Abstraction The absolute details of cloud system

implementation are hidden from users and developers

The applications are run on physical systems that are not specified

The administration of physical systems can be outsourced to 3rd party

The data is stored in locations that are unknown

Virtualization Systems are virtualized by polling

and sharing of resources Storage can be provided as needed

from a centralized infrastructure Costs are assessed with a “Pay-as-

you-use” model Resources are scalable

Cloud Architecture

Deployment Architecture

Cloud Features Massive Scalability Highly Reliable & Fault Tolerant Instant Application deployment Intra and Inter-cloud load balance Highly virtualized and standardized

infrastructures

Cloud Advantages No need to install or update Software

or Hardware Access from any browser and any

where Unlimited Use Always On Excellent Service Quality

Cloud Disadvantages Security – Companies might not be

comfortable handing over their sensitive data to a third party.
