Setup Cost

F5 BIG-IP LTM is feature-rich but costly, especially in AWS; consult F5 for tailored licensing options.
Enterprise users value HAProxy's competitive pricing and cost-effective licensing, especially compared to F5 and Citrix, despite initial setup costs.
NGINX Plus has a modular licensing model with varying costs, offering value but can be expensive compared to alternatives.
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
Setting up HAProxy didn't cost anything for me.
DevOps engineer at a tech services company with 1-10 employees
The pricing remains competitive compared to other vendors.

Valuable Features

F5 BIG-IP LTM excels in load balancing, security, and customization, enhancing performance and reliability for complex network environments.
Users praise HAProxy for reliable load balancing, customization, low latency, open-source benefits, and advanced features like secure traffic management.
NGINX Plus excels in load balancing, security, and integration, praised for simplicity, efficiency, and superior traffic management features.
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.
Project Manager at IBM
R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.
Network Engineer at Stryker
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.
IT Manager at Chong Hua Hospital
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
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.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
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.
CEo at CloudPositive
For API management, the WebSocket, and the WebServer, NGINX provides a cost advantage, value addition, and effective support.
Executive Director at Geojit
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.

Load balancing has improved traffic distribution and currently supports high availability upgrades
F5 BIG-IP Local Traffic Manager (LTM) offers effective load balancing methods that help distribute traffic across our servers, whether we have two or several. This load balancing feature stands out as it is the fundamental work we do with F5 BIG-IP Local Traffic Manager (LTM). While I recognize there are many features, such as iRules, which I have not explored yet, we primarily work on VIPs, pool members, and traffic distribution. The load balancing algorithms' flexibility makes them very useful for our team, enabling us to choose different servers and manage load effectively. We use various methods based on user or application requirements, making the algorithms set up by F5 in the backend quite helpful. F5 BIG-IP Local Traffic Manager (LTM) positively impacts our organization primarily through its load balancing capabilities. We avoid traffic overload on individual servers by placing backend servers behind F5 BIG-IP Local Traffic Manager (LTM) VIP. This load balancing helps us manage traffic effectively. Since the configuration of the I-series, we have had smooth performance, and with the recent migration to the R-series, it is working faster than before, providing positive outcomes for our operations. Since moving to the R-series, I notice improved performance; it is user-friendly and handles traffic efficiently. The upgrading process is different as we create tenants and a main host. R-series has better CPU and memory, leading to higher throughput with minimal downtime, making it a significant improvement over the I-series.

Handles high traffic efficiently and simplifies complex routing with rule-based logic
I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.

Advanced policies and web firewall have strengthened application protection and reduced attack traffic
There were some vulnerabilities in F5. They tried to fix it, but the fixes were not available at the time because they were zero days, so they attempted to fix it, but their support was not proper. Their support should be improved because sometimes features which we need for customization take time, and they are sometimes feasible and sometimes not feasible by the team, so their support and the engineering team should improve their product. I would like to see more features regarding customization which should be built into the application, and the tool optimization should be good, and the dashboard should be more crisp and clear.
