ROI

Sentiment score
7.2
Azure DDoS Protection offers cost-effective security for public IPs, benefiting users with ROI despite varying enterprise costs.
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.

Room For Improvement

Azure DDoS Protection requires improved interface consistency, reporting, configuration simplicity, bandwidth optimization, enhanced services, and AI-driven auto-remediation.
HAProxy needs a revamped GUI, improved APIs, better AWS integration, real-time config, enhanced docs, and stronger monitoring and security.
It would be beneficial to have more detailed insights available directly on the dashboard.
Cloud Architect at Vision Bank
I have noticed some false positives with the Web Application Firewall yet not with DDoS Protection.
Azure Consultant at cloudshift
I suggest adding more services and additional services, which would be beneficial.
Senior Manager at Ernst & Young
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.

Setup Cost

Azure DDoS Protection offers expensive but comprehensive protection with trial, special pricing for education, and no extra fees for some uses.
Enterprise users value HAProxy's competitive pricing and cost-effective licensing, especially compared to F5 and Citrix, despite initial setup costs.
If used with Front Door or Web Application Firewall, DDoS Protection is included without additional cost.
Azure Consultant at cloudshift
The pricing is somewhat costly, usually around $3,000 to $4,000 per month.
Cloud Architect at Vision Bank
Compared to competitors, it is good.
Senior Manager at Ernst & Young
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.

The integration of various tools with Azure Firewall, like DDoS Protection, Web Application Firewall, and Azure Front Door, is quite effective.
Azure Consultant at cloudshift
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.

Security architecture shields infrastructure but dashboard needs enhancement
The Azure DDoS Protection plan is essential for environments like ours that are highly exposed to potential attacks, especially since DDoS attacks have become common. The security architecture with Azure DDoS Protection is critical for safeguarding our financial organization's infrastructure. Although implementing it is pricier, it is worth using since our applications are entirely in Azure.
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.
