HAProxy Edge Load Balancer Featured
The reference software load balancer, one click into any PoP.
HAProxy (High Availability Proxy) is the de facto reference open-source load balancer and reverse proxy, trusted to front some of the busiest sites on the internet. It provides layer 4 (TCP) and layer 7 (HTTP) load balancing, health checking, TLS termination, and content-aware routing in a single, extremely efficient event-driven process.
Key features
- Layer 4 and layer 7 load balancing with many algorithms (round-robin, leastconn, hashing, and more)
- Active and passive health checks with automatic failover for high availability
- TLS/SSL termination and re-encryption, SNI routing, and modern cipher control
- Content switching and ACL-based routing on host, path, headers, or cookies
- Built-in HTML statistics dashboard (commonly port 8404, path /stats) with CSV export
- HTTP/2 and HTTP/3 (QUIC) support, connection pooling, and request rate limiting
- Runtime API and reloadable config for zero-downtime changes
- Observability via a Prometheus metrics endpoint and detailed logging
Use cases
- Distributing web and API traffic across a pool of application servers
- High-availability TCP load balancing for databases, message queues, and custom protocols
- TLS termination and edge reverse-proxy in front of microservices
- Blue/green and canary rollouts using content switching and weighted backends
Why run it on the NetActuate edge Terminating TLS and load balancing in a PoP near users shortens the TLS handshake and round-trip path for faster responses. Edge health checking routes around unhealthy origins while keeping the client connection local and low-latency, and running HAProxy across anycast PoPs spreads traffic and burst load close to the source instead of concentrating it at one origin.
Frequently asked questions
How do I deploy HAProxy Edge Load Balancer on NetActuate?
Use the Deploy on NetActuate button to talk to our team. We provision HAProxy Edge Load Balancer on a NetActuate virtual machine in the point of presence you choose, close to your audience. Each deployment runs in the single location you select.
What does it cost to run HAProxy Edge Load Balancer?
HAProxy Edge Load Balancer is open-source software and free to run on the marketplace - you pay only for the NetActuate compute (virtual-machine size and location) it runs on, at standard rates. There are no usage-based software fees.
Where can HAProxy Edge Load Balancer run?
HAProxy Edge Load Balancer can be deployed in any of NetActuate's 45+ points of presence across every continent, so you can place ingest, transcode, delivery and caching close to your contributors and viewers.
Who supports HAProxy Edge Load Balancer?
NetActuate operates and supports the underlying infrastructure - the virtual machine, network and edge platform. The application itself is supported by its upstream open-source project.
