Main characteristics ofCloud Computing architectureareas follows:
I. Elasticity :InCloud Computing systemis highly elasticin thesensethat itcan easily adapt itselfto increase or decreasein load.
Thereis no need to take urgentactions when thereis surgein trafficrequests.
II. Self-service provisioning :InCloud environment userscan provision newresources on their own by justcalling some APIs.
Thereis no need to fillformsand orderactual hardwarefromvendors.
III. Automated de-provisioning :In case demand/load decreases,extraresourcescan beautomatically shut down inCloud
computing environment.
IV. Standard Interface :Therearestandard interfaces to start, stop, suspend or removean instanceinCloud environment. Most of
theservicesareaccessible via publicand standard APIs inCloud computing.
V. Usage basedBilling :In a Cloud environment, usersarecharged for their usage ofresources. They can forecast their billand
costs based on the growth they areexpecting in their load.
