Cloud Computing market size has significant
expectations of growth and revenue
 By 2012, customer spending on IT cloud services will
grow almost threefold, to $42 billion – IDC
 Gartner says the size of the 2008 cloud computing
market stood at $46 billion and will jump to $150
billion by 2013 (includes AdWords)
 Cloud computing markets at $36 billion 2008 are
expected to reach $160.2 billion by 2015 –

Most Fortune 500 companies are expected to
implement internal clouds of some sort

Analyst projections are consistent due to significant
perceived opportunities by venture capitalists

Agenda
Why Cloud Computing

Working Definitions of Cloud Computing points
to improved business agility benefits
Cloud computing is a model for enabling convenient, on-demand network
access to a shared pool of configurable computing resources (e.g.,
networks, servers, storage, applications, and services) that can be rapidly
provisioned and released with minimal management effort or service
provider interaction
A standardized IT capability (services,
software, or infrastructure) delivered
via Internet technologies in a pay-per-
use, self-service way
A style of computing in which
massively scalable IT-enabled
capabilities are delivered “as a
service” to multiple customers using
Internet technologies
This cloud model promotes availability and is composed
of five essential characteristics, three delivery models,
7
and four deployment models

Cloud solutions need to meet some key
characteristics
 On-demand self-service
 Ubiquitous
network access
 Location
independent
resource pooling
 Rapid elasticity
 Measured service
8
 Shared
infrastructure
 Advanced
Virtualization
 Multi-tenancy
 Lower time to
value
Inability to meet these characteristics will reduce the
benefits harnessed from cloud computing

Cloud technology adoption can be categorized
under three major delivery models
 Business Process as a Service (BPaaS)
 Software as a Service (SaaS)
 Platform as a Service (PaaS)
 Infrastructure as a Service (IaaS)
 Other Delivery Models
9
– Database as a Service
– Government as a Service
– STorage as a Service
– Information as a Service
– Identity as a Service
– E-mail as a Service
– ERP as a Service
– TAX as a Service
– DEsktop as a Service
To be considered “cloud” they must be deployed on top
of cloud infrastructure that has the key characteristics

Each delivery model has unique characteristics
with leading providers
10
Characteristics *-As-A-Service
Examples
Activities delivered remotely
combining multiple resources bound
together
Business
Process
PayPal, Fedex, ADP
Application available on demand to
end user used by software
consumers
Software or
Application
Salesforce, Webex,
Workday(HR), Google Apps
Storage, compute and other
services to simplify application
development, especially of web
applications mainly used by
application developers
Platform Azure, Google AppEngine,
Force.co.uk
Compute power, storage and
networking infrastructure over the
internet, provided as a virtual
machine image used by developers
Infrastructure Amazon, GoGrid, FlexiScale,
RackSpace

Cloud technology adoption falls under different
deployment models
 Private cloud
–enterprise owned or leased
 Community cloud
–shared infrastructure for specific community
 Public cloud
–Sold to the public, mega-scale infrastructure
 Hybrid cloud
–composition of two or more clouds
11
Two types: internal and external

Cloud computing implementation has some
common characteristics
 Massive scale
 Virtualization
 Free software
 Autonomic computing
 Homogeneity
 Geographically distributed systems
 Advanced security technologies
 Service oriented software
12
Some of these characteristics will be limited when
implementing private clouds

The taxonomy for cloud computing depicts how
various components need to work together
13

The relationships between standards and taxonomies
can be used as a starting point to lay out a roadmap
14
Building a
small, low-risk
and limited
term cloud
implementation
within an
enterprise can
provide the
foundation to
exploit
additional
benefits as
cloud
technology
matures
