MODULE 13: NETWORK VIRTUALIZATION
13.1 Cloud Computing
13.1.1 Video - Cloud and Virtualization
13.1.2 Cloud Overview
Cloud computing addresses a variety of data management issues:
Enables access to organizational data anywhere and at any time
Streamlines the organization’s IT operations by subscribing only to needed services
Eliminates or reduces the need for onsite IT equipment, maintenance, and management
Reduces cost for equipment, energy, physical plant requirements, and personnel training needs
Enables rapid responses to increasing data volume requirements
13.1.3 Cloud Services
13.1.4 Cloud Models
13.1.5 Cloud Computing versus Data Center
Data center: Typically, a data storage and processing facility run by an in-house IT department or leased offsite.
Cloud computing: Typically, an off-premise service that offers on-demand access to a shared pool of configurable computing resources. These resources can be rapidly provisioned and released with minimal management effort.
