From the Gilliam website:
Gilliam is a open source Platform as a Service (PaaS) that allows you easily develop, deploy and scale your application backend. Unlike commercial
and many other open source PaaS systems, Gilliams is intended for Micro Service Architectures.
Gilliam stands on the sholders of Docker. Every piece of code running on Gilliam is a Docker image. To that Gilliam adds service discovery, a router,
scheduling and elastic scaling.
