The architecture of cloud computing is traditionally structured into a three-layer stack, often referred to as the SPI framework: SaaS, PaaS, and IaaS.
A composition of two or more distinct cloud infrastructures (private, community, or public) that remain unique entities but are bound together by standardized technology enabling data and application portability. manage load balancing
Services are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms (e.g., mobile phones, laptops). Resource Pooling:
Cloud computing operates through a distinct hierarchy of service abstraction layers. Understanding these tiers is essential for designing any modern digital application. Infrastructure as a Service (IaaS) manage load balancing
While the foundational text establishes these principles, the 2021 landscape integrated these paradigms into more complex environments: Hybrid and Multi-Cloud

The core pillars (Virtualization, Multi-tenancy, and Orchestration engines).
Resources can be elastically provisioned and released—in some cases automatically—to scale rapidly outward and inward commensurate with demand. To the consumer, the capabilities available for provisioning often appear to be unlimited and can be appropriated in any quantity at any time. III. On-Demand Self-Service
Cloud environments do not rely on manual human intervention to provision servers. Automated software orchestrators monitor system health, manage load balancing, and provision or decommission storage and compute nodes in real-time based on predefined policies. 3. The SPI Service Model Spectrum
For those developing pieces or presentations based on Buyya’s work, consider these critical areas of focus: Energy Efficiency
