Pay as you go No rent or own
Rapid setup Weeks, not years
Demand-driven capacity Scalable bandwidth, storage, computing cycles
No capital equipment Buying a service, not a server
Flexibility Short term vs. long term
Easier, better data protection Backup, disaster recovery, security
Transfer of risk of misestimating It’s theirs, not hers
Lower development costs Quick deployment of dev and test environments

You build and maintain server from scratch or use packaged
server
You build and maintain server, but can use any
of variety of Microsoft tools
You build capability
within their controlled
environment
Low-level
“clean slate”
Mid-level
Mixed services,
Custom and packaged
High-level

Public Cloud
Works best for:• Seasonal• Event-based• Unknown• Predictable or
unpredictable bursts
Private Cloud
Works best for:• Static, predictable demand• Microsecond precision of
data movement (e.g., stock trading)

• Vendor lock-in, data lock-in, "single-link-in-the-chain" vulnerability
• Security, confidentiality, compliance, auditability• Data storage location (domestic, foreign)• Migrating to the cloud• Difficulty of extracting data from the cloud• Reputation fate sharing• Business continuity, availability• Commercial software licensing• Monitoring and management
Pauline worries about other perils…

Risk vs. Reward
Should you consider the cloud?
![Page 26: Introduction to Cloud Computing for Executives](https://reader036.fdocuments.in/reader036/viewer/2022070316/5561a359d8b42ae1538b4bbd/html5/thumbnails/26.jpg)
Is your technology infrastructure keeping pace with your business growth (or shrinkage)? (Do you know?)
How well is your business adapting to extreme peaks or valleys of customer demand?
How well is your infrastructure meeting the demands of its business users for certain performance levels? (Do you know?)
How satisfied are you with your time-to-market for new business offerings?
Does your organization need to quickly enable a new internal capability?
Do you need to reduce costs to become more competitive? Which costs? Are they CapEx or OpEx?

If these are in your current strategy…
Reduce costs Increase agility, adaptability, reliability Reduce business continuity risk Sharpen focus on business
…you should check out the cloud.
