SDN Technologies - How to get started?

IT firms can get help from the trusted channel partners. They can also attend events which are focused on implementing and applications of SDN technologies, such as the Open Network Summit and Open Network User Group.

SDN (Software-defined networking) is the latest networking approach that removes the static and intricate nature of distributed network architectures. It is achieved by using a standard based software concept between the fundamental data forwarding plane and network control plane. This modern technology offers IT firms a number of powerful and controlling tools to enhance the effectiveness the networks. Various options are present for using SDN tools for new definite applications, IT projects and in the network.

SDN directs and controls the fact that the static architecture of conventional networks is ill-suited for the active computing. Therefore, the storage needs of present world are increasing such as in campuses, carrier environments and data centers. The key computing trends are increasing the need for a new network pattern.

Implementation of SDN technologies appears challenging and complex due to the lack of standards and complex set of protocols, as along with the introduction to new and competitive products from different vendors. However, in order to become an essential part of networking architectures in the data center, WAN and campus SDN is rapidly growing and developing.

To start with SDN technologies, IT companies or professionals should start slow. They should choose a good application, acquire experience and then expand their SDN footsteps. For evaluation of particular applications, ask which one could benefit most from the security, programmability and flexibility that SDN offers.

SDN offers special applications that are beneficial for IT firms, such as:

• Data center builds: During the manufacturing of a new data center, SDN is the basic part of the integration between server, applications and network storage. OpenStack deployments include SDN capabilities to expand networking functionality.
• Switching to private cloud: For private cloud operations to be competitive with public cloud services, install SDN to enhance centralized management and automation.
• Improve performance of network: Scrupulous applications like big data analytics. Big data applications like Hadoop are vastly distributed and they need low latency among processes to increase performance. SDN also provides application prioritization tools to enhance the network performance.
• Enhance internal data center security: Increased traffic can allow cyber attacks to transfer the susceptible applications through the data center. In this condition, SDN’s white box switch provides micro segmentation of virtual machines and applications for inner data center traffic.

• Cost efficient network monitoring: White box switches of SDN software lowers the expenditure and enhances the flexibility of network monitoring tools to regulate the network traffic.
• Boost the branch WAN performance: The branch with more traffic going directly to the internet and alters the traffics patterns. This is because organization needs to upgrade their WAN links. SDN WAN provides higher reliability and enhanced security for Integrated circuits.
