What Is Cloud Computing
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:
3 Service Models
5 Essential Characteristics
4 Deployment Models

SaaS, PaaS and IaaS
Software as a Service
Applications delivered as a service
to end-users over the Internet
Platform as a Service

Choose Cloud Strategically
Is there a G-Cloud?
• In G-Cloud we define a “Private Cloud” as an
infrastructure dedicated to government most likely
amalgam of several compute utilities targeted to
improve citizen services. Therefore it is a hybrid cloud
comprised of both private and public deployment
models.
