Study Notes

Cloud Computing Overview

Cloud computing is a model for enabling on-demand network access to a shared pool of configurable computing resources.

Essential Characteristics of Cloud Computing

According to the United States National Institute of Standards and Technology, the five essential characteristics of cloud computing are:
- Resource Pooling: Resources are pooled to provide a multi-tenant environment.
- Broad Network Access: Resources are accessible over the network and can be accessed through standard mechanisms.
- On-Demand Self-Service: Automatic control and customization of resources through a self-service portal.
- Rapid Elasticity: Resources can be rapidly scaled up or down to match changing business needs.
- Measured Service: Resource usage is metered and billed accordingly.

Pay-As-You-Go Model

The pay model typically used in cloud computing is a pay-as-you-go model, where users only pay for the resources they use.

Coherence in Cloud Computing

Cloud computing achieves coherence through standardization, virtualization, and distribution of resources.

Matching Characteristics with Descriptions

On-Demand Self-Service: Automatic control and customization of resources through a self-service portal.
Rapid Elasticity: Resources can be rapidly scaled up or down to match changing business needs.
Resource Pooling: Resources are pooled to provide a multi-tenant environment.

Reducing Capital Expenses

Cloud computing helps reduce capital expenses by providing on-demand access to resources, eliminating the need for upfront capital investments.

Matching Cloud Computing Components with Descriptions

Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet.
Platform as a Service (PaaS): Provides a complete platform for developing and deploying applications.
Software as a Service (SaaS): Provides software applications over the internet.

Matching Terms with Definitions

Public Cloud: A cloud computing environment open to the general public.
Private Cloud: A cloud computing environment dedicated to a single organization.
Hybrid Cloud: A cloud computing environment that combines public and private clouds.

Matching Devices with Client Platforms

Desktop Computer: A personal computer used as a client platform.
Mobile Phone: A handheld device used as a client platform.
Laptop: A portable computer used as a client platform.

Matching Cloud Computing Models with Characteristics

Infrastructure as a Service (IaaS): Provides virtualized computing resources over the internet.
