4. NIST Definition of Cloud Computing
Cloud computing is a model for enabling convenient,
on-demand network access to a shared pool of
configurable computing resources (e.g., networks,
servers, storage, applications, and services) that can be
rapidly provisioned and released with minimal management
effort or service provider interaction.
This cloud model promotes availability and is composed of:
5 Essential Characteristics 3 Service Models 4 Deployment Models
• On-demand self-service • SaaS • Public Cloud
• Resource pooling • PaaS • Private Cloud
• Rapid elasticity • IaaS • Community Cloud
• Measured service • Hybrid Cloud
• Broad network access
