Focus slides: Virtualization, Hypervisors (KVM, Xen, ESXi), Instance Families (Compute vs. Memory vs. Storage optimized). The 2021 update adds a comparison table of , acknowledging that IaaS now includes "Metal as a Service" for legacy or high-compliance workloads.

PaaS maximizes developer productivity. It shifts focus from system administration to rapid application design and code deployment. Software as a Service (SaaS)

Future Trends (Edge-Cloud Integration, Serverless Computing, and Multi-Cloud Interoperability) Share public link

Universities and academic portals often host structured slide sets that break the book into units. The 2021 update adds a comparison table of

The infrastructure is shared by several organizations that have shared concerns (e.g., mission, security requirements, policy, and compliance considerations).

: Capabilities can be elastically provisioned and released. This allows applications to scale rapidly outward or inward commensurate with workload requirements.

A consumer can unilaterally provision computing capabilities, such as server time and network storage, as needed automatically without requiring human interaction with each service provider. IV. Measured Service (Pay-per-Use) Software as a Service (SaaS) Future Trends (Edge-Cloud

Comparing cloud to electricity grids, the PPT emphasizes . The 2021 update includes a new slide on Tiered Pricing (On-Demand, Spot, Reserved, and Savings Plans), illustrating how the principle of "pay only for what you use" requires sophisticated forecasting to avoid bill shock.

The cloud infrastructure is provisioned for open use by the general public. It exists on the premises of the cloud provider. Private Cloud

Buyya’s paradigm structures the cloud ecosystem into hierarchical layers. Each layer abstracts the complexities of the underlying infrastructure.

: Cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service (e.g., storage, processing, bandwidth, and active user accounts). 2. Service and Deployment Models

Based on the structure and content of Buyya’s text, the following principles emerge as fundamental:
