Software-defined Networking (SDN): The Future of Networking

Why SDN is the Future of Networking?

Over the past two decades, networking has been severely limited- it simply could not keep up with new demands from businesses in an increasingly digital world. However, that is all about to change thanks to the creation of Software-Defined Networking, or SDN. SDN allows people (particularly businesses with large IT systems) to control network behaviour through a handy piece of software, instead of having to go into the network infrastructure and alter things manually. Networks are getting smarter, and as a result, they can be controlled from a central point, instead of having to connect each device individually.

This is great news for businesses, since it means they will no longer have to shell out for on-site services that can now be easily carried out remotely. Networking costs can quickly add up, and account for around 10-15% of most companies’ IT costs. However, by making use of SDN, which is far less time-consuming than manual access, it’s possible to cut that figure in half- a tempting prospect for any business. As a result, it is reasonable to assume than many businesses will want software-defined networking services included in their as-a-service platform.

This additional feature is just one reason why we will see even more of a trend towards SDN in the outsourcing industry. It is mainly IT outsourcers who have made the most use of SDN so far, and it also has multiple benefits for them, too. These include making their operations more efficient, cutting operational costs, and providing a more competitive service.

It’s not just the savings that SDN offers, though. As well as increasing efficiency, SDN also allows network services to be made much more flexible. Whatever the client needs, IT outsourcers will be able to provide with minimal fuss. What’s more, these services can then be adapted in real-time in response to changing needs and circumstances. That’s because SDN incorporates multiple capabilities, from network design and functions to service platforms and data centers. In short, it takes all the best features from a number of different areas, and  puts them to use in a whole new way.

By far the biggest benefit of SDN is that it increases network operators’ agility. This means they are both more efficient at what they do, and also that they have increased control over network infrastructure. Thanks to this, they can offer better value to their customers, and thereby draw in new clients. There is certainly a large market out there- according to some estimates, the international SDN market for enterprises and cloud service providers could reach a total value of $8 billion by the end of next year.

For anyone involved in IT outsourcing, then, SDN is a valuable tool to have their belt. By offering customers more bang for their buck, SDN looks set to become the industry standard- and IT providers should therefore consider making it a core part of their service before someone else comes in and fills the gap in the market before them.
