The document outlines the five pillars of cloud computing: parallel, modular, horizontal, agile, and secure. It describes each pillar in detail with examples. The parallel pillar discusses distributing workloads across multiple nodes. The modular pillar explains how separating applications into independent modules improves scalability and maintainability. The horizontal pillar refers to scaling out additional computing resources. The agile pillar demonstrates how cloud supports rapid, frequent delivery of updates. And the secure pillar stresses security across all layers of cloud applications and infrastructure.
