Your Legacy Network Management Tools Just May Fail You


The most successful digital transformation initiatives today center on 50/50 partnerships between the business and IT. Enterprises are developing new and rapidly evolving business models, and IT organizations are stepping up to support these models with new technologies, such as the cloud, software-defined networks, and the Internet of Things.

In order to implement these new technologies, IT teams are adding complexity to their infrastructures, making them larger and more difficult to manage. The tools they’ve been using to manage their digital infrastructures were suitable for smaller, more static environments, but are not able to handle today’s growing needs.

Enter the legacy tool problem. Legacy tools often can’t adapt and support evolving digital infrastructures, leaving IT teams struggling with visibility gaps and an incomplete picture of what’s happening within their systems.

Shamus McGillicuddy, Senior Analyst, Network Management practice for Enterprise Management Associates (EMA), explores these issues in a new whitepaper, “Digital Transformation: Will Your Legacy Tools Fail You?”

One of the biggest issues legacy tool users face is scale. Their legacy tools support a fixed maximum of devices, interfaces, and other managed objects in the network. Unfortunately for users of such tools, most networks are growing. The number of devices connecting to the network is swelling, and the number of applications traversing the network is exploding. Many organizations are also expanding the number of remote sites connected to their wide-area networks.

This was the case with one tier 1 Communications Service Provider whose incumbent legacy tool provider couldn’t support the 135 million data points -- and growing -- it needed to collect and understand. The CSP therefore lacked visibility and polling fidelity and was left with excessive operational costs that prevented ability to scale.

However, when the CSP moved away from its legacy tool, it experienced a ten-fold increase in infrastructure coverage with a 75 percent reduction in operating expenses. This proves the need for a digital infrastructure management tool that has the capabilities to scale with a growing infrastructure.

McGillicuddy covers the need IT’s need for scale in more depth, as well as the issues of tool fragmentation, demand for agility, and trustworthiness of data in our latest whitepaper.
