Edge computing is one of those confusing terms, much like cloud computing. Where there is a factorial of 50 kinds of cloud solutions, there is a factorial of 100 edge solutions or architectural patterns that exist today. This article does a better job of describing the types of edge computing solutions that are out there, saving me from relisting them here.
It’s safe to say that there are all types of compute and data storage deployments that qualify as edge computing solutions these days. I’ve even noticed vendors “edge washing” their technology, promoting it to “work at the edge.” If you think about it, all mobile phones, PCs, and even your smart TV could now be considered edge computing devices.
