only a select group of cloud-wielding Internet
giants has had the resources to scoop up huge
masses of information and build businesses upon
it Humanity emits the data, and a handful
of companies the likes of Google, Yahoo!, or
Amazon.com transform the info into insights,
services, and, ultimately, revenue And
they Google add on new clusters four new
data centers this year alone, at an average cost
of 600 million apiece From Google and the
wisdom of clouds, by Steven Baker -

• Anyone can become a broadcaster
• Infrastructure provider deals with scalability,
  availability, licensing, etc
• Analogue to Cloud Computing
• Broadcasters developers provide music
  applications
• Cloud Computing provider puts the infrastructure
  and charges per use
• First step towards democratization of services
• Whoever has content can distribute/benefit from
  it
• Still the infrastructure provider business is a
  big guys game

Why Cloud Computing ?

• Innovative business models require a utility-like
  intelligent infrastructure that embraces
  complexity to be successful in the competitive,
  fast-paced, services-based global economy.
• ECONOMICS Small up front investment and can be
  billed by consumption. Reduction of TCO allows
  clients to pursue operational efficiency and
  productivity.
• RISK MANAGEMENT Small up front commitment allows
  clients to try many new services faster and
  choose. This reduces big failure risks and
  allows clients to be innovative.
• TIME TO MARKET Adopt new services quickly for
  pilot usages and scale quickly to global scale.
• INFORMATION SOCIETY Value-added information
  generated by collection and analysis of massive
  amounts of unstructured data.
• UBIQUITOUS SOCIETY Accessible via a
  heterogeneous set of devices (PC, phone,
  telematics..)

Because it makes sense !!!

Why now ?

• Broadband networks
• Adoption of Software as a Service
• Salesforce.com
• Web 2.0 mindset
• Fast penetration of virtualization technology for
  x86-based servers
• Virtual appliances
• General purpose on-line virtual machines that can
  do anything

12
Is it really new ?

• Massive scale resource sharing over the Internet
• Sound a lot like grid computing, yet

• Grid
• Highly specialized resources that need to be
  shared by thousands researchers
• Large data sets
• Sharing is a goal
• In many cases, providers are also consumers
• Interoperable by design

• Cloud
• Reducing CAPEX, OPEX, time to market
• Millions of users that share to save not for the
  sake of sharing
• Providers want market share and customer lock-in
• Need for interoperability driven by customers

Unfortunately, at least to date, the methods
used to achieve these goals in todays commercial
clouds have not been open and general purpose,
but instead been mostly proprietary and
specialized for the specific internal uses (e.g.,
large-scale data analysis) of the companies that
developed them. The idea that we might want to
enable interoperability between providers (as in
the electric power grid) has not yet surfaced.
Grid technologies and protocols speak precisely
to these issues, and should be considered wil
l move towards a mix of microproduction and large
utilities, with increasing numbers of small-scale
producers (wind, solar, biomass, etc., for
energy for computing, local clusters and
embedded processorsin shoes and walls?)
co-existing with large-scale regional producers,
and load being distributed among them dynamically

The pillars of CC (according to RESERVOIR)

• Separation
• Cloud computing providers lease resources on
  pay-per-use basis but do not expose
  infrastructure details to customers or partners
• Cloud computing consumers use leased resources
  without exposing details of their applications to
  providers
• Isolation
• Given the hosting nature of cloud computing
  providers, consumers need mechanisms and
  warranties that their application are isolated
  from others that are being hosted in the same
  infrastructure
• Elasticity
• Cloud computing providers should automatically
  adjust the resources allocated to a particular
  application according to elasticity rules
  provided by cloud computing consumer
• Federation
• To overcome the finite amount of resources
  available locally, cloud computing providers
  should be able to collaborate among themselves
  and share their resources

Five computers ?

• "I think there is a world market for about five
  computers"
• Attributed to Thomas J. Watson, IBM
• In a sense, says Yahoo Research Chief
  Prabhakar Raghavan, there are only five computers
  on earth. He lists Google, Yahoo, Microsoft, IBM,
  and Amazon. Few others, he says, can turn
  electricity into computing power with comparable
  efficiency
• Steven Baker, From Google and the wisdom of
  clouds
• The World Wide Web is becoming ONE vast,
  programmable machine. As NYU's Clay Shirky likes
  to say, Watson was off by four
