Sustainability and IT
Accelerating business innovation;

Not our problem, right?
•Average utilisation of
equipment in the Data Centre is
10-15%
–Worse with redundancy
•Powering processors consumes
about 6-10% of the Data Centre
budget.
–The rest goes on UPS;
Lighting; Cooling; AC:DC:AC
•Total carbon emissions is
estimated at around 2-3% and
rising
•And energy costs will continue
to rise too!

Standard Building Blocks
Accelerating business innovation;
a Technology Strategy Board programme
Cloud is a business model; Grid is an access model
Both are implemented using similar (or even the same)
technology components, which can be thought of as
building blocks
These building blocks are used to build Clouds or Grids –
depends on what you need
So if a standard exists for a particular Grid building
block, it might be applicable to building Clouds

Is Cloud Disruptive?
Accelerating business innovation;
a Technology Strategy Board programme
Definitely! But not a technology disruption. It’s a
disruptive business model.
Cloud is characterized by services made available ondemand, and payment for these services based on
actual usage.
Some say Grids evolve to Clouds, others say Clouds are
completely different from Grids
Either way we have learned a lot about distributed
computing thus far and this should help …

Are We Done?
Accelerating business innovation;
a Technology Strategy Board programme
While the referenced set of specifications provide some
significant building blocks, others still need
definition
Term languages for describing Cloud resources and QoS
constraints
Extend Basic Execution Services state model to
accurately describe VM instance lifecycle
New information attributes for describing Cloud services
and applications
And the list goes on….

What is …..?
Accelerating business innovation;
a Technology Strategy Board programme
… a Service (S) ?
… Service Orientation
(SO) ?
A repeatable
business task – e.g.,
check customer credit;
open new account
A way of integrating your
business as linked
services
and the outcomes that
they bring
… Service Oriented
Architecture (SOA) ?
… a composite
application?
An IT architectural
style that supports
service orientation
A set of related &
integrated services that
support a business
process built on an SOA

• Extraction of business scenarios and processes
from application landscape
• Clear focus on defined services, which are
reusable through an assebly of services
• Internal and external users get better access to
data in different systems

Dynamic reconfiguration of
infrastructure
License/Asset Management
Virtual server sprawl
Reliance on automated tools
New types of users: web hackers;
social networkers
New types of problems: mashups; service rogues; service storms
Resolving faults in distributed
environments
IT will be the last to find out …

Summary
Accelerating business innovation;
a Technology Strategy Board programme
Cloud-based/Utility computing is coming of age
It lies at the heart of the most innovative web services
delivered today
It provides cheap and easy access to infrastructure
It provides a platform which is ideal for service delivery
Software distribution and use models are changing
Legacy hardware and applications present some
obstacles
Energy concerns represent a threat and an opportunity
The IT function is poised for radical change!

Bill Gates, Microsoft, at TechEd, June 3rd 2008
Accelerating business innovation;

“We're taking everything we do at the server level,
and saying that we will have a service that mirrors that exactly.
The simplest one of those is to say, okay, I can run Exchange
on premise, or I can connect up to it as a service. But even at
the BizTalk level, we'll have BizTalk Services. For SQL, we'll
have SQL Server Data Services, and so you can connect up,
build the database. It will be hosted in our cloud with the big,
big data center, and geo-distributed automatically. This is kind
of fascinating because it's getting us to think about data
centers at a scale that never existed before. Literally today we
have, in our data center, many hundreds of thousands of
servers, and in the future we'll have many millions of those
servers.”
