Cluster Solution Prevents Interruption of Service Caused By Inundation
What is most valuable?
How has it helped my organization?
Four days ago, I had an inundation in my informatic room, and there was no interruption of service, because HAProxy is an excellent cluster solution.
What needs improvement?
While the product is quite perfect, it could use more supervision and be more active. Also, more simplicity, more peripherals, and more scalability.
For how long have I used the solution?
About five years.

What do I think about the stability of the solution?
Yes, the first time. I have an old VMware vCenter Server 6.0 . The VMware vCenter Server 6.0 cannot go with HAProxy. HAProxy developed a special feature for me to improve the function.
What do I think about the scalability of the solution?
No issues. I have about 500 users on HAProxy, which use a web server and mail server.
How are customer service and support?
No majors issues to contact them, but did contact them regarding questions about the product.
Which solution did I use previously and why did I switch?
I have used before a server from Microsoft, and a server is very slow as a solution.
How was the initial setup?
The product is very simple to install and to use.
Which other solutions did I evaluate?
Yeah, but I don't remember it, because the other product was very bad in comparison to HAProxy.
What other advice do I have?
The product is very simple and fast. It's a microchannel.
Try it and if you like it, you buy it.

We have been able to achieve high performance load balancing in a short amount of time
What is most valuable?
The heavily tuned full stack (NIC, kernel, and user space) produces excellent performance. Their support is available for advanced troubleshooting.
How has it helped my organization?
We have been able to achieve extremely high performance load balancing in a short amount of time. As an example, using L4 mode, we routinely return more than 100 gigabytes per second of MySQL traffic, from a cluster of about 10 replicas.
What needs improvement?
The GUI is clunky and the on-board metric viewing solution is poor. We ship metrics off the appliance to InfluxDB (using CollectIT, which is bundled with the appliance), to view them directly with Grafana.
For how long have I used the solution?
We have used this solution for around five years.
What do I think about the stability of the solution?
During our seven years with these appliances, we have found some problems, typically under very extreme conditions. In each case, the issue was quickly escalated to a team led by the CTO at Aloha.
During one of these cases, they found three separate OpenSSL bugs, and one of them was not previously reported. We also moved to using Intel NICs. Our initial batch of appliances had a different manufacturer, which struggled when pushed to the line rate.
What do I think about the scalability of the solution?
Full layer 7 SSL termination is limited to a single core, which is a problem. We have worked around it terminating SSL on the back-ends, but this is not ideal.
How are customer service and technical support?
Technical support is truly exceptional. The initial layer is highly technical, and can reproduce problems and provide details. Serious issues are quickly escalated to the senior R&D team.
Which solution did I use previously and why did I switch?
We have moved all of our basic load balancing onto these devices. We previously used Citrix NetScalers, which were expensive, harder to configure, and more challenging to troubleshoot.
How was the initial setup?
The initial setup was trivial.
What's my experience with pricing, setup cost, and licensing?
Compared to the others in the market, such as Citrix and F5, the cost per performance for Aloha appliances is extremely low. In our experience, the performance and reliability is better.
Which other solutions did I evaluate?
We strongly prefer to go with Open Source solutions. We evaluated https://www.loadbalancer.org/ as well. We went with Aloha because of the in-house expertise that Aloha has. The primary developer of HAProxy works there.
What other advice do I have?
Go for it. These systems are exceptional.

Reliability and transparency are the most valuable features
What is most valuable?
Reliability and transparency are the most valuable features.
How has it helped my organization?
This product is replacing another balancer which was not supported anymore. So, there is no major improvement for us.
In general, the improvement is in terms of the balancer sense which is moving from a single web server/single point of failure to using several back-end servers, that greatly improves the speed and reliable uptime.
What needs improvement?
I would improve the web-based UI, but it’s a matter of personal preference.
For how long have I used the solution?
I have used this solution for one year.

Which solution did I use previously and why did I switch?
Previously, we were using another product but it is no longer supported.
How was the initial setup?
For the most part, the setup is pretty straightforward. However, as I mentioned earlier, thanks to the very good and quick technical support, all the complex requirements that we had were resolved quickly.
What's my experience with pricing, setup cost, and licensing?
The pricing is good compared to the other similar products.
Which other solutions did I evaluate?
We evaluated at least four to five other products.
What other advice do I have?
It’s a reliable product with good technical support.

Others should try it out, for sure. It’s a great solution backed by a very smart set of technical folks.
What is most valuable?

Which solution did I use previously and why did I switch?
Yes, Citrix Netscaler. We switched for the reasons above.
How was the initial setup?
Complex, but their technical staff has made excellent progress on our migration to date.
Which other solutions did I evaluate?
Other popular Load Balancer solutions out there

Helps distribute the server load but has only the basic features
Pros and Cons
- "The solution is effective in managing our traffic."
- "The product does not have any new technologies."
What is our primary use case?
The solution is used for high availability. We use it for the backend to distribute the load.

The tool is scalable. We have everything we need.
What's my experience with pricing, setup cost, and licensing?
The product is open source.
What other advice do I have?
There are better tools, but the product does the job well. All my colleagues know the tool and have used it. I recommend the product to others. Companies that have complex environments must not choose HAProxy. Overall, I rate the solution a seven out of ten.
