Metcalfe's Law for IT Ops: Lowering Data Friction in Your IT Strategy

How the 'network effect' can impact your IT strategy (for good or ill)

Metcalfe's Law

Metcalfe's Law is known in popular consciousness as the "network effect" and often applied to social networks online. But the concept has been around long before the World Wide Web was born.

Back in 1980, Robert Metcalfe foresaw the value of communications networks increasing exponentially as more devices connected. The formula (n²) is used to describe how five connected devices can make 10 connections, but twelve devices can make 66 connections, for example.

At first glance, IT leaders might rejoice because it means their environments are becoming that much more valuable as new Internet-connected "things" come online or as microservices are spun up. But from an IT Operations viewpoint, this represents a vast increase in complexity.

In fact, from a complexity standpoint, it's even worse because you not only have to account for the connections to a host, but also the processes (Active Directory, CIFS, SMTP, etc.) running on the host. So it's not just n-number of hosts, but also n-number of processes running on those hosts!

Seen through the lens of Metcalfe's Law, IT complexity presents a serious problem now and in the future. This is why IT teams need to become data-driven and cannot afford to maintain the status quo. It's also why IT teams cannot afford to rely on siloed tools that are only used by technical experts, but need to adopt analytics platforms that can be accessed by multiple teams.

I've offered a way forward: Namely, that IT leaders focus on lowering the friction to data as a way of combating the harmful effects of IT complexity.
