3. What is Cloud computing
Cloud computing means that infrastructure, applications, and
business processes can be delivered to you as a service, over the
Internet (or your own network).
The physical cloud resources may reside in a number of
locations, the details of which are not typically known to the
service’s users.

4. Why cloud computing
Cloud computing provides a way to increase capacity or add
capabilities on the fly without investing in new infrastructure,
training new personnel, or licensing new software.
Cloud computing is cost smart it is a pay-per-use service that, in
real time over the Internet, extends IT's existing capabilities.

5. Benefits of Cloud Computing
Ease of Use
Scalability
Risk free
Reliability
Cost smart

6. Ease of use
Deploy infrastructure easily
No cabling, screwdrivers, racking, unboxing, buying hardware or /and
software
Middle of the night
Do it yourself remotely from anywhere anytime

7. Scalability
Control your infrastructure
Scale up/Down
Upgrade as you grow
Instant

8. Risk free
Nothing to buy/ maintain / fix .
Cancel immediately
Change instantly, even operating systems
No need to worry about hardware failures

9. Reliability
Based on enterprise grade hardware.
Design to be failure free :
Automatically spin up replacements
Use multiple clouds

10. Cost
You pay only for what you use.
You are billed on the amount of resources
consumed.

11. Anatomy of the Cloud

12. Layers of the Cloud
•The client layer acts as the user interface to which cloud computing
services are delivered. Client layer hardware can include personal
Client computers, web browsers, mobile devices, and even telephones.
•Cloud application services or "Software as a Service (SaaS)" deliver software as
a service over the Internet, eliminating the need to install and run the
application on the customer's own computers and simplifying maintenance and
Application support.
•Often referred to as the infrastructure layer, the virtualization layer is the result
The Virtualization of various operating systems being installed as virtual machines
Layer
•The servers layer consists of computer hardware and/or computer software
products that are specifically designed for the delivery of cloud services,
including multi-core processors, cloud-specific operating systems and combined
The Hardware Layer offerings.

13. Deployment Models
Public Model Community Model private Hybrid Model
When the cloud shares infrastructure When the cloud is a composition of two or
computing infrastructure between several computing infrastructure more clouds (private,
is located beyond the organizations from a is located within the community, or public)
premises of the specific community with premises of the that remain unique
enterprise, and is common concerns enterprise, and is entities but are bound
accessed through a (security, compliance, accessed through a together, offering the
network which is either jurisdiction, etc.), whether secure private network benefits of multiple
public or private in nature managed internally or by then this type of model is deployment models.
then such a model is a third-party and hosted termed as a private cloud.
called as a Public Cloud. internally or externally.
