What is Cloud Computing ????
Cloud computing is Internet-based computing, whereby shared
resources, software, and information are provided to computers and other
devices on demand.
Cloud computing provides computation, software, data access, and
storage services that do not require end-user knowledge of the physical location
and configuration of the system that delivers the services.

Characteristics of a Cloud Environment
• Dynamic- One of the keys to cloud
computing is on-demand provisioning
• Massively scalable- The service must
react immediately to your needs
• Multi-tenant- Cloud computing, by its
nature, delivers shared services

Characteristics of a Cloud Environment
• Self-service - As a user, you can use
the service as you require
• Per-usage based pricing model - You
should only ever pay for the amount
of service you consume.

Types of Cloud
• Public Cloud – Available to the general public or
large industry group and is owned by an
organisation selling cloud services
• Community Cloud – Shared by several
organisations and supports a specific community
that has shared concerns
• Private Cloud – Operated solely for an organisation
or company
• Hybrid Cloud – Combination of two of the above,
they remain unique entities but are bound
together by standardised technologies
