync which are very complex."
"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."
"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."
"There is room for improvement in the pricing model. It could be cheaper."
"From my point of view, the configuration should be more friendly, perhaps with a Web interface."
 

Pricing and Cost Advice

"Load Balancer ADC is cost-effective and is about half the price of F5."
"I rate the solution's pricing a five out of ten."
"The price is well worth it. HAProxy Enterprise Edition paid for itself within months, simply due to the resiliency it brings. It was a bit more expensive than we were originally interested in paying, but we are thankful we chose to go with HAProxy."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
"We are using HAProxy as an open-source."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"It is free of cost."
"HAProxy is an open-source solution."
"HAProxy is free in the initial offer. However, pricing can be improved."
"The licensing fee for the solution is $690 per unit annually."
