9Locating Cloud Computing in Gartner's Hype Cycle
10Cloud Computing – “... data is mostly
resident on servers 'somewhere on the
Internet' and the application runs on both
Internet
the 'cloud servers' and the user's browser.”
Eric Schmidt
The Information Factories
• George Gilder
• Wired 14.10 2006
• The desktop is dead.
Welcome to the Internet cloud...
11Okay let's build a Cloud!
Okay,
• 1: Gather all your
y
hardware, software
and data in one place
• 2: Make it all work
together seamlessly
• 3: Securely and
efficiently deploy
applications to
competing customer
bases
12Outside the Cloud (Google)
13Inside the Cloud (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
7,000+ cabinets
• ...and that's just the space/power/cooling!
• Tens of thousands of CPU cores, TBs of
memory PBs of storage,

applications, millions of users, ...

15Cloud
C oud Principles
c p es
• Efficiency above all
• Services are generalized to a level sufficient
to sustain volume
> General purpose services emerge from Appliances
• Consistent stable abstraction layer
• Services are composable
• Locality of compute, data, and network is
specifiable by consumer
• Elasticity
> Risk of unpredictable demand is shifted to cloud provider

17Okay I want my own cloud...
Okay, cloud
...what do I do next?
• Define your cloud IT/business model
• specify public & private components & processes
• Define your goals
• financial, consolidation, “green computing”, etc
• Build a POC
• Select “cloud-friendly” applications
• Architect implement and then manage it
Architect,
• Use open APIs, and open source software within the
cloud...design with interoperability in mind
• Stay away from proprietary API extensions
18What's Sun's Cloud Experience?
• Internally,

a e dep

oud s y e
computing for 30K employees, for 5+ years...
> ...but we didn't call it a “cloud”
• Built and announced Open Cloud Platform (Mar 09)
> provides public Compute & Storage cloud services
> exploits Sun's open source OS, virtualization, and
infrastructure technologies
• Sun

19However...
• As with virtualization today, cloud computing will
> expose and aggravate organizational issues
– IT tribalism & territoriality
– budgetary constraints and decisions, procurement models
> conflict with outmoded policies & regulations
• And be careful with your analogies & metaphors...
> ...bad
bad design decisions can lead to storms and
widespread destruction!
