3 reasons software-defined networking’s future is bright

3 reasons software-defined networking’s future is bright
Since its inception around 2004, software-defined networking (SDN) has experienced steady adoption for good reason. Traditionally, networks built using static architecture can be complicated, costly and challenging to troubleshoot. However, by using software to design, implement, and manage networks, it’s possible to create new network flexibility and control levels while reducing expenses.

You can see evidence of the appeal of SDN in its growth rates. For example, research firm IDC estimates that the worldwide data center SDN market will be worth more than $12 billion by 2022 at a CAGR of 18.5%. When we dig a little deeper, we can see three trends that are contributing to this growth. Which of these applies to your customers?

1. The rise of Kubernetes and containerization
Kubernetes and containers are all the rage for application development and deployment. Unlike other virtualized environments, containers can be built to include only code and computing processes necessary to run the app. In addition, containerized applications can run on a single operating system, with each container sharing the operating system kernel with the other containers. For example, deploying containers via VMware vSphere and managing the environment with NSX allows your customers to do more with less, reducing the amount of hardware and even virtual machines typically used for apps. This all adds up to less overhead, increased portability, higher efficiency and increased developmental agility.

2. Increasing security concerns
Saying that cybersecurity is essential today is an understatement. Organizations are collecting, storing and analyzing more data than ever—including intellectual property, personally identifiable information (PII), protected health information (PHI) and more. The prize of all this data is too tempting to criminals. By tapping into software-defined security within your SDN, you can protect your customers easier and more affordably than ever. For example, VMware NSX Distributed Firewall employs micro-segmentation to apply L2, L3, and L4 rules to IP addresses, MAC addresses, VMs, switches, directories and more. Not only does this allow you to create additional layers of security, but it can also reduce expenses associated with having to purchase and maintain physical security solutions.

3. Hardware is expensive
Both previous trends are heavily influenced by the expenses associated with traditional networking infrastructure. SDN allows your customers to dramatically reduce networking hardware, thus eliminating the initial expenses while significantly reducing complexity (lowering admin costs). In fact, in addition to reducing the need for expensive hardware, SDN carries with it the promise of advanced services, centralized provisioning and greater ability to shape and control data traffic.

VMware NSX makes SDN easy and affordable
If your customers see the benefits of containerization and Kubernetes, are concerned with security, interested in simplifying networking management, but don’t have the budget to buy expensive hardware, an SDN through VMware NSX is the solution they need.
