2. Abstract
In a typical Cloud computing environment the
actual computational power cannot be
realized due to the limited bandwidth of
existing networks.A optical network is
proposed as a key to implementing increased
agility and flexibility into a cloud computing
environment by providing any-to-any
connectivity with the appropriate optical
bandwidth at the appropriate time.

3. Cloud Computing
 Cloud computing is a term used to describe
both a platform and type of application.
 Advanced clouds typically include other
computing resources such as storage area
networks (SANs), network equipment,
firewall and other security devices.
 3 types of services:
1. IaaS
2. PaaS
3. SaaS

4.  Cloud computing also describes
applications that are extended to be
accessible through the Internet.
 Anyone with a suitable Internet
connection and a standard browser can
access a cloud application.

5.  Cloud computing infrastructures can allow
enterprises to achieve more efficient use of
their IT hardware and software investments.
 A cloud infrastructure can be a cost efficient
model for delivering information services,
reducing IT management complexity,
promoting innovation, and increasing
responsiveness through realtime workload
balancing.

6.  The Cloud makes it possible to launch Web
2.0 applications quickly and to scale up
applications as much as needed when
needed.
 The platform supports traditional Java™ and
Linux, Apache, MySQL, PHP (LAMP) stack-
based applications as well as new
architectures such as MapReduce and the
Google File System, which provide a means
to scale applications across thousands of
servers instantly.

7. Photonic Networks
An Introduction

8. Photonic Networks
 Photonic networks are high-capacity
telecommunications networks based on
optical technologies and components that
provide routing, grooming,and restoration at
the wavelength level as well as wavelength-
based services.
 The Photonic network has a photonic
background and makes intensive use of
passive optical networks in the access
network.

9.  Photonic network which are based on WDM
technology are not limited to transport as they also
realize node functions in the photonic regime.
 Photonic networks utilize the independent
characteristics of multi-wavelength network and can
simultaneously accommodate various kinds of signals
including SDH/SONET,ATM,IP.
 Another advantage of the photonic networks is their
flexibity which allows the transmission capacity and
routes to be changed according to changes in
network needs ,for example ,in case of a failure in
part of the network.

10. Bottlenecks in Cloud
Computing

11.  The efficiency of high speed processors and
faster storage devices cannot be experienced
without the high bandwidth and faster
networks.
 Trusting a third party for maintaining sensitive
data needs attention.
 Transmitting each character typed over
internet without any special security feature
also requires concern.

12. Application of Optical
Computing as a remedy
 Photonic networks address the problem of
need for increased bandwidth and need for
faster networks.
 Increase in bandwidth of current electronic
networks increases the cost per bandwidth
and makes it unaffordable.
 Photonic networks helps in reducing the cost
per increase in bandwidth.

13.  As we know photons are much faster than electrons
the thirst for speed in cloud computing environment is
satisfied by them.
 Most people use computers for office use and
manipulation of sensitive data.
 Faster encryption and decryption of data at user side
is not possible with electrical chips.
 This problem is solved by implementing a special
highly efficient photonic chip at ports for faster
encryption of data

14. Conclusion
 This paper focuses on finding an
efficient way to increase the agility of
cloud computing by using optical
networks.
 It also touches on the fundamental
concepts of cloud computing and
optical computing.
