Cloud Computing -
meaning and Definition
Cloud Computing
Meaning
Ravindra Dastikop
Cloud Computing
● Cloud Computing is a New
paradigm for delivering and
availing computing resources.
OLD paradigm: mainframe, PC, LAN
Ravindra Dastikop
Cloud Computing: Simplified Cloud computing is a model of delivering computing
resources from the Internet to the user.
Example
Example
Computing resources: basic and more
Basic:
hardware, platform and software
More:
any combination of above
Ravindra Dastikop
Computing ResourcesComputing resources include
● Networks
● servers,
● storage
● application
● service
Ravindra Dastikop
Cloud Applications
Cloud Computing is New
● It overcomes the need for buying
resources, instead makes them
accessible as free/ rental
resources
Ravindra Dastikop
Cloud Computing is New ●
Ravindra Dastikop
It’s liberator
● Cloud computing liberates user
from ownership, maintenance,
upgrade.
● Users just focuses on “ consuming”
Ravindra Dastikop
3. Resource pooling- location-independent, multi-tenancy-
Cloud Computing is New
● New in terms of combining
existing technoloies
○ Virtualization , networks -
existed for long
Ravindra Dastikop
It’s democratic
● Cloud computing removes the
barriers and makes computing
available to anyone, anywhere,
anytime.
Ravindra Dastikop
4. Rapid elasticity - scaling up to meet requirement
Definition
Elements of Definition
Ravindra Dastikop
Model Cloud computing is model.
● models are abstarctions of real
world
● Example: RDMBS, OSI
Ravindra Dastikop
FunctionCloud computing is model for
network access to computing
resources
Ravindra Dastikop
Enabler Cloud computing is model for enabling
● ubiquitous- everywhere- home, college,
station
● Convenient- easy - ATM
● on-demand - no working
● hours/holidays
Ravindra Dastikop
Shared Pool shared pool of configurable computing
resources
eg. like a place in parking lot
college library
Ravindra Dastikop
Configurable
configurable computing resources
In all sizes and for all sizes
Ravindra Dastikop
Rapid Provision
Rapidly provisioned and
No delay:
like mobile recharge
Tata Sky recharge
Ravindra Dastikop
Software Managed ● Released with minimal management effort or
service provider interaction○ Automatic and not manual
Ravindra Dastikop
Time to Define cloud computing
Definition- NIST Cloud computing is model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources that can be rapidly provisoned and released with minimal management effor or service provider interaction

Topic
Ravindra Dastikop
Characteristics of Cloud Computing
Characteristics of Cloud Computing ● On demand self service
● Broad network access
● Resource Pooling
● Rapid Elastcity
● Measured Service
Ravindra Dastikop
● On demand self service
● On-demand self service refers to the service provided by cloud computing vendors that enables the provision of cloud resources on demand whenever they are required.
Ravindra Dastikop
Broad network accessThe term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access.
Ravindra Dastikop
Resource Pooling
● Pooling is a resource management term that refers to the grouping together of resources (assets, equipment, personnel, effort, etc.) for the purposes of maximizing advantage and/or minimizing risk to the users.
Ravindra Dastikop
Rapid Elasticity● Elasticity is
defined as the
ability to scale
resources both
up and down as
needed
Ravindra Dastikop
Measured Service
measured service as a setup where cloud systems may control a user or tenant’s use of resources by leveraging a metering capability somewhere in the system
Ravindra Dastikop
Other Characteristics ● Performance
○ reduced costs
○ outsourced management
○ reliability
○ multi-tenancy
