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.

The best features that Ivanti Virtual Application Delivery Controller (vADC) offers include its ability to help make us compliant at 95%, which is a big win if you are able to comply with 95% of devices, and it is also helpful for providing exact error codes, allowing us to troubleshoot accordingly. The features of Ivanti Virtual Application Delivery Controller (vADC) impact my daily workflow by saving time and helping in troubleshooting as well. Ivanti Virtual Application Delivery Controller (vADC) is very helpful, and I have nothing else to add about its features. Ivanti Virtual Application Delivery Controller (vADC) has positively impacted my organization by allowing us to comply with all the servers with security patches, which include many bug fixes and do so in no time. With Ivanti Virtual Application Delivery Controller (vADC), we are able to patch servers faster than we used to do via SCCM, and we save at least two to three hours in our global patching.

Quotes from Members

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

Pros

"Since the deployment is very easy and the open-source functionality saves a huge amount of cost in terms of project deployment."
"The technical support has been, in one word, perfect. Every time I call, I’m on the phone with a representative within five minutes who is highly skilled and willing to help, whether in the case of critical issues or simple advice."
"HAProxy's TCP load balancer is excellent and super stable."
"HAProxy is highly customizable and will meet the business demands of most companies."
"​​Reliability. HAProxy is the most reliable product I have ever used."
"The most important features would be the load-balancing of HTTP and TCP requests, according to multiple LB-algorithms (busyness, weighted-busyness, round robin, traffic, etc). Another important feature that we cannot live without is the username/passwd authentication for legacy systems that had none."
"We never have any downtime with it."
"I have found HAProxy very helpful in replicating production environment architecture in a development and testing environment."
"Ivanti Virtual Application Delivery Controller (vADC) is a very good tool that companies should use, as it is very reliable, very fast, and allows you more time to work on other cases because Ivanti handles everything smoothly."
 

Cons

"The product should have more security and dashboard functionality for monitoring so that any administrator can see the usability and track all the incoming and outgoing requests."
"While troubleshooting, we are having some difficulties."
"I would like to see a two (or more) native cluster support without third parties or DNS manipulations."
"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."
"HAProxy is definitely a power-user tool. It is enormously scalable and flexible, but this can come at the cost of usability."
"A better GUI would be nice."
"Maybe HAProxy could be more modular."
"The tech support is good however, there are sometimes delays in resolving issues because when there is a shift change there doesn't seem to be any communication between the support staff and we are constantly having to repeat our issues to the next person."
"To improve Ivanti Virtual Application Delivery Controller (vADC), I would suggest integrating something to fix the registry of a server, as including any steps that fix the registry or any DLL files causing issues where patches did not install properly would be beneficial."
 

Pricing and Cost Advice

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"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."
"HAProxy is free open-source software."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"HAProxy is a free open-source solution."
"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."
"HAProxy is free in the initial offer. However, pricing can be improved."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
