Description
OrangeGrid Cloud Workers is the infrastructure that lets Syracuse University's on premises HTCondor cluster overflow into public cloud spot instances when campus capacity runs out. A researcher submits a job the same way they always have, condor_submit my.sub from a campus submit host, and if the job opts in with +WantCloudBurst = "...", it can land on an ephemeral VM running in any public or participating private cloud. The cloud VM joins the cluster as a regular HTCondor execute node, mounts the user's NFS home directory, authenticates with campus LDAP, and runs the job. When the spot instance is reclaimed, another worker takes over. No new tooling for users, no data migration, no second workflow.
This solves a specific problem. Campus compute is finite, demand isn't. Cloud bursting can help with this. The hard part is doing it without breaking the user facing contract around homedirs, UIDs, and job submission.
