Ten Essential WAN Evaluation Criteria
A growing number of organizations are beginning to look beyond technical criteria when selecting a WAN solution, emphasizing additional attributes that will ensure that their WAN is designed to be outcome driven and is as agile as the business.
To ensure that the WAN has the same ability to support business initiatives as does the rest of IT, network organizations should use the following ten criteria to evaluate WAN solutions:
If the WAN link into a branch office, store or restaurant isn’t available, then many of the business functions performed at that facility come to a halt. Because of that, one evaluation criterion is that WAN solutions must be robust.
Swift and effective troubleshooting
Just as important as having a robust WAN solution is having a WAN that performs well under all conditions. To ensure high performance, the WAN solution and its service provider must have the capability of swiftly troubleshooting problems.
Rapid deployment and change management
Partially driven by the movement to implement digital business initiatives, the pace of organizational change is accelerating. In order to not impede what the business is trying to accomplish, WAN solutions must be capable of being rapidly deployed and modified.
In order to eliminate the time consuming tasks that are associated with traditional networks and hence be able to support business initiatives in a timely fashion, it must be possible for organizations to log onto a portal and have fully-featured WAN services that can be downloaded onto commodity hardware.
The security challenges that companies face will only get more challenging over time and a security strategy that is focused entirely on the perimeter of the organization is doomed to failure. As such, a WAN solution must complement a company’s existing security solutions while adding significantly to the company’s overall security posture.
In addition to providing effective security, there are a number of other ways that a WAN solution can help to mitigate business risk, such as enabling effective business continuity and disaster recovery processes. However, in order to not increase business risk, the WAN solution must not rely on scarce human resources.
While not always a requirement, there are some instances in which it’s important for the WAN solution to provide optimization functionality. One example is having optimization capabilities that enable the transmission of large files associated with a company’s business continuity and disaster recovery processes.
The skills necessary to plan, design, implement and manage a next generation WAN solution are scarce. The lack of network and security expertise within an IT organization can result in WAN solutions not being implemented and managed appropriately, putting the company and its business’s requirements at risk. It may also add to the company’s security exposure.
End-to-end user experience
A WAN solution must enable an acceptable end-to-end user experience along three key dimensions: performance, security and management. This is particularly challenging for companies that have a global footprint.
Even when faced with dramatic changes in business and technology, the importance of some evaluation criteria remain constant. One such criteria is that WAN solutions need to be cost effective.
Given the growing importance of a modern network that supports organizations’ digital transformation initiatives, it’s essential to factor in these criteria to the selection of a global WAN solution.
