3. Cloud computing is the further enhancement and development of grid
computing, parallel computing and distributed computing.
Cloud symbolizes the web as a space where the computing is preinstalled and
exists as a service.
To the users, cloud computing plans are Pay-as-you-go (or) Pay-Per-Use-
On-Demand mode.
Cloud computing is based on the concept of virtualization, utility computing,
Infrastructure as a Service (IaaS), Platform as a Service (Paas), Software as a
Service (Saas), Data as a Service (Daas) and Anything as a Service (Aaas).

6. The basic strategy of IaaS is virtualization of machines
independently. Hardware resources (storage) computing power (i.e.
CPU and Memory) are offered as a service to customers.
IaaS
Examples of IaaS are Amazon offers S3 for storage, EC2 for
Computing power, Microsoft, etc.
Hard

7. Cloud computing provides facilities to support the entire application
development lifecycle including design, implementation,
debugging, testing, deployment, operations and support for Rich
web applications and services on the internet.
PaaS
Examples of PaaS are Microsoft Azure Services Platform,
Google App engine, Salesforce.com, etc.
Testers

8. Software applications are offered as a Service on the internet rather
than a software packages to be purchased by individuals. Web
accessible software enables users to use programs or applications
without having to download or install them on their machines.
SaaS
Examples of Saas are Google web-based office applications (word
processor, spreadsheets), Microsoft online CRM and SharePoint,
Salesforce.com, etc.

9. A more specialized type of storage, offering database capability as a
service. It can be considered as a sub-organisation of IaaS, DaaS on
the cloud often adopts a multi-tenant architecture, where the data of
many users is kept in the same physical table.
DaaS
Examples of DaaS are Amazon S3, Microsoft SSDS, Google Big
Table, Apache HBase and Apache Pig, etc.

the real world to get rid of the drawbacks of that any particular
issues in cloud computing.
A most specialized type of SaaS which is to be adopted for
particular special tasks.
For example a security service provider can be hired to protect the
data in common cloud which is to payed by the clients.

11. The biggest concern about cloud computing are security and privacy.
To make their servers more secure, cloud service vendors have developed password
protected accounts, security server through which all data being transferred must
pass and data encryption techniques.
The input data for cloud services is uploaded by the user to the cloud, which means
that they typically result in user’s data being present in unencrypted form on a
machine that the user does not own or control.
There is a risk of data theft from machines in the cloud, by rogue employees of
cloud service providers (or) by data thieves breaking into service providers
machines.

12. Our view about the cloud is that if a single person is technically
skilled, person can directly compete with existing business system.

14. This paper discusses the basic architecture of the cloud and
the improvements done in the services such as Daas and
Aaas. The Powerful Business Tool role is performed by the
cloud as it energies the competitive power of small and
medium enterprises to compete with the huge IT giants. The
further study of cloud revel’s the Cloud Era where the
computing is the world. The future of the computing is the
virtualization of the services and it is the perfect cloud
where all the drawbacks has been eradicated still there’s
always interesting topic is cloud as the revolution takes in
the generations of the computers it may too happen in the
future.
