HAProxy Pros review quotes

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.

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.

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 features I find valuable in this solution are session control which automatically disconnects users that forget to log off, and the ability to write rules to either allow or block certain file requests.

It is a crucial tool in ensuring smooth service provision without any interruptions.

Stability is number one.

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.

Load balancing is valuable, and we are also using the WAF feature.

Sometimes it's challenging to get through the log, and you need a log to understand what is going on. It isn't easy to map the logging with the documentation, and every time I read the log, I have to pull out the documentation to understand what I'm reading.

The only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration. A GUI/web interface could be helpful for users who are not as experienced in the Linux shell. However, HAProxy does have another product that we evaluated called ALOHA, which has a web front-end, but we found it did not meet our needs.

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.

HAProxy is very weak in the logging and monitoring part and requires improvement.

The GUI should be more responsive and show the detailed output of logs.

The solution can be improved by controlling TCP behavior better and mandating to clients what the expected outcome must be in order to avoid receiving contestant timeout logs.

There is room for improvement in HAProxy's dynamic configuration.

The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added.

The web stats UI, which provides the status of the health and numbers, could greatly benefit from having a RESTful interface to control the load-balanced nodes. Although there is a hack around the UI (by issuing a POST request to HAProxy with parameters), a RESTful interface would greatly improve the automation process (through Chef and Ansible).

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.
