Two seemingly contradictory statements…
Cloud Computing is MASSIVELY overhyped
Cloud Computingwill forever change
the computing world
today future (not so distant…)
… both are true, the question is “when”?
Cloud: Hype & Confusion
Customer Demand• Real success stories have
emerged from the internet… − Google, Amazon, eBay, Yahoo,
Microsoft, etc
• Delivering astonishing results … − Robust solutions, at enormous
scale, on very low cost infrastructure
• The pain points around utilization, cost, and flexibility are shared by all customers…
− Extremely high demand for solutions to these problems
− Aggravated by current economic situation
Marketing Hype• Dell: Attempted to trademark “cloud
computing” – denied!• IBM: Suddenly everything is “cloud
computing” new and old• Others: Every vendor with any
product that abstracts anything…
Sources of Confusion• New/emerging technology &
terminology
− Web2.0, Mash-Ups, Ruby, Rails, AJAX, and many many more…
− IaaS, PaaS, SaaS, STaaS…• Confusion around Internal vs.
External Clouds
“A Tale of Two Clouds….”
Distinguishing between two distinct phenomena …
Enterprise IT Transformation (Internal Clouds)
and
[True] Cloud Computing
Enterprise/Large SMBs
External Service Providers
Primary Business
Varies: Auto, Aero, Other Manufacturing, Pharmaceutical, Health Care, Retail, Entertainment, Communications, etc.
Examples: GM, Boeing, Coach, Glaxo, Kaiser, Walmart, …
Providing external services to consumer, SMB, or enterprise customers (for profit) over the public internet.
Examples: Google, Amazon, eBay, SalesForce, Yahoo, Facebook
Role ofIT
Business IT; basic IT functions to enable business; HR, Business process, Decision support, collaboration, etc.IT is a cost center
same
Business IT: Service providers have a business IT function similar to business IT for other enterprises.IT is a cost center
External Service IT: Internet facing IT infrastructure optimized for massive scale at a low costIT is core to the customers business
Traditional Enterprise
HPC Infrastructure; some enterprises have HPC infrastructure to do modeling and simulation for engineering, research, financial analytics, etc.also a cost center
Unique to Service Providers

Enterprise IT Transformation• Moving from dedicated resources to shared resource
pools• Enabled by virtualization, automation and embracing
service centric IT• Evolutionary – has been going on for years• Delivers improved cost, greater business agility, and
enables IT to survive and thrive in a hybrid world

Enterprise and cloud…
• Security concerns− Especially for regulated industries
• Integration− Especially for Business Processing
applications
• Quality of Service and Continuity SLAs
− Especially for mission/business critical applications
− Fundamental issue for IaaS
• Parallelization
• Transactional semantics
• Data semantics
• Program correctness
• Testing/scaling

Barriers to using cloud servicesChallenges in creating cloud services
WorkloadCategories
Creation Barriers
Adoption Barriers
Timeframe
Collaboration Low; services exist Low; being adopted Now/Significant adoption soon
Web Infrastructure Low; possible Low Early adoption soon
IT Infrastructure Low-medium; some services today
Medium to low Early adoption soon
Decision Support Medium High: Security, Integration and SLAs
3-5 years
Business Processing High High: Security, Integration and SLAs
Last to move; 5+ years
Conclusions
The future of Enterprise IT is a hybrid
environment…services sourced
internally, outsourced, or from cloud service
providers
Cloud computing is revolutionary and will ultimately change the
world…but not overnight
Enterprise IT transformation is an evolutionary process
that has been happening for
years…
There are significant barriers for creating and adopting cloud
services for enterprises…

Adaptive Infrastructure
Cloud properties start out as multi-tenant
from a user perspective but single
tenant from an application perspective
Cloud properties become multi-tenant from an application perspective when they open up and become platforms
Multi-tenancy: More than one [user, application, or both]

Virtualization
Often ad-hoc / non-uniformLimited scale shared storage:
SAN for the Database tier; NAS growing in popularity
Massive scale shared storage:High-performance tier; caching layer to
hide latency; object semantics; separation of meta data
