The document discusses the five pillars of cloud computing: parallelism, modularity, horizontal scalability, agility, and security. Parallelism allows distributing workloads across multiple computing resources to improve performance. Modularity involves designing systems as independent and interchangeable modules to improve maintainability. Horizontal scalability is the ability to increase system capacity by adding more commodity hardware. Agility refers to the ability to rapidly and repeatedly make changes to a system. Security must be implemented throughout all layers of a cloud application or system.
