- The year 2009 saw a huge interest in cloud computing and the World financial crisis in 2007-2008 was the biggest influence in creating the cloud hype initially.
Fundamental milestones towards cloud computing in the history of computing,

NIST's definition of Cloud Computing, "Cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (eg. networks, servers, storage, applications and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction".
Data center resources that can be offered through cloud computing are (DNS),
- Data storage,
- Network bandwidth
- Server,
- What gives cloud end users access to request resources?
Service catalog in web portal - What is elasticity according to NIST definition of cloud computing?
Cloud capabilities can be scaled rapidly out-ward and inward according to demand. - What defines best as the opposite of NIST essential characteristic "resource pooling" for cloud computing?
Silos - The following options are direct benefit from cloud computing measured service characteristic? ART
- Automatic control,
- Resource optimization,
- Transparency between provider and consumer.
- The following options represent devices that can utilize cloud resources,
Personal computers, Tables, Mobile phones. - What is a tenant in the context of cloud computing?
Any application that requires isolation from other tenants. - NIST classifies cloud implementations into?
- Deployment models (Public, Private, Hybrid)
- Service models (Iaas, Paas, Saas)
