Services are available over the network and accessed through standard mechanisms (e.g., internet browsers, mobile apps). 2. Evolution of Cloud Computing Paradigms (2021 Update)

: Resources can be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand. Measured Service

Based on the textbook " Cloud Computing: Principles and Paradigms

First published by (with a 1st edition release in December 2010 and subsequent reprints, including a notable 2021 catalog listing), the book spans 664 pages across 25 chapters and remains a cornerstone reference for the field. Services are available over the network and accessed

The benefits of cloud computing, as highlighted by Rajkumar Buyya, include:

6. Advanced Paradigms: SLA Management and Market-Oriented Computing

Offers fundamental computing resources like virtual machines, storage, and networks. Measured Service Based on the textbook " Cloud

This is the cornerstone technology. It involves abstracting physical hardware (servers, storage, networking) into virtual machines (VMs) or containers, allowing multiple workloads to share resources efficiently.

Multi-tenancy ensures that despite sharing the same hardware, different users' data and workloads remain strictly isolated and secure. Elasticity and Scalability

: Users interact solely with the client interface. The infrastructure, operating systems, and application backend are hidden. Examples : Microsoft 365, Google Workspace, and Salesforce.

Efficient resource allocation prevents SLA (Service Level Agreement) violations while keeping provider costs low.

: Run directly on the host's physical hardware (Bare-metal). Highly efficient and used in enterprise public clouds.

Abstracting infrastructure entirely away from developers, executing code blocks instantly in response to real-time events. Summary for Presentation Slides
