In theory, yes.

In practice, the artifact plugin does not like slow links at all: each
file requires a full round trip, so if you have lots of small files, the
latency of the link becomes a problem, and if you have big files, the
keepalive probes inside the agent protocol become queued behind
transfers, which might make the agent connection appear broken.

Also, any hiccup in the connection will fail running builds.

Re: Cloud Master / On-Prem Slave

[Mark Waite]

If your on premise agents (slaves) can connect to the JNLP port of the
cloud master (usually port 5), then they could be added as agents
(slaves) of your cloud master using the "Java Web Start" method.  That
requires the agent initiates the connection to the master JNLP port and the
master needs to be willing to accept the connection on that port.

If your cloud master can initiate an ssh connection to your on-premise
agents, then you could add the on-premise agents using the ssh-slaves
plugin.  That requires the master initiates the connection to the agent ssh
port and the agents need to be willing to accept the connection on the ssh
port.

Re: Cloud Master / On-Prem Slave

[Denis Mone]

We have our Jenkins master on a EC2 instance as well, and the slaves are
VMs in our office.
We have Jenkins communicate with them over OpenVPN (though VPC would be
preferable)

On the Jenkins side the agents are launched using the ssh-agents plugin.
Plain old ssh connection that is.

We have multiple offices around the globe and all of them use hit Jenkins
and it accordingly schedules jobs
on the said VMs.

Cloud Master / On-Prem Slave

[Steve B]

I am fairly new to Jenkins.  We have used it on-prem for some builds.
Development has started using Jenkins in the cloud for new features and I 
was wondering if I can have the Jenkins Master that is in the Cloud send 
jobs to my On-Prem slaves?

Looks like there are some services that allow some sort on "Hybrid" systems 
but I don't think we can go for that at this time.

Thanks
