This document discusses keeping cloud computing secure and cost effective. It defines cloud computing as a model for flexible internet-based consumption and delivery of computing resources. It outlines the key aspects of cloud computing including software as a service (SaaS), platform as a service (PaaS), infrastructure as a service (IaaS) and different delivery models. It emphasizes that the cloud requires management to identify risks, save costs through techniques like DevOps, leverage abstraction and flexibility, and ensure compliance.
