Preface
• List the four major cloud deployment types
• Describe the features of private, public, hybrid, and community
clouds
• List some additional cloud deployment types
• Select the most appropriate deployment model based on a set of
business and technical requirements
Agenda
• Cloud deployment models - public, private, hybrid, community clouds
• Selection criteria for cloud deployment types
Cloud deployment models
• There are 4 cloud deployment model that will be covered during this
chapter
• Public Cloud
• Private Cloud
• Community Cloud
• Hybrid Cloud
Gartner Definition of Public Cloud computing
• Gartner defines public cloud computing as a style of computing
where scalable and elastic IT-enabled capabilities are provided as a
service to external customers using Internet technologies—i.e., public
cloud computing uses cloud computing technologies to support
customers that are external to the provider’s organization.
• Using public cloud services generates the types of economies of scale
and sharing of resources that can reduce costs and increase choices
of technologies.
Public Cloud
• A public cloud is a publicly accessible cloud environment owned by a
third-party cloud provider. The IT resources on public clouds are
usually provisioned via the previously described cloud delivery
models and are generally offered to cloud consumers at a cost or are
commercialized via other avenues (such as advertisement).
• The cloud provider is responsible for the creation and on-going
maintenance of the public cloud and its IT resources. Many of the
scenarios and architectures explored in upcoming chapters involve
public clouds and the relationship between the providers and
consumers of IT resources via public clouds.
Gartner definition of Private Cloud computing
Private cloud computing is a form of cloud computing that is used by
only one organization, or that ensures that an organization is
completely isolated from others.
Private Cloud Computing
• A private cloud is owned by a single organization. Private clouds
enable an organization to use cloud computing technology as a
means of centralizing access to IT resources by different parts,
locations, or departments of the organization.
• The use of a private cloud can change how organizational and trust
boundaries are defined and applied. The actual administration of a
private cloud environment may be carried out by internal or
outsourced staff.
Hybrid Cloud Computing
• A hybrid cloud is a cloud environment comprised of two or more
different cloud deployment models. For example, a cloud consumer
may choose to deploy cloud services processing sensitive data to a
private cloud and other, less sensitive cloud services to a public cloud.
• Typical challenges:
• Management
• Workload Balancing,
• Brokerage / Integration
• Portability
Hybrid Cloud Use Cases (examples)
System of records vs system of engagement
SoE: EXAMPLES:
Hong Kong department Stores
A chain of Hong Kong department stores
used its Web-based system of engagement
to capture the near-real-time activity of
each Web visitor and achieved a 250
percent higher conversion rate with
customer-generated product reviews.
North American airline
A Canadian airline carrier increased
customer satisfaction and streamlined
booking operations by offering a mobile
self-service solution that increased mobile
check-ins by 13.5 percent. These systems
of engagement increased mobile flight
pass bookings and reduced the cost of
check-in cost by 80% compared to
traditional counter check-in process

A virtual private cloud (VPC) is dedicated to a single user within a public cloud.
The virtual private cloud extends the customer network into the cloud provider’s
“space”, making the additional resources available on demand.
For IBM Internal Use Only
Private cloud Public Cloud
Employee information or other sensitive data typically
restricted to the enterprise
Test systems and environments
Workloads composed of multiple, co-dependent
services
Pre-production systems and environments
Workloads requiring customization Mature packaged offerings, like e-mail and
collaboration
Workloads based on third-party software that does
not have a virtualization or cloud-aware licensing
strategy
Storage solutions (including storage as a service)
High throughput online transaction processing Backup solutions (including backup and restore as a
service)
Batch processing jobs with limited security
requirements
Data-intensive workloads if the provider has a cloud
storage offering linked to the cloud compute
Workload types – cloud suitability (public vs. private)
Community Cloud
• A community cloud is similar to a public cloud except that its access is
limited to a specific community of cloud consumers. The community
cloud may be jointly owned by the community members or by a thirdparty
cloud provider that provisions a public cloud with limited
access. The member cloud consumers of the community typically
share the responsibility for defining and evolving the community
cloud
