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

"It’s a reliable product with good technical support."
"​It has allowed us to evenly distribute the load across a number of servers, and check their health and automatically react to errors."
"We use it as a load balancer for our application servers."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"I can't speak to all of the HAProxy features because we don't use them all, but load balancing is very good."
"HAProxy's TCP load balancer is excellent and super stable."
"The solution is effective in managing our traffic."
"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."
"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."
"It seems to provide a bit of useful information on website health."
 

Cons

"The basic clustering is not usable in our very specific setup."
"The logging functionality could use improvement, as it is a little cryptic."
"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."
"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."
"Documentation could be improved."
"While the product is quite perfect, it could use more supervision and be more active. Also, more simplicity, more peripherals, and more scalability."
"Maybe HAProxy could be more modular."
"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."
"Sitelock may perform a useful service, but be wary of giving them your credit card information."
 

Pricing and Cost Advice

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"The tool is open-source."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
"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."
"HAProxy is a free open-source solution."
"It is free of cost."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"You can't just stop auto-renew from your billing panel, the way you can with reputable businesses."
