What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks. The reliability features of HAProxy were particularly useful in a scenario where I needed to test load balancing between two Tomcats. Since these domains were inaccessible, I set up a third Docker with HAProxy, which had access to the Tomcat domains. I then configured HAProxy to handle the load balancing. This setup allowed the client to interact with HAProxy. The solution's integration with other elements is easy.

If a Linux user who is fairly good with Linux products takes care of HAProxy's installation part, it can be done easily. It is possible to deploy the product within one to three hours with a fair amount of knowledge. The product's deployment process is straightforward, as it can be easily managed with the help of HAProxy's document, which is available on its website. Users should be familiar with some Linux commands. The solution is deployed on the cloud and on-premises models. HAProxy is similar to engine NGINX, especially if you have a small company since you need only one or two people to take care of the deployment process. If you have a big enterprise, five to ten people are required to take care of the deployment phase.

Valuable Features

Users find HAProxy valuable for application load balancing, TCP/IP Layer 4 functionality, protocol-level decisions, ease of deployment and scalability, open-source benefits, customization, stability, user-friendly interface, simplicity, and cost savings.

"We use the solution for load balancing."

"The solution is effective in managing our traffic."

Room for Improvement

HAProxy needs better documentation, improved pricing, and enhanced monitoring and reporting. Users find customization and troubleshooting challenging and seek more programming integration. The dashboards and user interface require improvements for better visibility and functionality. Logging and dynamic configuration changes can be tough to manage and require enhancements for clarity. Stability issues arise under heavy traffic, and better security models are needed. Integrations and support for multiple languages are also areas requiring attention.

"The solution's dashboards and reports could be improved."
"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."
"The product does not have any new technologies."

ROI

The ROI from HAProxy is rated four out of five. It offers a good return by replacing OEM solutions with an open-source option, saving on traditional load balancer costs. It aids in customer retention and is preferred for managing traffic without high-end expenses.

Pricing

HAProxy is predominantly free, as it is open-source software. Many users leverage the freeware version, finding it fits well within their tech stack. The setup is straightforward, typically taking a day for completion. Some respondents mentioned inexpensive licensing models but did not provide specific costs. Overall, enterprises appreciate the cost-effectiveness and flexibility offered by HAProxy due to its open-source nature.

Popular Use Cases

The primary use case of HAProxy is for load balancing across various applications and environments, including production, UAT, and financial trading systems. It is also employed for managing Redis clusters, controlling IP addresses, blocking invalid requests, SSL termination, and handling high-traffic API gateways. HAProxy is used as a reverse proxy for different environments, balancing HTTP and TCP traffic, and forwarding traffic for SMTP, SMPP, and email services.

Service and Support

Customers find that HAProxy's customer service and support are mostly reliant on self-service and community resources due to its open-source nature. Some users opt for premium support, which is responsive but could benefit from improved documentation. Several customers express a preference for self-research through available online resources. Support is described as good but impacted by communication delays and global shift changes. Many would appreciate better online documentation and knowledge bases.

Deployment

HAProxy's initial setup is generally straightforward and easy, especially for those with container and VMware knowledge. Documentation is useful but may require customization. Most setups are quick, ranging from minutes to a few days. Some find it as simple as other load balancers, while others consider it challenging and comparable to F5. Users with Linux expertise can deploy HAProxy swiftly, but larger enterprises might need more personnel for deployment. Automation tools like Terraform can expedite the process.

Scalability

HAProxy is considered highly scalable, supporting various user loads effectively. Users have reported it can efficiently handle thousands of connections daily. Many find it suitable for small to large enterprises, with some scaling up using multiple servers. Performance depends on the underlying hardware, but no significant issues with load handling have been mentioned. Users rate its scalability features positively, highlighting its adaptability and ease of scaling both the application and backend environments.

Stability

HAProxy is frequently updated as it is open-source. Users describe it as rock solid, generally stable, and reliable. Stability issues are rare, often linked to configuration or compatibility with other products. HAProxy efficiently handles failures, maintaining stability even if nodes go down. Users rate its stability highly, often eight or nine out of ten. It passes stability tests and is deemed very stable by infrastructure teams. Stability improvements are occasionally suggested.

Reviews from Real Users

“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.

HAProxy was previously known as HAProxy Community Edition, HAProxy Enterprise Edition, HAPEE.
