This document discusses the evolution of Intalio's software deployment approach from bare metal servers to Platform as a Service (PaaS). It describes how Intalio initially deployed software on their own servers (DIY), which led to scaling issues. They then moved to Infrastructure as a Service (IaaS) on AWS, but still faced complexity issues. Intalio then adopted PaaS using Cloud Foundry for "NoOps", allowing them to focus on development instead of operations. The document examines deploying applications to PaaS and how distributed architectures can be built on a PaaS.
