Find out in this report how the two Web Application Firewall (WAF) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI.
Realizing a 30 to 50% reduction in latency and page load time, ensuring users experience a seamless workflow.
I have seen a return on investment, particularly in time savings, especially regarding the changes.
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.
demonstrating the team's technical expertise in CDN and Edge architecture
We have SLAs defined because we opted for enterprise support pricing.
We are not getting quick responses from Fastly technical support engineers.
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.
Seamlessly handling massive traffic without requiring backend changes due to its globally distributed Edge network and stateless API-driven design.
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.
Highly reliable for enterprise-scale applications with high uptime guarantees.
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 chose 8 out of 10 because it has excellent performance and low latency delivery, making it suitable for larger applications, with strong Edge Caching and instant purging capabilities.
Fastly could improve by improving the documentation and having some code examples.
Fastly should provide features similar to Cloudflare regarding a block list.
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.
It operates on a pay-as-you-go structure, but costs scale with traffic, requiring monitoring to avoid unexpected spikes based on data transfers and the number of requests handled.
In terms of price, I find it good.
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.
The best feature that Fastly offers is the Edge location, which reduces latency, making our applications work smoother because we do not have to constantly call the backend.
Fastly has a wide number of configuration features that can be performed, and I emphasize that they can be done from code, which makes it much more traceable.
In this project, it is working as a reverse proxy for CDN and WAF, web application firewall, additionally image optimization.
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.
