The implementation of a Software-defined Infrastructure 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 a Software-defined Infrastructure. These additional capabilities translate a business-aligned policy into a desired network state by using centralized network orchestration software to automatically implement policy-based configurations consistently across the network. IBN develops customized networking baselines to define the optimal network state. 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 increasing complex driven by digital transformation initiatives, more cloud-based applications, a proliferation of a broad diversity of end-point devices, and a demand for an ever-increasing level of service to remain competitive. And yet, McKinsey has 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 and
  • 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, you will take some of the strain from your IT team, mitigate risk and gain the benefits of 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 while gaining improved quality of service and reducing compliance risk? 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 challenging future by adding intent-based networking and centralized access to your software-defined network.  

When you add it all up – Yes.  It’s 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…
