Gartner: Cloud computing is “the most
hyped subject in IT today”!!

30
MINUTES

TO



Cut through some of the hype


Provide a non
-
IT
-
expert guide to “Cloud”


Explain what we’ve been doing at Brock


Outline the costs and the benefits


So that you…


Understand enough about cloud technology to
hold your own in discussions with the techies


Can relate this over
-
hyped technology to your
business priorities

INVESTMENTS

dated equipment!


Variable asset utilization


Most servers run at 5
-
20% of processing capacity


Even virtualised servers get nowhere near 100%


Data
redundancy and
security


Computing/networking reliability & redundancy


Backup and DR (disaster recovery)


Power
and cooling
efficiency


Datacentres: 1 watt to the server, 1.5 watts in overhead!


P
ersonnel costs


Recruitment, retention, training

Or maybe we could spend more
money at the frontline of teaching
and learning?

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”.



(US National Institute of Standards and Technology)

Blah, blah, blah,

CAMPUS

IT?


Yes. Some.


PCs, printers, networking, high
-
end media


But different ownership models; different support
models; utility computing; thin clients


A data centre


But smaller; bridge between the college and the
cloud; more proactive monitoring/self
-
healing; shared
services


An IT Support structure


But smaller; more contract and supplier relationship
management etc… skills gaps?

What are the organisational
development implications?

Our data is somewhere “out there”?


Security; public or private cloud? is the door locked?


Where in the world is our stuff?


Legal jurisdictions? regulatory compliance; data

SLAs


Service/support; uptime guarantees (with financial
penalties?); technical support; time zones?


Partners


Trust; reliability


Single points of failure?


JANET connection: capacity/cost; redundancy?

Lots of due diligence needed!

fewer fixed

Capex

enhanced
cashflow


Quality improvement


Getting more
service/capacity;
providing
better
services to our customers


Innovation and agility


The world changes; IT changes; opportunities change;
keeping up with the next big thing!


Focussing
on what we’re good
at!


Keeping what adds value, outsourcing what doesn’t,
adding more value by buying
-
in just the services we
need



If we join the ride down from the
“peak of inflated expectations”, we
might reach that “plateau of
productivity” in 2 years!!

Nick Carr was right!


Most computing is now
a “utility”


we can’t
live without IT, but “IT
doesn’t matter”


Your IT infrastructure
doesn’t differentiate
you from me!


So don’t spend any
more £ (or $) than
absolutely necessary on
IT!
