• It free and the user can modify the code
• I am not advocating you use these products;
but you should be aware of them

5. Cloud computing
http://en.wikipedia.org/wiki/Cloud computing
Cloud computing is the delivery of computing as a service
rather than a product, whereby shared resources, software,
and information are provided to computers and other
devices as a utility (like the electricity grid) over a network
(typically the Internet).
Cloud computing entrusts, typically centralized, services with
your data, software, and computation on a published
application programming interface (API) over a network. It
has a lot of overlap with software as a service (SaaS).

Software as a service (SaaS)
Web-based applications (Google, Facebook)
Platform as a service (PaaS)
Software environments (Google App Engine,
Microsoft Windows Azure)
Infrastructure as a service (IaaS)
Computing environments (Amazon Web Services,
Rackspace Cloud)
This presentation will focus on IaaS

Hybrid
Combination of public and private models
9. PUBLIC CLOUD
• CuA public cloud, or external cloud, is the most common form of
cloud computing, in which services are made available to the
general public in a pay-as-you-go manner.
• stomers – individual users or enterprises – access these services
over the internet from a third-party provider who may share
computing resources with many customers.
• The public cloud model is widely accepted and adopted by many
enterprises because the leading public cloud vendors as Amazon,
Microsoft and Google, have equipped their infrastructure with a
vast amount of data centers, enabling users to freely scale and
shrink their rented resources with low cost and little management
burden.

• There are many public cloud service providers in place today,
offering services ranging from infrastructure-as-as-service, to
development-platform-as-a-service, to special purpose
application-as-a-services.
• Examples of top Public Cloud Deployment model Providers:
• Amazon EC2
• Google App Engine
• Microsoft Azure
• IBM Cloud

12. PRIVATE CLOUD
• A Private Cloud, or internal cloud, is used when the cloud
infrastructure, proprietary network or data center, is operated
solely for a business or organization, and serves customers within
the business fire-wall.
• Most of the private clouds are large company or government
departments who prefer to keep their data in a more controlled
and secure environment.

14. HYBRID CLOUD
• A composition of the two types (private and public) is called a
Hybrid Cloud, where a private cloud is able to maintain high services
availability by scaling up their system with externally provisioned
resources from a public cloud when there are rapid workload
fluctuations or hardware failures.
• In this model users typically outsource non business- critical
information and processing to the public cloud, while keeping
business-critical services and data in their control.
