What Are Load Balancing Algorithms? All You Need To Know

Picture a restaurant host seating incoming guests in different parts of the restaurant to distribute the workload among the waitstaff. The host aims to ensure that no single server feels overwhelmed or becomes responsible for more tables than they can handle. This process also means guests receive timely service.

Reverse Proxy: How It Works, Examples, and Use Cases

In networking, a proxy acts as a middleman between the client and the server, managing requests and responses on behalf of the other devices.

Question on: HAProxy

What do you actually get with the Enterprise load balancer that you don't get with the open source version?

We're comparing the open source and Enterprise options and want a practical view of the difference. Which features, management tools, security capabilities, and support services make the Enterprise edition worth considering?

You keep the same high-performance open source core and add the layers you need to run it in production. The HAProxy Enterprise load balancer adds production modules for security and traffic management, such as a WAF, bot management, DDoS protection, and GSLB, plus 24/7 support recognized with G2 Best Relationship awards across every load balancing segment. It also includes the HAProxy Fusion Control Plane, which handles full-lifecycle management across your whole fleet: monitoring with over 150 runtime and security metrics, automated updates, role-based access control, and customizable dashboards, all through a GUI and an API with complete coverage of HAProxy Enterprise configuration. Put simply, the open source core gives you the fundamentals, and Enterprise adds production-grade modules with their own engines, like the Intelligent WAF Engine, plus the support to run it reliably at scale.

Question on: HAProxy

Is HAProxy just a load balancer, or is it a full platform these days?

I've mostly known HAProxy as a load balancer, but its capabilities seem to have expanded. I'm trying to understand what the broader platform includes today and which use cases it can support beyond traffic distribution.

Load balancing is the core, but HAProxy One is a full application delivery and security platform. Alongside high-performance load balancing, it provides an API and AI gateway, Kubernetes routing, SSL/TLS processing, and multi-layered security, all managed from one control plane. That breadth shows up in HAProxy's G2 standing: it's a Leader in categories from WAF and DDoS Protection to Container Networking and API Management. Teams consolidate onto it for performance and reliability at scale. HAProxy handles millions of requests per second at low latency on a single instance, and holds a perfect 100 satisfaction score in Load Balancing that no other product in the category matches.

Which load balancing solutions have real-time health checks and automatic failover for redundant servers?

Hello G2 folks, we're looking at load balancers with real-time health checks and automatic failover across redundant servers, so a dead backend never reaches a user. What we're hoping to find:

Continuous health checks that catch a failing server fast
Automatic failover to healthy nodes with no manual step
Confidence it works before we actually need it

From the load balancing category:

AWS Elastic Load Balancing: health checks route only to healthy targets and redirect on failure automatically.
Google Cloud Load Balancing: reviewers say it continuously checks server health so only healthy servers get traffic.
Progress Kemp LoadMaster: health monitoring and templates give a quick read on virtual service health.
HAProxy: sophisticated health checks reviewers credit with removing unhealthy servers before users hit errors.
Azure Application Gateway: backend health checks that confirm whether servers are up.

For teams relying on this, whose health checks and failover actually caught a real outage? And how did you test failover before trusting it in production?

The way most teams actually test this, deliberately killing a server to confirm failover triggers, tests a different failure mode than the one that usually causes real damage. A killed server produces an unambiguous signal, no response at all, which a basic health check catches easily. The dangerous case in production is a server that's still technically answering health checks, still returning HTTP 200, but serving degraded or wrong results to real users, a "gray failure" that a simple health check configuration won't catch at all, since it's checking whether the server responds, not whether the response is actually correct. So "confidence it works before you need it" from a deliberate test and "it actually caught the outage that mattered" can be two different claims, and the gap between them is usually the health check's depth, whether it's just checking liveness or actually validating response correctness.
