2. THE MOST ADVANCED TECHNOLOGY
THAT WHICH ENABLES THE IT
RESOURCES WITHOUT ANY
INFRASTRUCTURES.
THAT MEANS FOR ANY IT COMPANY, WE
NEED A SERVER ROOM THAT IS THE
BASIC NEED OF IT COMPANIES.
CLOUD COMPUTING ENABLES
COMPANIES TO CONSUME A COMPUTE
RESOURCE, SUCH AS A VIRTUAL
MACHINE, STORAGE OR AN
APPLICATION, AS A UTILITY.

3. The history of cloud computing starts way back in the 1960s.
Over the course of the past decade, cloud computing has evolved
from being something service providers told companies they should
be adopting to becoming the technological lifeblood that runs
through most modern enterprises.
In 2002, Amazon started Amazon Web Services, providing services like
storage, computation and even human intelligence. However, only
starting with the launch of the Elastic Compute Cloud in 2006 a truly
commercial service open to everybody existed.

4. Self-service provisioning means the computing resources are used for almost
any kind of work.
Flexibility refers to changes in usage to increase or decrease as users see their
needs change.
Pay-per-use allows users to pay for only the services and resources they use.
Maintenance of the servers is easy. Servers are off site, and the providers take
care of software updates. There is no need for users to install software on to
individual systems and keep up to date with the software as it develops.
Location-free allows users to work from anywhere. As long as you have an
Internet connection you can access the cloud. Many providers often have apps
available to multiple devices, so you are not restricted.
 Backup. Cloud-based backup saves time, avoids larger investments and the
need to recruit third-party experts.
Cloud-based workload and file sharing streamline teamwork collaboration,
which allows data to be shared, accessed and edited from anywhere.

5. DISADVANTAGES
1) REQUIRE A CONSTANT INTERNET CONNECTION
Cloud computing is impossible without Internet connection. To access
any applications and documents you need a constant Internet
connection.
2) REQUIRE HIGH SPEED INTERNET CONNECTION
Similarly, a low-speed Internet connection makes cloud computing
painful at best and often impossible. Web based apps often require a lot
of bandwidth to download, as need to download large documents.
3) STORED DATA MIGHT NOT BE SECURE
With cloud computing, all your data is stored in the cloud. That's all well
and good, but how secure is the cloud? Can't unauthorized users gain
access to your confidential data?

6. HOW CLOUD COMPUTING WORKS
 instead of installing a suite of software for each computer, you just
need to load one application.
That application will allow the employees to log-in into a Web-
based service which hosts all the programs for the user that is
required for his/her job.
Remote servers owned by another company and that will run
everything from e-mail to word processing to complex data analysis
programs.
It is called cloud computing, and it could change the entire
computer industry.
cloud computing can handle that much heavy load easily and
automatically.

7. CLOUD COMPUTING DEPLOYMENT MODELS
Cloud computing services can be private, public or hybrid.
P R I V A T E
A cloud computing model in
which an enterprise uses a
proprietary architecture and
runs cloud servers within its
own data centre.
CHARACTERISTICS:
Single-tenant architecture on
premises hardware Direct
control of underlying cloud
infrastructure
TOP VENDORES:
HPE, Vmware,
DELL EMC., IBM.
H Y B R I D P U B L I C
A cloud computing model in
which a third-party provider
makes compute resources
available to the general public
cloud, enterprises do not have
to set up and maintain their
own cloud servers in house
CHARACTERISTICS:
Multi-terant architecture
Pay-as-you-go pricing model
TOP VENDORES:
AWS, MICROSOFT, AZURE,
GOOGLE CLOUD PLATFORM.
A cloud computing model that
includes a mix of on-premises,
private cloud and third-party
public cloud services with
orchestration between the two
platforms.
CHARACTERISTICS:
Cloud bursting capabilities
benefits of both public and
private environments
TOP VENDORES:
A COMBINATION OF BOTH
PUBLIC AND PRIVATE CLOUD
PROVIDERS

8. SOFTWAREASASERVICE-SaaS
 Applications are hosted by a cloud service
provider and made available to customers over
internet.
ADVANTAGES
 SAAS IS EASY TO BUY-SaaS pricing is based on a
monthly fee or annual fee, SaaS allows organizations to
access business functionality at a low cost which is less
than licensed applications.
 LESS HARDWARE REQUIRED FOR SaaS-The software
is hosted remotely, so organizations don't need to invest
in additional hardware.
 LOW MAINTENANCE REQUIRED FOR SaaS-Software
as a service removes the necessity of installation, set-up,
and often daily upkeep and maintenance for
organizations. Initial set-up cost for SaaS is typically less
than the enterprise software
CLOUD SERVICE MODELS DISADVANTAGES
 SECURITY-Actually data is stored in cloud, so security
may be an issue for some users. However, cloud
computing is not more secure than in-house
deployment. Learn more cloud security.
 LATENCY Issue-because the data and application are
stored in cloud at a variable distance from the end user,
so there is a possibility that there may be more latency
while interacting with the application than a local
deployment. So, SaaS model is not suitable for
applications whose demand response times are in
milliseconds.
 TOTAL DEPENDENCY ON INTERNET - Without
internet connection, most SaaS applications are not
usable.
 SWITCHING BETWEEN SAAS VENDORS IS
DIFFICULT -Switching SaaS vendors involves the difficult
and slow task of transferring the very large data files
over the internet and then converting and importing
them into another SaaS also.
