What are the advantages of SDN?

The bigger promise of software-defined networking (SDN) is that it’ll centralize and simplify control of enterprise network management. Lots of vendors would be claiming differently, but the most commonly quoted advantages of software-defined networking would be traffic programmability, greater agility, the ability to create policy-driven network supervision, and implementing network automation. For more details on SDN, you should opt for the training courses offered at the SPOTO Club.

Below mentioned are some of the advantages of software-defined networking:
1. Centralized network provisioning.
Software-defined networks would be providing a centralized view of the entire network, making it would be quite easier to centralize enterprise management and provisioning. Through abstracting the control and data planes, SDN might be accelerating service delivery and providing more agility in provisioning virtual and physical network devices from a central location.

2. Holistic enterprise management.
Enterprise networks need to establish new applications and virtual machines on-demand to accommodate new processing requests like those for big data. SDN would be allowing IT managers to experiment with network configuration without impacting the network. SDN would also support the management of physical and virtual switches and network devices from a central controller, something you couldn’t do with SNMP. SDN would be providing a single set of APIs for creating a single management console for physical as well as virtual devices.

3. More granular security.
One of the advantages of security defined networking that would be appealing most to IT managers would be centralized security. Virtualization has made network management much more challenging. With virtual machines going and coming as part of physical systems, it is considered to be more difficult for consistently applying firewall and content filtering policies. When you would be adding in complexities like securing BYOD devices, the security problem would be compounded.

4. Lower operating costs.
Administrative efficiency, improvements in server utilization, better control of virtualization, as well as other benefits, should be resulting in operational savings. Although it might still be early for showing real proof of savings, SDN should lower overall operating costs and end in administrative savings since many of the routine network administration issues might be automated and centralized.

5. Hardware savings and reduced capital expenditures.
Adopting SDN could also be giving new life for existing network devices. SDN would be making it easier for optimizing the commoditized hardware. Existing hardware can be repurposed for mounting instructions from the SDN controller, and less expensive hardware could be deployed to greater effect. Because new devices essentially become white box switches with all the intelligence which would be centered at the SDN controller.

6. Cloud abstraction.
Cloud computing is here to stay, and it is going to be evolving into a unified infrastructure. By abstracting cloud resources utilizing software-defined networking, it would be easier to unify cloud resources. The networking components that would be making up massive data center platforms could all be managed from the SDN controller.

7. Guaranteed content delivery.
The ability to shape as well as control data traffic is considered to be one of the primary advantages of software-defined networking. Being able to automate and direct data traffic makes it easier for implementing quality of services (QoS) for voice over IP as well as multimedia transmissions. A high-quality video streaming would be easier because SDN would improve network responsiveness to ensure flawless user experience.

For more details regarding the SDN and about Cisco Certification, you should opt for the training courses offered at the SPOTO Club. When it comes to IT Certification, SPOTO Club is the best training provider for the same.
