This document discusses cloud networking and related technologies. It introduces cloud computing models including Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). It describes cloud-enabled networks which use pre-built public cloud infrastructure and cloud-based networks which are software-defined and controller-based. Open network operating systems allow software-defined controllers to manage entire networks. Cloud networking provides reliable, scalable connectivity and virtual private networks through technologies like MPLS.

- 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 .
