HAProxy 2.8 LTS with Keepalived for a floating IP across a HA pair, SSL termination, sticky sessions, HTTP/2, active health checks, and a Prometheus exporter wired into Grafana. Up to 8 backend pools and 64 servers per pair.
HAProxy is the load balancer that the rest of the internet is built on. We deploy 2.8 LTS with a config tuned for modern web traffic: HTTP/2 at the edge, TLS 1.3 with strong ciphers, active health checks against your backends, circuit breaking when they misbehave, and sticky sessions via cookie or source IP for stateful apps.
For high availability, add the active/passive pair option (+$15/mo). Keepalived runs VRRP between two HAProxy nodes, exposing a floating IP that fails over in under 3 seconds if the primary disappears. Your backend keeps serving without anyone noticing.
TLS certificates from Let's Encrypt are issued and renewed unattended. The HAProxy Stats UI is reachable over TLS at a non-default path, with HTTP basic-auth and rate limiting. The Prometheus exporter exposes every metric HAProxy publishes so you can build SLO dashboards in Grafana.
Route to up to 8 backend pools with up to 64 servers each. Plenty of room for blue-green and canary patterns.
Per-backend HTTP/HTTPS/TCP checks. Bad nodes are drained automatically; recovered nodes rejoin gradually.
TLS 1.3 with strong ciphers, HTTP/2 at the edge, OCSP stapling. A+ on SSL Labs out of the box.
Cookie-based or source-IP affinity for stateful applications. Configurable per pool.
Keepalived + VRRP across two HAProxy nodes with a floating IP. Sub-3-second failover, transparent to clients.
HAProxy Stats UI for live state, Prometheus exporter for Grafana dashboards and SLO alerting.
$24.99/mo for the managed HAProxy stack + the server it runs on. Add the HA pair option for +$15/mo.
HAProxy with TLS, health checks and stats — ready in minutes. Add HA failover for $15/mo extra.
