This document discusses cloud computing and provides examples of different cloud models. It defines cloud computing as data and applications existing on remote servers accessed over the internet. It outlines various cloud service models like software as a service. The document also cautions that while cloud computing offers benefits, it can also exacerbate organizational issues and conflict with outdated policies if not implemented carefully. It concludes by presenting different models for how organizations can leverage and own cloud resources.

2. Everyone is Talking About Cloud Computing
Software as a Service
Platform as a Service Storage as a Service
Grid Computing
Database as a Service Virtualization
Utility Computing Application Hosting
Infrastructure as a Service

3. Cloud Computing – “... data is mostly
resident on servers 'somewhere on the
Internet' and the application runs on both
the 'cloud servers' and the user's browser.”

5. Okay, let's build one!
• 1: Gather all your
hardware, software
and data in one place
• 2: Make it all work
together seamlessly
• 3: Securely and
efficiently deploy
applications to
competing customer
bases

7. Or like “SuperNAP”?
• 407,000 square feet of space
• 250 MVA Switch owned substation
• 146 MVA of generator capacity
• 84 MVA of UPS supply
• 30,000 tons of system plus system cooling
• 4,500,000 CFM
• 30 cooling towers
• 1,500 watts per sq. ft. density
• 7,000+ cabinets
• ...and that's just the space/power/cooling!
• Tens of thousands of CPUs, TBs of memory,
PBs of storage, Thousands of applications,
millions of users, ...

8. Cloud Characteristics
• SLA-based multi-tenant business model for users
• Safe & Secure, on-demand, self-service
• Self-configuring & provisioning, self-healing
• Comprehensive, open, standardized APIs for
developers
• Fully virtualized and scalable
> applications, operating systems, network, storage
• Hide the complexity of
> Create, start/stop, import/export, snapshot, reboot,
backup/restore, move, destroy

9. However...
• As with virtualization today, cloud computing will
> expose and aggravate organizational issues
– IT tribalism & territoriality
– budgetary constraints and decisions
> conflict with outmoded policies & regulations
• And be careful with your analogies & metaphors...
> ...bad design decisions can lead to storms and
widespread destruction!
