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.

It's not easy to get out once you're in
Sitelock may perform a useful service, but be wary of giving them your credit card information. When you sign on for the paid service, Sitelock: * Hides (makes it difficult to find) that they default the auto-renew (you can't sign up without agreeing to have them automatically bill your credit card every year). * Hides (makes it difficult to find) how to stop auto-renew: * You can't just stop auto-renew from your billing panel, the way you can with reputable businesses. * You have to hunt their website for a link (in extremely small font) to the page which contains instructions for cancelling. * When you get to that page, turns out it's the 5000+ word "Terms of Service" document, which you have to scour to find a phone number. Then, you have to call and get put on hold (or if you like, they will call you back three days later). Once you finally get through, you have to jump through a lot of security hoops. All of the above, just to cancel the service. Their product may or may not be OK, but be forewarned that with Sitelock, it's not easy to get out once you're in.

Quotes from Members

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

Pros

"The solution is user-friendly, works quickly and efficiently."
"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 use the solution for load balancing."
"We never have any downtime with it."
"Software defined load balancing allows us to dynamically adjust and codify routing decisions, which speeds up development."
"​​Reliability. HAProxy is the most reliable product I have ever used."
"The anti-DDOS PacketShield filtering solution (embedded in the physical appliances) as well as the BGP route injection are great features and heavily used."
"The stability is good and passed all tests."
"It seems to provide a bit of useful information on website health."
"Not only did SiteLock's website scanner find the issue with my website, but with SiteLock I was able to implement a security system to prevent future breaches."
 

Cons

"A significant area for improvement in HAProxy is its tenancy model; managing multiple environments can be challenging, especially with mergers, acquisitions, or domain changes."
"An alerting system would be better as I need to check log files if any backend is down."
"I would like to evaluate load-balancing algorithms other than round robin and SSL offloading."
"The basic clustering is not usable in our very specific setup. The clustering is mainly a configuration replication and is great in a case of active-passive usage. In the case of an active-active (or with more than two nodes) where the configuration is not fully identical, it cannot be used as-is."
"The only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration."
"Maybe HAProxy could be more modular."
"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 deployment and configuration of HAProxy are not easy if we compare it with other solutions, such as F5."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"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."
"We are using HAProxy as an open-source."
"HAProxy is a free open-source solution."
"The product is open source."
"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."
"The tool is open-source."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
