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 VRRP redundancy is also a mission-critical feature that works seamlessly. I can bring down a server live with minimal downtime because of this."
"The feature that I have found the most valuable is that it works for my use case of application load balancing. I'm using it for PeerSense, and it's easy enough for PeerSense."
"It is stable. Period. Will not fail unless you do something wrong."
"I estimate that this product has saved our company hundreds, if not thousands, of dollars in possible downtime from previous load balancers. We make a lot of our money from online sales, so it is critical to have 99.9% uptime."
"We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host."
"Stability is number one."
"The most valuable thing for me is TCP/IP Layer 4 stuff you can do with HAProxy. You can go down to the protocol level and make decisions on something."
"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."
"Easy, user-friendly setup with content switching and integrated caching features."
"The load balancing is one of the most valuable features."
"The GSLB feature allows us to move services between data centers. We can do this in either a planned or unplanned manner. We have experienced service provider outages at our primary data center and GSLB will kick in to automatically modify DNS records to point to a secondary data center (active/passive). We also make use of GeoIP information to point clients to the closest data center for accessing applications."
"For desktop application management, I recommend the NetScaler edition. This product is like a Swiss army knife. Citrix NetScaler ADC supports the education front-end."
"Content filtering, security layer, and application customization features are the most valuable."
"We have good customer support."
"The most valuable feature is load balancing."
"Its flexibility, agility, and robustness are the most valuable. Its management and implementation are also quite easy."
 

Cons

"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."
"They should introduce one feature that I know many people, including me, are waiting for: HAProxy should have provide hot-swipe for back-end servers. Also, they need a more detailed GUI for monitoring and configuration."
"The configuration should be more friendly, perhaps with a Web interface. For example, I work with the ClusterControl product for Severalnines, and we have a Web interface to deploy the HAProxy load-balancer."
"The GUI should be more responsive and show the detailed output of logs."
"If nbproc = 2, you will have two processes of HAProxy running. However, the stats of HAProxy will not be aggregated, meaning you don't really know the collective status in a single point of view."
"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."
"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."
"I would like to evaluate load-balancing algorithms other than round robin and SSL offloading. Also, it would be helpful if I could logically divide the HAProxy load-balancing into multiple entities so that I would install one HA Proxy LB application which could be used for different Web servers for different applications. I am not sure if these features are available."
"They can improve the scalability and the multi-tenancy feature. We recently tried to configure an authentication, and we ran into some issues while using the web-based GUI. It was very slow when you log in with your credentials in the web-based GUI. Each time we clicked on the menu, it tried to do the authentication. It works properly in the console."
"Deployment is complicated."
"We face challenges with the solution's firmware upgrades frequently."
"The GUI should be improved."
"I would like to see multifactor authentication added to this solution to improve the security."
"Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us."
"ADC from Citrix has added functionalities from other products and the usability is very difficult for someone who is used to a simpler user interface, it's a little bit of a mess to use."
"Citrix Web App and API Protection could improve in the area of licensing"
 

Pricing and Cost Advice

"We are using HAProxy as an open-source."
"The tool is open-source."
"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 licensing fee for the solution is $690 per unit annually."
"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​."
"HAProxy is an open-source solution."
"The firewall license is included by default, with no additional costs."
"Its price is comparable to others and affordable."
"This product is more expensive than some of the competitors."
"It is very pricey, but we get it. If you need the best, money shouldn't be a problem."
"It's an expensive product but it works well."
"We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them."
"Citrix NetScaler VPX is not the cheapest solution out there, but you get what you pay for."
"Ninety day free trial makes it easy to try out this solution."
