Cloud Computing Definition
“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 five essential characteristics, three delivery models,
and four deployment models”.

What Should a Cloud Be?
• Provide zero touch services to cloud
customers
• Run a data center like a modern factory
• Reduce headcount
• Provide the appearance of unlimited
resources
• An environment resources no servers
• Provides ephemeral thinking
• Governs and brokers resources
