IronFunctions LoadBalancer

Loadbalancing several IronFunctions

You can run multiple IronFunctions instances and balance the load amongst them using fnlb as follows:

fnlb --listen <address-for-incoming> --nodes <node1>,<node2>,<node3>

And redirect all traffic to the load balancer.

NOTE: For the load balancer to work all function nodes need to be sharing the same DB.

# Functions

ConsistentHashReverseProxy

ConsistentHashReverseProxy returns a new ReverseProxy that routes URLs to the scheme, host, and base path provided in by a consistent hash algorithm.

NewRoundTripper

NewRoundTripper creates a new FallbackRoundTripper and triggers the internal host TCP health checks.

# Variables

ErrNoFallbackNodeFound

ErrNoFallbackNodeFound happens when the fallback routine does not manage to find a TCP reachable node in alternative to the chosen one.

# Structs

FallbackRoundTripper

FallbackRoundTripper implements http.RoundTripper in a way that when an outgoing request does not manage to succeed with its original target host, it fallsback to a list of alternative hosts.
