A public cloud (also called External Cloud)is one
based on the standard cloud computing model, in
which a service provider makes resources, such as
applications and storage, available to the
general public over the Internet. Public cloud
services may be free or offered on a
pay-per-usage model.
11

• The main benefits of using a public cloud service
  are
• Easy and inexpensive set-up because hardware,
  application and bandwidth costs are covered by
  the provider.
• Scalability to meet needs.
• No wasted resources because you pay for what you
  use.

12
Private cloud (also called internal cloud or
corporate cloud) is a marketing term for a
proprietary computing architecture that provides
hosted services to a limited number of people
behind a firewall. ?Advances in virtualization
and distributed computing have allowed corporate
network and datacenter administrators to
effectively become service providers that meet
the needs of their "customers" within the
corporation.
13
A hybrid cloud is a composition of at least
one private cloud and at least one public cloud.
A hybrid cloud is typically offered in one of two
ways a vendor has a private cloud and forms a
partnership with a public cloud provider, or a
public cloud provider forms a partnership with a
vendor that provides private cloud platforms
14
Community clouds are a deployment pattern
suggested by NIST, where semi-private clouds will
be formed to meet the needs of a set of related
stakeholders or constituents that have common
requirements or interests. ?Communities of
Interest (COI) constructs typical of the federal
government may be enabled by community clouds to
augment their wiki-centric collaboration
processes with cloud enabled capabilities as well.
15
The SOA RA as being standardized by The Open
Group, applies to Cloud architectures and is the
underlying architecture for the IBM CCRA.

• Cloud Service Models
• Cloud Computing can be broadly classified into
  three aaS, i.e., three layers of Cloud Stack,
  also known as Cloud Service Models or SPI Service
  Model
• Infrastructure-as-a-Service (IaaS)
• Platform-as-a-Service (PaaS)
• Software-as-a-Service (SaaS)
