WHY MOVE TO
THE CLOUD?
Eric Nelson
Slide 6
CUSTOMERS ARE LOOKING FOR
TANGIBLE BENEFITS & REAL VALUE
Slide 7
BENEFITS
Agility
Focus
Efficiency
• My IT infrastructure must
respond quickly to
business needs
• I want to focus on
delivering value – not on
managing technology
infrastructure
• I’m seeking a cost effective
solution to manage my IT
resources
Simplicity
Partnering
• I need to better leverage
my existing infrastructure
and the staff I already have
• My partners need to share
my vision and help enable
it
Slide 8
CLOUD DELIVERS VALUE
Reduced IT Complexity
Lower TCO
• Releases valuable resources to
focus on high value areas
• Reduce infrastructure and
operational costs
• Early ROI for the consumer
Automated Management
Comprehensive SLA
• Automated service management
means automatic upgrades and
no more patches
• Platform as a service provided at
global scale with a dependable
service level agreement
Slide 9
BUT BEFORE WE CONTINUE…
Are these benefits delivered by
cloud platforms?
Or
By products delivered as SaaS?
Slide 10
CAST YOUR MIND BACK TO 2007…
SOFTWARE AS A SERVICE
From http://www.slideshare.net/SmartManQ8/saas-1597107
Slide 11
THE RIGHT QUESTIONS TO ASK
“Why move to the cloud” is better phrased as two questions:
Why move from on-premise deployment
to SaaS?
and
Which technology should I write my SaaS
on top of?

MAKING THE MOVE TO THE CLOUD
Slide 21
EVALUATING YOUR APPS FOR THE CLOUD
Questions to Consider
Application State
Application Scale
App Dependencies
Latency Requirements
Data Sensitivity
Some Easy Cases
e.g., web site sharing public data
SLA Requirements
Regulation & Compliance
Often, Forklift Approach
Will Not Work
Careful decomposition needed
QUESTIONS TO CONSIDER
Application Design
Application Scale
•Durable state must be replicated (directly or a replicated store)
•Designing for cloud is different – likely incurs migration/design costs
•App must scale horizontally (scale-out), not vertically (scale-up)
•App should be segmented; not monolithic in design
•Scale should account for seasonality of demand
Application
Dependencies
•App must be able to run in the cloud with no special hardware needs
Latency Requirements
•Shared cloud systems may not guarantee uniform/low latency among
components
Data Sensitivity
•Data may require encryption to host sensitive data public cloud
•May need to segment data as in-cloud and on-premise
SLA Requirements
•Service level requirements of cloud may matter (how many 9’s?)
•Availability and reliability requirements
Regulation &
Compliance
•Location and type of cloud matters
•Potential legal restrictions upon data based on location
•Potential tax implications with using the cloud
Slide 23
AND THERE IS THE “NONE TECHNICAL”
STUFF
Cost/Revenue
Security
Provider Lock-in
Liability
Licensing
And more…
•OPEX vs CAPEX
•Longer time to ROI
•Remunerating and incentives for your sales force
•Who do your customers trust?
•How transparent should you be?
•Real vs perceived concerns?
•Lock-in is equal among providers. Or is it?
•IaaS is more portable than any other form of cloud. But at what cost?
•Continue to also sell on-premise?
•Do you understand the SLAs and the outcome when they are breached
•Who is to blame? How do you prove it?
•Can customers get a “cloud credit” for on-premise licenses
•Which model do you expose?
•Support 24x7?
•New geographies?

Slide 24
A “TYPICAL” ADOPTION CYCLE
?
•
•
•
•
What is cloud? What is my strategy?
Do I need IaaS, PaaS or SaaS?
Go for public or private cloud?
Which provider?

the journey Microsoft is trying to help companies with…
Understand Why
Cool is not good enough
Pick an Opportunity
Sell Value not Platform
Pick a Provider
Trust in Microsoft
Migrate an App
Deliver Value
Support a Customer
Prove a Point
Establish Relationship
Confidence in Provider/Technology
Do More
Slide 25
SUMMARY
Slide 26
SUMMARY
• Many scenarios make sense for the cloud – it is not just
about elastic computing
• Many clouds to choose from
• Microsoft believe PaaS is the right one
• Many things to consider when making the move
