It requires high CPU utilization.

Availability of integration via APIs.

Issues in SSL certificate management.

System configurations and settings decisions for load balancing. Review collected by and hosted on G2.com.

"A trusty tool"

4.5/5

What do you like best about HAProxy?

HA Proxy is simple to use and reliable. It does one basic thing, and it does it well. The interface is clean and easy to use, the web monitoring is fine, easy to hook up - and can be used for a variety of services - not just for HTTP/HTTPS only. The best thing about it is the ease of use - one config file, and everything is easy to configure - or automate. Also, there are many plugins for automation tools, so you can plug it into ansible, puppet, or whatever you use. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

There is very little to dislike about it - maybe it's the speed of adopting new things, but that's about it. Review collected by and hosted on G2.com.

Recommendations to others considering HAProxy:

As far as generic proxy solutions go, this is probably the best in the F/OSS space. It's very stable, robust, and supports a lot. There are specialized tools that can be better for specialized cases, but for a generic HA proxy (as the name implies) this is a very good solution. Also, when there is no specialized tool - this one will work in almost any case. Review collected by and hosted on G2.com.

What problems is HAProxy solving and how is that benefiting you?

I've used it to solve not only reverse proxy/load balancing of HTTP servers but also various other services - database, search.... a lot. It solved issues regarding both availability and load balancing. Review collected by and hosted on G2.com.

"Experience with HAProxy in development, test & production environment"

5/5

What do you like best about HAProxy?

Although the primary purpose of the software is to be load balancer, I'm using it as proxy because Kubernetes & Docker do other stuff. Amazing things can be achieved with HAProxy when it comes to Redirection and Routing, every possible detail imaginable. When it comes to connecting Microservices, it ends the right thing. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Everything is amazing. It is very easy to learn Review collected by and hosted on G2.com.

"Good replacement for hardware based load balancer"

4.5/5

What do you like best about HAProxy?

The enterprise edition provides good redundancy. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Active-active supports requires network-specific support. Review collected by and hosted on G2.com.

Response from Jakub Suchy of HAProxy

edit

Many thanks for your review! It's true, active-active support requires Route Health Injection through BGP or other protocols. Unfortunately, there are not that many ways around that...

"HAProxy was here in the beginning and will be here in the end."

4/5

What do you like best about HAProxy?

HAProxy is fast. It doesn't aspire to do more than that. It's a fast TCP proxy with Layer 4 and Layer 7 functionality that makes it useful in a range of environments where you want functionality without bloat. Focus without compromise. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

Because it's specialized, it's entirely possible to overlook what it's good at. Other solutions offer a toolbox of features, but by doing so, are they excellent at any one of them? My experience with HAProxy has always been that I could rely on it to do what it needed to do, where I needed it done, and I knew that once deployed, it would work tirelessly. I've never had HAProxy fail in the 10+ years I've been using it. Review collected by and hosted on G2.com.

What problems is HAProxy solving and how is that benefiting you?

I use HAProxy in front of Kubernetes clusters, either to load balance traffic to the ingress controller running on multiple nodes, or to load balance the Kubernetes API for HA clusters. I also punch TCP ports through it, do SSL termination on it, and use it for elaborate URL and header rewrites for applications that have been wedged into multiple containers but weren't designed to be carved up like that. Having a load balancer present in my environment makes it easy to use it as the frontend for all sorts of applications, giving them stable, friendly DNS names and running them as HTTPS apps instead of bizarre HTTP apps on port 3000 or 8080 or other random ports.

"The piece of software that really works for what you are looking forward and really easy to learn."

5/5

What do you like best about HAProxy?

The simple way to install and configure. The minimum resources it requires and the availability to distribute the application per paths from different VMs/appliances. Also the easy way to set up HA.

The simplicity that you set your rules is really intuitive and the documentation is really clear.

Having also the possibility to change the configuration on-the-fly using an API is also a MUST.

Also the support is something that is always available and sometimes even go further the scope to provide an excellent experience. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

There's not much I would point I would dislike. More likely would point some extra features would be a plus to have.

For example, would a GUI for configuration would be a plus. Although not mandatory for me, as I do prefer to work with config files, sometimes for some co-workers it would help to have it done easier. Review collected by and hosted on G2.com.

Recommendations to others considering HAProxy:

There are other options on the market, but I would prefer stability, and and excellent support rather that try outs.

HAProxy has proven over the times it's ready to handle any kind of workload and you can load between TCP or HTTP, in any port or service.

Their added modules are a plus, like bot protection, WAF and HA builtin features. Review collected by and hosted on G2.com.

What problems is HAProxy solving and how is that benefiting you?

Using some caching servers as Varnish, whom do not provide SSL termination, HaProxy was a natural option and the entry way for that.

As long as the application increased complexity and we would need to have HA from different services replicas, it has become more used. Furthermore, balancing between datasets was also a plus. Review collected by and hosted on G2.com.

"HAproxy best thing to distribute the traffic"

5/5

What do you like best about HAProxy?

I have used the Round Robin method with 3 and 5 different servers having same code files and thats worked for me. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

May be nothing. This is the best one to distribute your website traffic. Review collected by and hosted on G2.com.

"Powerful load balancer"

4.5/5

What do you like best about HAProxy?

Very fast and reliable load balancer with many features Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

It has quite a complicated config file, some issues with CPU utilization. Review collected by and hosted on G2.com.

Response from Jakub Suchy of HAProxy

Many thanks for your review! CPU usage grows with Load Balancing when you are doing TLS termination. I recommend always using EC certificates, as they are much more performant than RSA ones.

"HAProxy as a loadbalancer in production"

5/5

What do you like best about HAProxy?

HAProxy can be setup within minutes and can start working. ACLS are the most favorite part that I like , we can distribute our traffic on different domains using ACL. Also the ability of dynamically applying the right SSL certificate for a domain in case of multiple domains with SSL is the best. Review collected by and hosted on G2.com.

What do you dislike about HAProxy?

It should provide some hint or example files configuration for quick setup. Review collected by and hosted on G2.com.
