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
