With enterprises looking to scale business, redesigning their networking strength is today the prime focus of attention. Many large scale enterprises relying on excessive data have transformed from a traditional network to a more refined and automated softwaredefined network. In an era where businesses are transforming to a more agile set of operations, using the traditional hardware oriented networking does not add up for next generation of business efficiency.
Software defined networking(SDN)allows organizations the advantage of having their networks just as agile and ready for excessive loads, multiple devices, big data usage while facilitating on demand networking needs.SDN implementation allows enterprises multiple benefits including more efficient networks, agile and faster network solutions all of it with a highly secured network with efficient cost savings.
Here is how software defined networking allows enterprises to unlock their potential and drive efficiency, retain agility and save on costs while reaping the benefits of a software based network.
SDN and enhanced efficiency
Software defined networks with their central network provision options make them easier and more efficient to implement over larger networks. SDN allows for a centralized enterprise management control system where SDN tools manage remote networks leading to seamless maintenance of networks like WANs. Unlike in a traditional network setup where controlling a distant wide area networks may be a challenge, SDN allows for a seamless approach with its automation capabilities from one central location.
SDNs not only allow to greater network efficiency in remote locations, but also ensure flexibility in how the network is operated. The approach allows control of both physical and virtual devices from a remote location improving efficiency, lowering latency and downtime. Any performance oriented challenges are also easily identified, thanks to a central control API with agile solutions offered without impacting the regular networking activities.
Improved speed and agility
Software Defined Networking increases network responsiveness, helping enterprises scale speed and agility in performance. SDNs make use of functionalities like virtual network functions (VNFs) and frameworks like OpenStack to improve their performance times. As more and more enterprises aim to adopt an agile and responsive networking environment, the popularity of SDN is witnessing a massive upside. Adding to any physical networking needs like switches or routers can be automated by SDNs instantly without investment in physical devices. With a customized network routing system, SDN network administrator can run multiple checks on the network as per the needs of the organization. For example, if an organization wants to implement multimedia transmission services, SDN allows for an easier implementation of quality of service with matching network responsiveness for seamless user experience.
Since SDN virtualizes the physical network enhancement needs, performing an upgrade to implementing any such multimedia needs is agile and achieved in real-time. Every such configuration enhancement is snap-shot in various times allowing the administrator to recover from any upgrade fails instantly. Hence improved speed and agility is equally mapped for upgrades as well as downgrades to ensure network compatibility is optimum at all times with SDN.
Low operational costs of SDN
SDNs allow for cost savings as they ensure lower operating expenses on account of reduced expenses on physical infrastructure. Any network up gradation like use of routers, switches, etc., need not be physical and are virtualized thanks to the power of software defined networks. All such hardware related expenses account for substantial cost savings for the organization in a long run. Enterprises having wide networks and global operations are the ones that seek the maximum cost benefits of SDN implementation. Secondly with the use of SDN, network services are available for application owners in pre-defined packages that can result in lower human resource for the in-house networking team for an enterprise.
The initial investment for implementation of software defined networking is also minimal compared to traditional networking. For organizations transferring from a traditional network structure can make use of their existing network devices within SDNstructure. SDN solutions by and large support Layer 1 through Layer 3 networking models which adds to the advantages of organizations. Enterprises need not escalate costs by buying additional hardware while optimizing existing network hardware for SDNimplementation.
Conclusion: Implementation of software defined networking is a progressive step that enhances the networking capabilities of an enterprise while helping scale efficiency, agility, and cost savings.
