Find out what your peers are saying about F5, NetScaler, HAProxy and others in Application Delivery Controllers (ADC).
Operational efficiency has improved; we no longer have staff consistently monitoring backend servers during deployment or scaling events, as HAProxy's health checks and hitless reloads allow us to push changes with minimal manual intervention.
This resulted in a drastic decrease in costs and, at the same time, the accuracy of the hits coming on HAProxy was almost around 100% or 99.99%.
I estimate seeing a return on investment with HAProxy, as it significantly reduced staff requirements and enhanced scaling capabilities, particularly when transitioning from NGINX, which faced issues.
Since we are utilizing the open-source edition, community forums, mailing lists, and GitHub have been invaluable, with typically someone having encountered the same problems we faced.
My interactions with HAProxy's customer support were limited, but the feedback from my team indicated satisfactory service.
We have not received technical support from Kemp LoadMaster without a license.
We manage an automatic load balancing feature where we add HAProxy servers dynamically behind the application load balancer to handle more traffic.
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.
For scalability, HAProxy meets my needs, supporting our initial horizontal scaling and then adapting to vertical scaling in a VMware environment.
Kemp LoadMaster is a scalable solution.
This reliability serves as a key reason for our choice, providing us with confidence even when faced with heavy traffic.
The hot reload feature of HAProxy also really helped us so that we never had to shut it down to reload it.
We have reduced a lot of servers, replacing them with one or two HAProxy servers which deliver better performance, accuracy, and an almost 100% success rate with requests.
With the license purchase afterwards, if it expires, it begins dropping the HTTP traffic, also the DNS traffic.
The configuration syntax is powerful yet can become overwhelming for newcomers; a more beginner-friendly interface or a native GUI without relying on third-party tools would ease the onboarding process.
An easier desktop interface to connect to a remote server and make changes on my PC would be beneficial.
The reloading functionality is effective as it allows soft reloads without interrupting traffic patterns.
After that, they said if it was good, we could purchase the license, and while we found it very good, the license cost was too high.
Since we use the open-source edition, there are no licensing fees, with the main cost being the infrastructure running on EC2 instances in AWS, which helps maintain low expenses.
Setting up HAProxy didn't cost anything for me.
The pricing remains competitive compared to other vendors.
By moving all SSL termination to the load balancer, I now manage certificates in a single place, and I can also utilize Let's Encrypt with HAProxy's built-in ACME support, making renewal automatic.
HAProxy positively impacted our organization by exceeding scalability expectations, initially projected at 200k requests but ultimately handling over 15 million transactions per second without any issues.
As a production engineer at that time, I definitely wanted to ensure that the system could handle massive connections, especially since we operated an e-commerce platform where we could not lose any customer calls.
We had some issues in patching management, so we deployed this product for virtual patching, the IPS rule, and it gives us very good results because we have very critical servers.
