Should Consul instances be placed behind a load balancer

[erich oliphant]

Hi, I'm working with Consul on AWS and I've been using the ec2 tag support to get the cluster up, clients and servers talking, etc.  However, there are still instances where I might need to point directly to a server, say running some scripts that aren't on an EC2 instance, etc.  Does it makes sense to just sit them behind an ELB so that there's a well-known address for non-EC2 clients?

Hi, in general it's still best to try to run the agent everywhere and
have your applications talk to their local agent. That way if you
register services there you automatically get the serfHealth check for
that agent from the cluster, automatic management of finding a healthy
Consul server, etc. If you can't run an agent then it's ok to run the
ELB (we have some folks that only care about KV, for example, who do
this).
