IIoT deployments offer many benefits but also many challenges — one of the greatest being technological diversity. Even once business goals are set and parameters and metrics are agreed upon, this diversity remains an issue — on one side is a known unknown (which new technologies to trial and deploy) and the other is an unknown known (how to manage legacy technologies). The latter is particularly complex, due to diversity in the underlying technology itself, but also factors such as the original purpose of the technology, the data structure and access methods, programming languages, and protocols that may not translate well (or at all) into a modern IT setup. Unfortunately, this conundrum applies to almost all existing industrial environments, no matter their scale.
