Comparison Buyer's Guide

Executive Summary

Review summaries and opinions

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

ROI

Sentiment score
7.2
F5 BIG-IP AFM offers ROI and cost efficiency when integrated, but standalone ROI is below average, despite perceived value.
Sentiment score
7.1
HAProxy's open-source load balancer cuts costs, boosts efficiency, improves uptime, reduces staffing, and enhances scalability for users.
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.
Junior System Administrator & DevOps at a tech services company with 11-50 employees
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.

Customer Service

Sentiment score
6.5
F5 BIG-IP AFM support is praised for professionalism but needs faster ticket resolution and improved recommendation accuracy.
Sentiment score
6.5
HAProxy's customer service and technical support are highly rated for quick, expert assistance, though documentation could improve.

7.9
HAProxy efficiently handles scalability, easily adapting configurations for growing traffic, ideal for small to medium businesses and larger environments.
The solution is highly scalable, allowing me to add or remove nodes and manage traffic without interruption, which is essential for meeting application demands.
System Advisor at CRIF SpA
We manage an automatic load balancing feature where we add HAProxy servers dynamically behind the application load balancer to handle more traffic.
Head of DevOps at TripFactory
HAProxy's scalability is excellent; as our traffic expands, it handles load increases effortlessly.

Stability Issues

Sentiment score
8.4
F5 BIG-IP AFM is lauded for its stability and reliability, with high user ratings and minimal operational issues.
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 AFM is costly, complex, needs dashboard improvements, enhanced features, better integration, and concerns over CPU and support.
HAProxy needs a revamped GUI, improved APIs, better AWS integration, real-time config, enhanced docs, and stronger monitoring and security.
Having advanced technology similar to other vendors like Palo Alto for zero-day attack prevention would be valuable.
Network Security Engineer at IIPL
The appliance and features could be enhanced further, especially in terms of security.
System Advisor at CRIF SpA
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 AFM is costly but justified by its features, with pricing for licenses and potential extra feature fees.
Enterprise users value HAProxy's competitive pricing and cost-effective licensing, especially compared to F5 and Citrix, despite initial setup costs.
The standard license is reasonably priced, but additional features like the WAF can be more expensive.
System Advisor at CRIF SpA
If considering a one-stop solution that provides load balancing, DNS security, AAA authentication, and firewalling on the same hardware, the cost is reasonable.
Network Security Engineer at IIPL
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 AFM offers robust network security, ease of use, and supports cloud migration with AI-driven features.
Users praise HAProxy for reliable load balancing, customization, low latency, open-source benefits, and advanced features like secure traffic management.
The solution provides behavioral analysis via AI to detect malicious traffic.
Network Security Engineer at IIPL
The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications.
System Advisor at CRIF SpA
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.

Provides outstanding resource management and application security across multiple geographies
The most valuable features for me are stability, availability, and security, along with the ability to manage multiple features to secure my applications. The solution also monitors and blocks unconventional requests and maintains security efficiently. The scalability feature also allows me to manage and allocate resources dynamically without disrupting production traffic.
Shrinivas Devarkonda - PeerSpot reviewer
Head of DevOps at TripFactory
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.
