Agenda
What is the cloud?
How did we get here?
Some sample Cloud applications
State of the Cloud
Cloud drives for your computer
SaaS and PaaS
Land mines and Gold mines
![Page 3: Cloud Computing Overview](https://reader031.vdocuments.us/reader031/viewer/2022032421/55a647b81a28ab492e8b4782/html5/thumbnails/3.jpg)
GOAL FOR THE DAY
Not that you walk out with all the solutions (you
should get some…), but that you walk out with a
framework with which to judge future Cloud
offerings and technologies.

CENTRALIZED POWER ADVANTAGES
Pay for power as you use it
Share the cost of building the infrastructure
Quick and easy to get power to your new
building
Someone else worries about hiring electrical
engineers to keep turbines going
Flexibility for when you grow or have temporary
needs

DISADVANTAGES OF CENTRAL POWER
When it’s hot in town, everyone wants
more
Outages can affect a lot of people
Price doesn’t benefit from a
competitive market

CENTRALIZED MONEY STORAGE
Better protection that you can provide
alone
Marketplace provide competitive rates
and services
Insurance provided by the bank
When they fail or get robbed, a lot of
people lose money,
but insurance can help

“Unfortunately for IT, if this attitude lasts, the IT department will not”
“The emergence of the cloud has accelerated the growing rift between IT departments and the senior executives”
“Where companies have begun using cloud services, it appears that they will continue to do so”
“Organizations that use the cloud can focus on their core competencies instead of waiting on IT and dealing with restrictions”

The Key Point
• Traditional model of IT: purchase a capital
investment and maintain and service over
time until you have to replace it
• Cloud model of IT: Spending from
operational expense budget for a service
when you need it

CLOUD DRIVE NOTES
Your data away from your computer (work, business, laptop, home)
SugarSync will make multiple computer directories the same
You’ll need to buy special software to backup your computer to the Cloud
Photos typically get special treatment
Skydrive shrinks them
Skydrive and DropBox create galleries
Sharing might include editing
Skydrive and Google can edit in the browser
Google Docs format is special
Doesn’t count toward your storage quota
Multiple people can edit at the same time
Seeing your data on other devices
SugarSync and DropBox support everything including Blackberry (DropBox: Linux, too!)
Google works on iPhone and 3rd parties have stepped up for Android apps for SkyDrive
Searching is not uniform across the platforms
DropBox indexes filesnames only
SkyDrive indexes the words inside Microsoft files (Word, Excel, PowerPoint, etc.)
Google indexes everything!
SugarSync doesn’t search!

Tricky Stuff for ITO Integration between platforms
O Credentialing in general and Single-sign-on in
particular
O Predicting and maintaining performance and
bandwidth needs
O Regulatory management and control
O Does our software work there? Licensed properly?
O From managing staff to managing vendors
O Reporting and KPIs for Executives
O Reduced staff
![Page 151: Cloud Computing Overview](https://reader031.vdocuments.us/reader031/viewer/2022032421/55a647b81a28ab492e8b4782/html5/thumbnails/151.jpg)
Benefits for the Business
O Flexibility is better than forecasting
O It’s good to be able to capture the revenue from a peak
O Utility costing “plains” are preferred to “mountains and valleys” of capital costing
O Agility in creation and delivery of new digital products and services
O Probable cost reduction
O Probable over-all technology improvements

Tricky Stuff for the Business
O Change is hard – migrations and cut-overs and outages and training and new (important) partners can all present challenges
O Multi-year contracts are sometimes hard to commit to
O Difficult to properly weigh risk profiles and scenarios
O Another batch of layers between the business and IT

A definition:
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.

What it Boils Down to…
Better Control
• Your gear – your responsibility
• You’re in charge of your own
response to problems
• You know the capabilities of
your staff and can direct them
• You just have to manage
YOUR threats, not everyone’s
Advanced Functionality
• Quick to market
• Quick to upgrade or
downgrade as needed
• Service-based metered pricing
• 24/7
• Newer technology faster

Risk Mitigation• Cloud providers want predictable, multi-
year, enterprise-wide agreements
• Customers want PAYG add (and subtract)
services as needed
• Neither party can assume all of the risko Vendors will go out of business
o Customers will never put mission critical in the Cloud
![Page 157: Cloud Computing Overview](https://reader031.vdocuments.us/reader031/viewer/2022032421/55a647b81a28ab492e8b4782/html5/thumbnails/157.jpg)
Service Level Agreements• Is there an up-time guarantee and what are the
penalties? Push for more than fee returns.o Consider Business Interruption Insurance
• Understand where to go for support or to report a
problem and what is the response time?
• Do they have a DR plan in place?
• Are your regulatory needs met (PCI, Cobit, etc.)?
• Make sure you understand (or eliminate)
“suspension of service” situations
• Verify no data sharing with your private
information.

STANDARD PATH TO THE CLOUD
• experiment with unimportant service or software and with
multiple providers
• when something gets old, rent a cloud server
• use for development and test, then deploy to owned gear
• get comfortable and continue to migrate
• experiment and migrate to PaaS/IaaS and SaaS
• deploy new services on the cloud
• consider reductions in technology support staff
![Page 159: Cloud Computing Overview](https://reader031.vdocuments.us/reader031/viewer/2022032421/55a647b81a28ab492e8b4782/html5/thumbnails/159.jpg)
“STARTUP” PATH TO THE CLOUD
• Find SaaS providers for office applications
• Develop and host web presence through partners
• Hire technical people in year 5 to manage partners

RecommendationsNothing longer than a 2-3 year
commitment if you have to commit
You have to do your homework before you commit
Integration with existing applications
Network surveys to determine bandwidth needs
Understand the SLA completely
If you have an IT department, they need to be on-board (even excited) in order for this to work
![Page 161: Cloud Computing Overview](https://reader031.vdocuments.us/reader031/viewer/2022032421/55a647b81a28ab492e8b4782/html5/thumbnails/161.jpg)
Recommendations (con’t)
Understand and practice your exit
strategy (just another part of your BCP)
If you have existing good relationships
with hardware vendors, start with them
