I’ve mentioned the agile and personal cloud in previous posts, and, like most architectural / patterny folks, I’ve started thinking about the cloud in layers (whatever the proper meteorological term for cloud layering is — it may really just be “cloud layers“). They are:

1. The Personal Cloud
2. The Services Cloud
3. The Platform Cloud
4. The Agile Cloud

I need to think a bit more about how to draw that layered picture — and your help is certainly welcome — but I think they do build on each other and have some inter-relationships as well. I will write more about the two middle clouds soon, but in the meantime the folks over at Perficient have posted the presentations from their cloud event a few weeks ago. You can check them out here.
