What is Cloud Computing

Cloud computing is an umbrella term used to refer to
Internet based development and services.

CONTINU...

 Used in Online tools for email,productivity
software, business applications, and data
storage

 Eliminates costs related to on-site
installations of hardware, software, and
IT support staff

 Available from any location and device
with an internet connection

Who are all in the Cloud?

 Online email accounts (Gmail, Yahoo)
 Social networking sites (Facebook,
Twitter)
 Photo sharing sites (Flickr, Picasa)
 Search engines (Google, Bing)
 Productivity software (Google Docs)
 Personal finance software (Quicken,
online banking and bill paying tools)

CHARACTERISTICS:
A number of characteristics define cloud data,


applications services and infrastructure:

Remotely hosted: Services or data are hosted
on remote infrastructure.

Ubiquitous: Services or data are available
from anywhere.

Commodified: The result is a traditional
utilities, like electricity - you pay for what you
would want!

Economics:

 Cloud computing users avoid Capital
  Expenditure (CapEx) on hardware, software, and
  services when they pay a provider only for what
  they use.

  Shared infrastructure and costs, low
   management  overhead, and immediate access to
   a broad range of applications.

Layers:
(i) Client :

 A cloud client
  consists of
  computer hardware
   and/or computer
software that is
specifically
designed for delivery
of cloud services

(ii) Application :
 Cloud application services or "Software
  as a Service (SaaS)" deliver software as a
  service over the Internet.

 eliminating the need to install and run the

  application on the customer's own
  computers and simplifying maintenance
  and support.

(iii) Platform :

 Cloud platform services or "Platform as a
  Service (PaaS)" deliver a computing
  platform and/or solution stack as a
  service.

 It facilitates deployment of applications
  without the cost and complexity of buying
  and managing the hardware and software
  layers.

(iv) Cloud Infrastructure as Service:
 "Infrastructure as a Service (IaaS)"
delivers computer infrastructure,
typically a platform virtualization
environment as a service

Rather than purchasing servers,
software,network equipment, clients
instead buy those resources as a fully
outsourced service

The service is typically billed on a
utility computing basis and amount of
resources consumed

(V) Server :

The servers layer consists of computer
  hardware and/or software  products
that are specifically designed for the
  delivery of cloud services

 It including multicore processors, cloud
  specific operating systems and
  combined offerings

Hybrid Cloud :

 By integrating multiple cloud services users
  may be able to ease the transition to public
  cloud services while avoiding issues such as
  PCI compliance.

 A hybrid cloud environment consisting of
  multiple internal and/or external providers "will
  be typical for most enterprises".

Cloud storage :

Cloud Storage is a


model of networked
Computer data
storage.

Data is stored on


multiple virtual servers,
generally hosted by third
parties, rather than being
hosted on dedicated
servers.

The Intercloud :
 The Intercloud is an
interconnected global
"cloud of clouds" and
an extension of the
Internet "network of
networks" on which it is
based.

Issues :

(i) Security data storage and transmission
encryption, user authentication, and
authorization (data access) practices.

worry about the vulnerability of remote data
to such criminals as hackers, thieves...etc

(ii)Reliability – To avoid the loss of data using
redundant storage techniques, but it is still
possible that a service could crash.

(iii) Ownership – In  cloud, some people worry
      that they could lose some or all
     of their rights or be unable to protect the
     rights of   their customers.

(iv) Data Backup – Cloud providers employ
     redundant servers and routine data backup
      processes.
   some people worry about being able to
     control their own backups .

Data Portability and Conversion – Porting
and converting data is highly dependent on the
nature of the cloud provider’s data retrieval
format.

Multiplatform Support – An issue for IT
departments using managed services is how
the cloudbased service integrates across
different platforms and operating systems.

Intellectual Property A company invents
something new and it uses cloud services as
part of the invention. Not secured in cloud.

Future of cloud Computing:

Cloud computing is still in


its infancy, and the future
is still being defined.
Made possible due to high-
speed Internet.

No matter the country, anyone can
compete in this market and define its the
future.

Future of cloud Computing...
 Technology will evolve from services
into full-fledged operating systems.

Google, Microsoft, and Apple are
three likely contenders in the future of
the industry.
