Cloud Computing: Principles and Paradigms — Draft Content (based on Rajkumar Buyya, PPT 2021)

Overview

Cloud computing delivers on-demand computing resources (compute, storage, network, applications, services) over the internet with pay-per-use economics, elasticity, and managed operations. Core principles include virtualization, resource pooling, scalability, elasticity, multi-tenancy, measured service, and broad network access. Paradigms span service models (IaaS, PaaS, SaaS), deployment models (public, private, hybrid, community), and emerging models (serverless, edge, fog, cloud-native).

1. Scalability: Cloud computing resources can be scaled up or down to match changing business needs.
2. Cost Savings: Cloud computing eliminates the need for capital expenditures on hardware and software.
3. Increased Efficiency: Cloud computing automates many administrative tasks, freeing up IT staff to focus on strategic initiatives.
4. Improved Collaboration: Cloud computing enables collaboration and communication among teams, regardless of location.

Cloud Deployment Models

On-Demand Self-Service: Users can provision computing capabilities—such as CPU time, network storage, and software services—automatically, without human interaction with the service provider. Cloud Computing: Principles and Paradigms — Draft Content

Software as a Service (SaaS): Delivering applications over the web (e.g., Google Workspace, Salesforce). Scalability : Cloud computing resources can be scaled
