SDN Remains Unbeatable!

The cloud is growing bigger and bigger and traditional networking cannot keep pace with it. SDN provides much more power to enterprises allowing them to do many things.

In 2016, it is expected that the adoption of softwaredefined networking (SDN) will increase as service providers and enterprises show more interest in this technology solutions. As service providers are analyzing the real business values of software defined networking and service providers are looking for flexibility, automation, visibility, revenue generation.

Over the years, SDN has been moving very fast and has become critical because enterprises are looking to get more value from their investments, networking and data centers. It is critical because data centers are growing at an alarming rate and enterprises need to move with the times.

Enterprises and service providers will adopt SDN as they see it as a way to make their private cloud work better for them. SDN has become an inevitable plan from a practical and professional perspective.

The cloud is growing bigger and bigger and traditional networking cannot satisfy the requirements. SDN is the future trend because it provides much more power and allows enterprises to do many things, which can’t be done today.

SDN is the paradigm that can scale up / scale out and allow enterprises to keep up with data centres. The traditional network is not adequate because it is the hardware-defined network; however, software can change the whole network.

SDN goes open source

Software-defined networking platforms are increasingly open source. Being open involves giving customers a choice so they’re not restricted to a proprietary solution.

SDN, where networking is controlled through soft- ware or virtualization, comprises three vectors: programmability, the OpenFlow protocol and virtualization.

SDN is also multi-tenant, while using the analogy of a multitenant apartment building. You want to use the same IT infrastructure for multiple tenants.

The goal of SDN is to allow network engineers and administrators to respond quickly to changing business requirements. SDN provides the capabilities to shape traffic from a centralized console, bypassing the need to configure individual switches. This allows services to be delivered where they are needed, when they are needed – with less room for human error.

By definition, SDN seems like a no-brainer. It makes perfect sense for organizations to strive to quickly adapt to changing business requirements, so why not implement SDN tomorrow?

Communications service providers have long wished to drive down the operational cost (Opex) of their networks and increase the agility and speed with which they deliver new services. Their concern to achieve a programmable network that can be reconfigured quickly, easily and cost-effectively to meet new customer and service demand is driving huge interest in technologies such as SDN and NFV these technologies promise to revolutionize network operations through automation and application programming interface (APIs).
