The document discusses the evolution of cloud computing and platforms as a service (PaaS). It states that by 2020, over 80% of computing will take place on public clouds. It outlines different types of cloud deployment models and service models. It then discusses the limitations of early approaches to cloud computing (Cloud 1.0) that still required extensive IT resources and how later approaches (Cloud 1.5) began to abstract away some complexity. It presents CloudBees' vision of Cloud 2.0 PaaS that applies cloud concepts directly to applications and data, providing frictionless development and deployment without requiring any IT resources. The document introduces CloudBees' developer and runtime services that aim to offer a complete application lifecycle platform
