In the beginning...
Carnegie Mellon University pioneered early work on Cloudlets for cloud computing at the edge. Over time, various research partners gained exposure to this work and decided to participate.
In the summer of 2015, with overlapping interests in Mobile Edge Computing, a few parties joined efforts to accelerate and to leverage this research under the open source banner of Open Edge Computing (OEC).
For now OEC ecosystem includes CMU, Intel, Huawei, and Vodafone.
