OVERVIEW
INTRODUCTION TO CLOUD COMPUTING
- The term cloud computing is quickly becoming ubiquitous
- Cloud computing is a new pattern of IT consumption but it is proving
elusive to define
- (Untitled sub-section)
- Cloud computing: an IT consumption pattern based on the delivery of
commoditized resources as a service
- IT commoditization has occurred through the history of computing
- Cloud computing may resemble the mainframe era, but it is a fundamentally
different phenomenon
- Electricity provides the most powerful analogy with cloud computing
- The cloud computing taxonomy
- Software-Platform-Infrastructure (SPI) model offers the basic cloud
computing classification
- Further refinement of the SPI model should not rely on the proliferation
of ' as a Service' neologisms
- Detailed taxonomy schemas focus on segmenting the infrastructure layer
- The fabric/instance spectrum captures variations in the granularity of
computing services provision
- Do private clouds exist?
BENEFITS OF CLOUD COMPUTING
- The benefits of cloud computing are the benefits of services over products
- Cloud computing allows enterprises to focus on their core business
processes
- Cloud computing closes the gap between IT capacity and IT demand
- Variable costs and usage-based models are the principal benefits of cloud
computing pricing
INHIBITORS TO CLOUD COMPUTING ADOPTION
- Trust and migration to an unfamiliar model are the primary inhibitors to
cloud computing
- The substitution of products with external services renders the issue of
trust extremely acute
- Cloud service adoption and management challenges are currently potent
inhibitors
- (Untitled sub-section)
- Conclusion: benefits and inhibitors of the cloud computing model
COMPETITIVE LANDSCAPE
- The roll-out of cloud infrastructures is an opportunity for commodity
hardware vendors
- Migration into the cloud will boost thin clients, netbooks and handhelds
- Cloud infrastructure services
- Online retailer Amazon.com has emerged as the early leader in
infrastructure provision
- GoGrid leads the wave of hosting providers offering instance-based cloud
computing infrastructure
- Others could offer cloud infrastructure services, but may prefer to
compete in software or platform layers
- Infrastructure management platforms have emerged as the critical part of
the cloud infrastructure stack
- Cloud platform competitive landscape is particularly vibrant
- Proprietary development platforms backed by SaaS vendors are proving
popular with ISVs and users
- Platforms supporting generic development frameworks may lend more control
to developers
- A long tail of standalone platforms relies on intuitive proprietary
development and execution environments
- SaaS vendors now feature in virtually every segment of the enterprise
application market
DATAMONITOR OPINION
- Those that manage to harness the cloud computing model stand to benefit
- Cloud computing is here to stay, albeit not as the sole model of IT
consumption
- The Global Recession will accelerate the adoption of cloud computing
- Unchecked proliferation and inadequate management of cloud computing
services can fuel the backlash
- Successful vendors will capitalize on short-term opportunities and prepare
for long-term implications
RECOMMENDATIONS
- Action points for enterprise technology vendors
- Action points for enterprise IT decision makers

approximate the scale of the internet
- Figure: Adopting a service-based IT consumption strategy allows greater
focus on strategic issues
