4. WHAT IS CLOUD COMPUTING
• Cloud computing is Internet-based computing, an Internet based
computing environment where you pay only for resources that you
use .
• Cloud Computing provides the infrastructures (both software and
hardware) as services on a semi –permanent (rented) basic.
• A set of pooled computing resources delivered over the Internet.
• Resource allocation can be adjusted.

7. CLOUD COMPUTING - TYPE
Public cloud – Suitable for applying to general systems not particular
systems and serving massive clients and also cheap price.
Private cloud – Suitable for particular systems or needed high security
systems through cloud provider.
Hybrid cloud – This system is a composition of Public cloud and Private
cloud. It also use for transferring data from one to another cloud.

8. CLOUD COMPUTING-LAYER
Shailendra Singh

9. INFRASTRUCTURE AS A SERVICE (IAAS)
Entire systems (virtual machines) will be provided to the
users. Users can access the systems through internet
Service providers charge based on the resource allocated
Access to infrastructure stack:
 Full OS access
 Firewalls
 Routers
 Load balancing
Shailendra Singh

10. PLATFORM AS A SERVICE (PAAS)
In this model entire system along with the operating systems,
software is provided.
Platforms are built upon Infrastructure, which is expensive
Estimating demand is not a science!
Platform management is not fun!
Shailendra Singh

11. SOFTWARE AS A SERVICE (SAAS)
This one is more common Software created by service
provider.
End users use these services on a subscription basis
No hardware or software to manage
Service delivered through a browser
Shailendra Singh

12. CLOUD ARCHITECTURE
Individual users connect to the cloud from their
own personal computers or portable devices, over
the Internet. To these individual users, the cloud
is seen as a single application, device, or
document.
The hardware in the cloud (and the operating
system that manages the hardware connections)
is invisible.

19. For those who follow trends in web hosting, cloud computing is
a term that they come across often these days. There are
many benefits of cloud computing irrespective of the size of
the organization. The benefits include secure and affordable
managed hosting, accessibility of data from anywhere at
anytime, offsite backup, no need of internal IT
resources, scalability and so on.
But there are some limitations as
well since it is still an evolving
technology. Some weaknesses of
cloud computing are listed below:

20. LIMITATIONS
• Control of Data Security
• Hard to log for compliance
• Cascading effect
• Network Connection
• Large companies have internal cloud
• Dependent on service providers even for trivial
applications.

22. CONCLUSION
• Cloud computing is a better way to run your business. Instead of
running your apps yourself, they run on a shared data center. When
you use any app that runs in the cloud, you just log in, customize
it, and start using it. That's the power of cloud computing.
• Cloud computing increases profitability by improving resource
utilization. Costs are driven down by delivering appropriate resources
only for the time those resources are needed. ? Cloud computing has
enabled teams and organizations to streamline lengthy procurement
processes.
• Finally, cloud apps don't eat up your valuable IT resources, so your
CFO will love it. This lets you focus on deploying more apps, new
projects, and innovation
