Global SD WAN Case Study

Cloud computing has set a trend in the information technology arena that has sparked the interest of all who utilize the internet on purpose and unsuspectingly. Initially, the primary purpose of cloud computing was to provide a centralized data bank that organizations could use for quick data access. Its use has been quickly adapted, however, beyond business use to become the first option for personal use. The advantages and disadvantages of implementing such a shift from business to personal are varied, yet, statistically, according to the CISCO Global Cloud Index: Forecast and Methodology, 2014-2019 White Paper, its public use is on the rise. The report notes that “by 2019, 56 percent of the cloud workloads will be in public cloud data centers, up from 30 percent in 2014 and by 2019, 44 percent of the cloud workloads will be in private cloud data centers, down from 70 percent in 2014”. Though disadvantages with regard to data security is prominent, users have deemed that its implementation will still promote greater benefits than loss.

Software defined networking is a new concept that redefined the current network device architecture and the way they behave. Due to the exponential growth of the Internet and services attached to this worldwide infrastructure, a number of issues have cropped up in modern day networks. This paper discusses a few of these limitations and how the software defined networking approach tries to alleviate them. OpenFlow, released in the year 2008, is a commercially viable implementation of this concept that is being well received by the networking industry at large. The paper also discusses the OpenFlow protocol, its implementation and the challenges facing its widespread acceptance

Integration is just one of the challenges. A sophisticated network configuration is needed to transfer data between the private and public clouds that comprise the hybrid environment. Not only must the network transfer the data securely, but it must deliver a seamless user experience. In addition to a fast and reliable network, failover capabilities are needed to handle any system or network outages.

In this paper, it Delivering innovative IP-based services and applications to enterprises requires a robust and secure MPLS-enabled virtual private network (VPN) or IP-based VPN. Emerging virtual private cloud (VPC)–based services also rely on the underlying network, which is the environment in which any cloud service must exist. The secure connectivity of a private IP VPN service combined with the data security supplied from a VPC service ensures that a customer's data and applications have the high availability, reliability, and flexibility to connect to any enterprise resources.

Software-defined networking (SDN) is next evolving technology for the cloud computing as it provides a centralized system to manage the network. Scalable monitoring and dynamic reconfiguration requirements of the network makes SDN a perfect choice (Amna Riaz 2017).

Stratoscale’s unique software-only solution enables the creation of private cloud in minutes -- facilitating scale-out, simplifying operations and become “The Cloud”

Virtualization has made network management more challenging, and it’s more and more difficult to consistently apply firewall and content filtering policies. When you add in complexities such as securing BYOD devices, the security problem is intensified. Software-defined networking (SDN) is next evolving technology for the cloud computing. SDN is an umbrella term covering several kinds of network technology aimed at making the network as agile and flexible as the virtualized server and storage infrastructure of the modern data center. The SDN Controller provides a centralized system to manage the network. The network administrators are empowered by SDN to easily access and manage individual flows by facilitating them to implement monitoring applications, i.e., firewall and IDS. Furthermore, scalable monitoring and dynamic reconfiguration requirements of the network in cloud makes SDN a perfect choice (Amna Riaz 2017).

Using “Poncho” tool, the developers of it have created an interface which will help to improve the effective communication between cloud users and cloud operators. Also, making the operations on the tool very easy for the stakeholders to understand and use. Some of the open source cloud models for applications are ideal for cloud operators, since the users services are tolerant to failures for instances. While this cloud model is what lot of users need in order to reach their goals. So, using this tool we can overcome the operational and usability difficulties. As these are primarily related to private clouds. Poncho tool will make API driven communication using the instances. Now, we will go more in details with every aspect of Poncho development, its working and some of the primary challenges related to private clouds.

The report list out the various tangible and intangible benefits of implementing cloud. It also looks at the risks of implementing the cloud and measures to mitigate these risks. An implementation roadmap to transition to the cloud is outlined. The timeline is estimated based on implementations done by other enterprises. To further reiterate the significance of the proposal, the case study of implementing cloud by Dish TV is presented. Dish TV has benefited immensely by this initiative. DEN Networks having the same line of business and similar organization

Cloud computing is already at the center of new data center evolution because large amounts of information can be stored in cloud. It is actually estimated that 1/3 of all data will go through cloud by 2020. This will lead to a rise in global cloud revenues as well as the amount of money firms spend on cloud computing and innovation. The development will also see many organizations come up with ways to enhance cloud infrastructure to enhance compute density, ultra-low latency and power density. The most common networking attributes of cloud include; low latency, programmable management, scalable, Open APIs and Self-healing resilience. Cloud networking scaling is achieved using topologies from wide ranging nodes that provide non-resistive fabric

To reduce networks problem, we can use Software Defined Network. Software-Defined Networking (SDN) is an outgoing architecture that is progressive, manageable, cost-effective, and painful, making it ideal for the high-bandwidth, cheaper to build, powerfully faster and more skilled dynamic nature of today 's applications [2]. SDN demands to reduce this effort dramatically [4]. SDN is called the birds-eye perspective on a network. The idea behind it is middle "intelligence" that is able to looking the big picture and is thus able to control and optimistic data streams better and efficiently. Adopting an SDN methodology has a countless of benefits including facility, scalability, thickness, and performance [4]. In addition, a growing network

The project focuses on the cost effective enhancement of enterprise network security via OpenFlow controlled switches and specialized SDN applications running on a controller. The project will investigate on securing the network from various attacks like ping attack, TCP SYN attack, Distributed Denial of Service (DDoS), DHCP attack. Different security measures will be discussed through which the user can establish a secured network. These security measures will be implemented over SDN.

Google had big problems like high financial cost managing their data centers, delayed caused by rebuilding connection after link failure. Google went ahead and implemented SDN. In 2013, they built their hardware and wrote their own software and surprised the industries by announcing that SDN is possible in production. They named it B4, a private WAN connecting Google’s data centers across the planet. B4 has a number of unique characteristics like Massive Bandwidth requirement, Elastic traffic demands and full control over edge servers and network.
