Find out what your peers are saying about F5, HAProxy, NetScaler and others in Application Delivery Controllers (ADC).
The major return on investment is the security of our data.
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.
I would rate the technical support of F5 BIG-IP Local Traffic Manager (LTM) nine out of ten.
Overall, my experience with F5 is very good compared to Radware.
Customer support is quite good but could be faster.
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.
Response time is good because they have assigned and dedicated support engineers to us, and we have weekly cadence calls.
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.
While some people use NGINX for web servers, my current use case focuses on networking and tunneling, which does not necessitate much scaling.
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.
I require ninety-nine point nine percent uptime, and NGINX has been pivotal in helping me achieve this along with our other DNS services.
I expect faster resolutions when providing contact numbers while raising cases, as other companies typically do.
The pricing of F5 BIG-IP Local Traffic Manager (LTM) is on the higher side compared to competitors, but it is worth it.
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.
NGINX could provide a means to generate self-signed SSL certificates.
As with any application, there were initial issues, however, after receiving support, everything was rectified.
There were some vulnerabilities in F5.
The product is costly.
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.
My use case involves using the free and open-source version of NGINX, making it cost-effective as I haven't incurred any costs.
The solution offers a cost advantage.
The impact of SSL offloading on reducing server load and latency is very much positive because whatever traffic we receive, we encrypt at our F5 BIG-IP Local Traffic Manager (LTM) level, which has definitely reduced the additional load and SSL decryption load on the servers, so it has very much helped us and it is very smooth; it will not take much time and will not impact our regular traffic.
R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.
One of the most beneficial features of F5 BIG-IP Local Traffic Manager (LTM) is its ability to identify compromised traffic and its capabilities in authentication.
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.
For API management, the WebSocket, and the WebServer, NGINX provides a cost advantage, value addition, and effective support.
The web application firewall feature has helped enhance security for our applications because most of the attacks which are performed on our website are being blocked by it.
