Thanks for the synopsis. Lots of plans for IronWorker including fully custom Docker image support (soon) and millisecond response times (soon'ish). We also support custom configurations of CPU/RAM for dedicated customers which is what most of our customers with stricter SLA's utilize.

That said, a big differentiator is IronWorker's ability to be deployed to any cloud provider as well as private clouds / on-premises. Many of our enterprise customers need hybrid deployments.

We're always listening so please feel free to shoot us feedback at support[at]iron.io or find us at @getiron.
