software-defined networking, is it worth the investment? | NTT
25 May 2021
The implementation of software-defined networking with centralized access management delivers tangible benefits. You gain improved quality of service and the assurance of secure and fast device and policy deployment, while at the same time increasing your ability to mitigate risk across your network operations.
Intent-based networking (IBN) adds artificial intelligence and machine learning capabilities to software-defined networking. Using these additional capabilities, business policies are translated into the desired network state using centralized network orchestration software. This centralized network software is leveraged to automatically implement policy-based configurations consistently across the network. With IBN, customized networking baselines can be developed to define the optimal network state for the organization. These baselines are then used to monitor the network to identify network performance issues faster, provide continuous verification and automate corrective action where feasible.
So, what’s that worth? That depends on what your current networking challenges are costing you in terms of operational efficiency and your ability to respond to dynamic change with your current support model and resources.
Most enterprises have witnessed their networks becoming increasingly complex, driven by digital transformation initiatives, more cloud-based applications, a proliferation of a broad diversity of endpoint devices and a demand for an ever-increasing level of service to remain competitive. And yet, a Cisco McKinsey study found that many operational models are still too reliant on manual intervention, identifying that:
- 95% of all network changes are performed manually
- 75% of operating cost is spent on change and troubleshooting issues
- 70% of policy violations are due to human error
Reliance on manual processes can have a major impact on the efficiency of your IT operations, taking up too much valuable time, duplicating effort, creating a high risk of potential human error and increasing overall cost of change.
By automating network changes to thousands of devices and with the ability to continuously verify compliance without human intervention, will take away some of the strain from your IT team, decrease risk and achieve increased assurance and speed of deployment. Monitoring actual performance against granular desired-state baselines with the support of advanced analytics, machine learning and artificial intelligence accelerates the identification of issues and flushes out the root cause quickly. Once you understand the issues, remediation is faster and as a result any potential business impact is reduced.
What if you could reduce the time and effort spent on routine tasks and increase the efficiency of your operational model? And can you do so while improving your quality of service and reducing compliance risks? These are not aspirational goals but can be realistically achieved by implementing intent-based networking with centralized access control.
Advantages of intent-based networking with centralized access control
Network complexity and the rapidity of change requires a more dynamic approach to building, deploying and managing the network environment. You can overcome your network challenges today and prepare for an even more dynamic future by adding intent-based networking and centralized access to your software-defined network.
When you add it all up … Yes. intent-based networking with centralized access control is worth it.
Network transformation will call for a change in your IT operations model – new tools, processes and skills will be needed if you are to consistently gain the full benefit of your investments.
We provide a broad range of services to support your transition to an intent-based network, making it even easier to support, manage and monitor your network environment. These services include consulting advisories, maintenance and support services, management and monitoring services as well as more advanced services such as our Software-defined Lifecycle Services designed to optimize and operationalize a software-defined network.
