ROI

Sentiment score
6.6
Many companies found F5 BIG-IP LTM beneficial for security and deployment, with mixed views on ROI depending on pricing.
Sentiment score
7.1
HAProxy's open-source load balancer cuts costs, boosts efficiency, improves uptime, reduces staffing, and enhances scalability for users.
The major return on investment is the security of our data.

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%.
Head of DevOps at TripFactory
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.

Stability Issues

Sentiment score
8.0
F5 BIG-IP LTM is stable and reliable, with occasional bugs manageable through updates, supported by responsive customer service.
Sentiment score
8.1
HAProxy is reliable, handles heavy traffic efficiently, with minimal downtime, quick support, and frequent updates enhancing stability and performance.
This reliability serves as a key reason for our choice, providing us with confidence even when faced with heavy traffic.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
The hot reload feature of HAProxy also really helped us so that we never had to shut it down to reload it.
CEo at CloudPositive
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.
Head of DevOps at TripFactory
 

Room For Improvement

F5 BIG-IP LTM needs better cost-effectiveness, user interface, cloud integration, documentation, security, automation, and a flexible licensing model.
HAProxy needs a revamped GUI, improved APIs, better AWS integration, real-time config, enhanced docs, and stronger monitoring and security.
I expect faster resolutions when providing contact numbers while raising cases, as other companies typically do.
Network Engineer at Stryker
The pricing of F5 BIG-IP Local Traffic Manager (LTM) is on the higher side compared to competitors, but it is worth it.
Project Manager at IBM
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
An easier desktop interface to connect to a remote server and make changes on my PC would be beneficial.
DevOps engineer at a tech services company with 1-10 employees
The reloading functionality is effective as it allows soft reloads without interrupting traffic patterns.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

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.
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.
Principal Engineer Manager at a manufacturing company with 501-1,000 employees
 

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.
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.

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.
