3. Cloud Computing
Binesh Kr. Singh (11H51F0006)
• Cloud computing is a way of computing, via the
Internet, that broadly shares computer resources
instead of using software or storage on a local
computer.
• A technical definition is "a computing capability
that provides an abstraction between the
computing resource and its underlying technical
architecture
(e.g., servers, storage, networks), enabling
convenient, on-demand network access to a
shared pool of configurable computing resources
that can be rapidly provisioned and released with
minimal management effort or service provider
interaction."

4. Cloud Computing
Binesh Kr. Singh (11H51F0006)
• Cloud computing is a phrase used to describe a
variety of computing concepts that involve a large
number of computers connected through a realtime communication network such as the Internet.
• In science, cloud computing is a synonym for
distributed computing over a network, and means
the ability to run a program or application on
many connected computers at the same time.
• The popularity of the term can be attributed to its
use in marketing to sell hosted services in the
sense of application service provisioning that run
client server software on a remote location.

5. Examples of Cloud Computing Storage

6. Cloud Flavors?
Binesh Kr. Singh (11H51F0006)
•
•
•
•
SaaS – Software as a Service
IaaS – Infrastructure as a Service
PaaS – Platform as a Service
DaaS – Desktop as a Service

7. What is Software as a Service? (SaaS)
Binesh Kr. Singh (11H51F0006)
• SaaS is a software delivery methodology
that provides licensed multi-tenant access
to software and its functions remotely as a
Web-based service.
– Usually billed based on usage
– Usually multi tenant environment
– Highly scalable architecture

8. SaaS Examples
Binesh Kr. Singh (11H51F0006)

9. Infrastructure as a Service (IaaS)
Binesh Kr. Singh (11H51F0006)
• IaaS is the delivery of technology
infrastructure as an on demand scalable
service
– Usually billed based on usage
– Usually multi tenant virtualized
environment
– Can be coupled with Managed Services for
OS and application support

10. IaaS Examples
Binesh Kr. Singh (11H51F0006)

11. Platform as a Service (PaaS)
Binesh Kr. Singh (11H51F0006)
• PaaS provides all of the facilities required
to support the complete life cycle of
building and delivering web applications
and services entirely from the Internet.
– Typically applications must be developed
with a particular platform in mind
– Multi tenant environments
– Highly scalable multi tier architecture

12. PaaS Examples

13. Deployment Models
Binesh Kr. Singh (11H51F0006)
Public cloud
• Public cloud (off-site and remote) describes cloud computing where resources are
dynamically provisioned on an on-demand, self-service basis over the Internet, via web
applications/web services, open API, from a third-party provider who bills on a utility
computing basis.
Private cloud
• A private cloud environment is often the first step for a corporation prior to adopting a
public cloud initiative. Corporations have discovered the benefits of consolidating shared
services on virtualized hardware deployed from a primary datacenter to serve local and
remote users.
Hybrid cloud
• A hybrid cloud environment consists of some portion of computing resources on-site (on
premise) and off-site (public cloud). By integrating public cloud services, users can leverage
cloud solutions for specific functions that are too costly to maintain on-premise such as
virtual server disaster recovery, backups and test/development environments.
Community cloud
• A community cloud is formed when several organizations with similar requirements share
common infrastructure. Costs are spread over fewer users than a public cloud but more
than a single tenant.

14. Advantages of Cloud Computing
Binesh Kr. Singh (11H51F0006)
• Achieve economies of scale – increase volume output
or productivity with fewer people. Your cost per unit,
project or product plummets.
• Reduce spending on technology infrastructure.
Maintain easy access to your information with minimal
upfront spending. Pay as you go (weekly, quarterly or
yearly), based on demand.
• Globalize your workforce on the cheap. People
worldwide can access the cloud, provided they have an
Internet connection.
• Streamline processes. Get more work done in less
time with less people.

15. Advantages of Cloud Computing
Binesh Kr. Singh (11H51F0006)
• Reduce capital costs. There’s no need to spend big money on
hardware, software or licensing fees.
• Improve accessibility. You have access
anytime, anywhere, making your life so much easier!
• Monitor projects more effectively. Stay within budget and
ahead of completion cycle times.
• Less personnel training is needed. It takes fewer people to do
more work on a cloud, with a minimal learning curve on
hardware and software issues.
• Minimize licensing new software. Stretch and grow without
the need to buy expensive software licenses or programs.
• Improve flexibility. You can change direction without serious
“people” or “financial” issues at stake.

16. Dis-Advantages of Cloud Computing
Binesh Kr. Singh (11H51F0006)
•
•
•
•
•
Security and privacy in the Cloud
Dependency and vendor lock-in
Technical Difficulties and Downtime
Limited control and flexibility
Increased Vulnerability

17. Conclusion
Binesh Kr. Singh (11H51F0006)
• Cloud Computing is outpacing the IT industry
• Real business value can be realized by customers of all sizes
• Cloud solutions are simple to acquire, don’t require long term
contracts and are easier to scale up and down as needed
• Proper planning and migration services are needed to ensure
a successful implementation
• Public and Private Clouds can be deployed together to
leverage the best of both
• Third party monitoring services ensure customer are getting
the most out of their cloud environment
• Security Compliance and Monitoring is achievable with careful
planning and analysis
