3. Introduction
• Today Information technology infrastructure working in
various Computing Environment for the business scalability and
security and business continuity with Zero Down time.
• Due to various reasons companies started to adopt the IT
infrastructure as per the technology development.
• There are various computing technologies available in the
Current available Infrastructure that make computing
infrastructure more reliable and scalable and make zero down
time.
• Some of the computing technologies are Cluster computing
,Grid Computing, Cloud computing .
• Cluster computing : Group of nodes having similar attributes
to give a single service to the user.
• Grid Computing : Interconnected nodes to perform a single
Task or centralized resource for sharing or working
• Cloud Computing : Distributed computing over a cloud
network. some of the examples of cloud computing is Google
App Engine, Google Computing engine, windows
Azure,Facebook,Gmail,Yahoo,social Networks.

4. Cloud Computing
• Cloud computing is a distributed computing over a network and
means the ability to run a program or application on many
connected computer at start time.
•Major models of cloud computing are
1. Software as a service
2. Platform as a Service
3. Infrastructure as a service
Infrastructure as a Service (IaaS)
It is lower most important cloud service in Computing
environment. This service will have centralized environment and
provide various service such as server, storage and network, and
other management process.
Some of the Iaas are in the Real time Environment is Google
Computing Engine, Windows Azure.Infrastruture as a service
become very scalable because of the virtualization features .some of
the virtualization Methods are Hyper-V, Xen , Kernel Virtual
Machine.Vmvare ESX/ESXi.

5. Platform as a Service (PaaS)
Platform as a service deployed at the top of Iaas .These
service to develop as application or create a application .these
services comprises of database, developer environment and other
related features which helps user to work in centralized domain .
Real time example for Platform as a service is Google App
engine.
Software as a service (SaaS)
Software as a service deployed at the top of the other two
services. These helps more sophisticated maintenance of
Infrastructure. Some of the examples of Software as a service is
Social network,gmail,yahoo..
Cloud networking is related to this slightly different from these
services but cloud networking is build with help of above
mentioned services..
Cloud networking become very flexible and easy maintainable by
because of network virtualization technologies. These cloud

6. Cloud Models
There are three Types of cloud models which we are using in real
Time environment.
1. Private Cloud
2. Public Cloud
3. Hybrid cloud
Private Cloud : It is cloud which is owned privately and maintained
for a usage of specific purpose. Connection various nodes by their
own media.
Public Cloud : It is cloud which is formed between two predefined
nodes with may helpful to extent the nodes to more.
Hybrid cloud : It is combination of both Public cloud and private
cloud .
Current Information technology environment is working on these
hybrid technology.

7. Network Cloud computing
• Cloud based network environment is very secure and reliable and
scalable environment which helps companies migrate or extent
their branches or location to one place or to new location .
There are two types of Network computing architecture
• Cloud enable network.
• Cloud based network.
Secure Network cloud computing connects various locations
private cloud network and public cloud network.
Normally today network environment are working on the Leased
line,ISDN,MPLS,ATM ,Vo IP, Frame Relay, HDLC.
Comparison and contrasting various network available in industry
MPLS L3 is used across globe because for scalability , reliability
and Redunancy

8. Cloud Enable Network (IaaS or Naas)
Cloud enable Network is prebuilt public cloud with the
router,switches,and with several Packet routing protocols .
• These pre established cloud service is given By ISP. Incase if
company want to conquer a business in new location they can just
extend the private network via those pre built cloud .
• These pre built public cloud runs on packet switched based
routing protocols with infiniband bands which as high redundancy
and reliability
example of the Cloud Enable Network is MPLS (L3).
Multi protocol Labeled switching Layer 3
MPLS L3 is a cloud based architecture and it helps to
establish very secure Virtual private network with
Redunancy,reliability,scalibility .
To establish MPLS Layer 3 network we have set up only router at
our end from the router data is transmitted via Packet switched
routed protocol network in a labeled switched path.
In the MPLS link all the data transmission via packet switched
network only in the labeled path .other than that no data will flow.
This design makes business people to extent the private network

9. Cloud Based network
• Cloud based Service it is a software defined network which
controls the entire routing and packet switching.
Mostly these type of network consists of controller to control
routing operations. These controllers can be controlled by means of
web browser.
• These controller are built control options in presentation layer
interface. Management and other operations can be done from
client side itself. For this just internet connection is enough .
• Cloud based network is very fast to implement when compare
cloud enabled network with same features.
• Cloud based network and cloud enabled network is plays a
important role in built a secure Virtual private network with
security,relaibility,redunancy.
• These types of network plays a important role in today network
environment .
When compared to leased line these type of connectivity gives
between redundancy and reliability in all type of aspects.

10. Open Network Operating system
• Software defined network can be constructed with the help of
controller which runs with the help of open network operating
system.
• Open network operating system these operating system with
software defined controller able options to control the entire network.
• Open network operating system is a Linux based type system with
easy management features.
• Advancement of these things make critical network also very easy
to built and maintain .

11. Conclusion
• Automated cloud based network will establish new link when old
link is down packed can be routed via some other path this make a
link reliable.
• Automation in software defined network with make the cloud
based network with ZERO down time and with no security Breach .
