I'm familiar with the cell architecture promoted by the WSO2 papers (and other resources). I like it and I've used it in client projects.
However, this article uses "cell" in a completely different way. It is not the cell-based architecture that you are promoting here without reading the article.
In the CBA paper, a 'Cell' is an architecture construct you can use in the design stage and take through the development and then to the deployment. So, it addresses both application and deployment architecture. Each cell has a boundary, a cell gateway, and components inside the cell.
Thanks for the follow-up and I apologize for my snark. It appears my knowledge was out-of-date and I stand corrected. I'll need to brush up on the current docs and research.
