Mehdi El Filahi - PeerSpot reviewer
Useful for for small and quick load-balancing tasks
What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks. The reliability features of HAProxy were particularly useful in a scenario where I needed to test load balancing between two Tomcats. Since these domains were inaccessible, I set up a third Docker with HAProxy, which had access to the Tomcat domains. I then configured HAProxy to handle the load balancing. This setup allowed the client to interact with HAProxy. The solution's integration with other elements is easy.

A tool for centralized management including inventory and sales tracking
Citrix ADM has the ability to implement policies to tighten security. For instance, you can restrict access to your network from outsiders or lack necessary security measures such as antivirus programs. Additionally, there's the Delivery Controller, which allows for comprehensive monitoring and management tasks such as remote restarts, maintenance, and registration. Another essential component is the Director, which provides detailed insights into sessions, including identifying session failures, connection issues, user lockouts, etc. It presents a list of problems to address, enabling you to click on them and resolve them efficiently.

Quotes from Members

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

Pros

"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."
"Stability is number one."
"The support for all major Linux distros makes running and testing a breeze."
"We don't have a problem with the user interface. it's good."
"We did not need technical support because the documentation is good."
"It is stable. Period. Will not fail unless you do something wrong."
"I can't speak to all of the HAProxy features because we don't use them all, but load balancing is very good."
"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 web application firewall which protects our services on the internet, and then of course services like our ability to provide high availability for the services we are offering are the most valuable features."
"The work balancing applications are the most valuable feature."
"If you need PCI-compliance and have high security requirements, WAF is the most valuable feature. If you need to monitor your load-balancing services with complex types of monitoring, make sure everything is alright, and load balancing is important, Content Switching and Monitoring features are the keys to your needs. If you want to provide a lot of static images or data, the Caching feature works best for you."
"I prefer this solution because of its user-friendly interface. I find it simple and close to what I am currently using, which is Citrix Fortiva Access for Multi-Factor Authentication. I appreciate the familiar user interface and troubleshooting tools it offers."
"My clients use it for load balancing."
"The solution was very easy to deploy."
"We use the product for load balancing and as a reverse proxy solution."
"The solution can be configured very granularly and has good control over security."
 

Cons

"​It needs proper HTTP/2 support.​"
"HAProxy is very weak in the logging and monitoring part and requires improvement."
"While troubleshooting, we are having some difficulties. There are no issues when it is running; it is stable and very good; however, if there is a troubleshooting issue or an incident occurs, we will have issues because this is open-source."
"There is no standardized document available. So, any individual has to work from scratch to work it out. If some standard deployment details are available, it would be helpful for people while deploying it. There should be more documentation on the standard deployment."
"We've changed solutions as it doesn't fit with our current needs."
"Documentation could be improved."
"Pricing, monitoring, and reports can be improved."
"There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA ​solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable."
"The technical support could be better. Whenever I contacted support, I rarely got the solution that we needed. And most of the time, I finished fixing the problem by looking on the internet or by finding documents about the problem on Google."
"We would like to see some fairly large scale improvement in the configuration process for this solution."
"I would like to see the virtual and desktop license included in the pricing."
"Security could be improved because then I can get rid of my Cisco firewalls. If they improve the security then I could run my security, my proxy, my firewalling and my SDN solution on one device instead of having to have multiple devices."
"The setup for Citrix NetScaler has room for improvement. It could be easier."
"We face challenges with the solution's firmware upgrades frequently."
"Reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement."
"The technical support could be improved. They do not respond or assist customers in a timely manner."
 

Pricing and Cost Advice

"It is free of cost."
"The licensing fee for the solution is $690 per unit annually."
"The tool is open-source."
"HAProxy is free in the initial offer. However, pricing can be improved."
"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"The product is open source."
"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"Citrix NetScaler VPX is not the cheapest solution out there, but you get what you pay for."
"Price-wise, I feel that the solution is a little bit expensive."
"We have all the features and functions of Citrix because we have a premium license."
"We are quite happy with price. It's not too high."
"It all depends on the features that will be used and the number of accesses."
"It's not for startups or SOHO."
"It is an enterprise solution. Thus, its costs are reasonable."
"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
