Software Defined Networking (SDN) is not just one thing; rather, this is an umbrella term which describes several types of network technology which aim to make the network both agile and flexible to match that of storage infrastructure and virtualized server of the data center. SDN is an approach which allows network administrators to initialize, control, and manage networks through networking and open interfaces.
Perhaps the most apparent benefit to using software defined data centers is that you have control. Nowadays, it’s difficult to feel like you have a say in what goes on with your computers, internet, and networks. SDN provides you with control over more than just your private networks, though because you also have control over which internal IP address range you use, the configuration of your virtual routers, and your network gateways connectivity. Regarding the IP allocation, you’ll have the wonderful ability to choose different IP addresses for different, and designated, tenant applications.
Not only does it provide you with optimal control, but it is also flexible. You’re able to shape and alter network topographies without causing any changes to the underlying network configuration or topography of your software. Although you won’t be changing the physical network configuration of the network, you don’t have to worry about losing any flexibility. Because of this, you’re provided with the excellent ability of creating your own environment without network engineers. With SDN, you’ll be saving yourself an incredible amount of money because you won’t need to hire network engineers to do the exact same job or you.
The main problem which software defined storage is that static architecture, meaning the architecture has no dynamic memory allocation, of traditional networks does not support dynamic networks.
Software defined networking is most often associated with the OpenFlow protocol; however recently, there are many companies which have strayed away from OpenFlow and have begun delving into other techniques, such as Cisco Systems and Open Network Environment.
There are many benefits to using software defined networking (SDN), which began in the year 2000. Since then, it has become a major method which allows you to have complete control over the infrastructure of your virtualized server and network. That being said, what exactly are you waiting for? Get out there and get started with software defined networking.
