Cloud Computing MCQ Quiz

Cloud Computing Overview

• Cloud computing provides abstraction by combining physical resources, presenting them as virtual resources to users.
• It represents a new model for resource allocation for applications while ensuring platform-independent user access.

Key Concepts

• Essential Concept: Abstraction is critical in cloud computing, facilitating the separation of system details from users and developers.
• Service Composition: Cloud services comprise Platform, Software, and Infrastructure.

Customer Relationships

• Cloud services maintain a one-to-many relationship with customers, indicating multiple users can utilize the same service.

Platform Independence

• Cloud computing enables access to applications as utilities rather than requiring local installation, enhancing the mobility and collaboration of business applications.

Service Models

• The most refined and restrictive service model is Platform as a Service (PaaS), where clients utilize a complete hardware/software/application stack.

Internal Cloud Definition

• An internal cloud operates behind a corporate firewall, providing secure access and management of cloud resources.

Common Misconceptions

• Although cloud computing applications share resources, some approaches may utilize a strictly hardware-based approach to abstraction, countering the notion of exclusive virtualization.

Security in Cloud Models

• The cloud cube model identifies two types of security threshold values influenced by network firewalls.

Virtualization Types

• Storage, Application, and CPU virtualization are essential characteristics of cloud computing, emphasizing the need for flexible and configurable resources.
