NOTE: Please see the continued discussion in the post titled “Update on the Cloud (Ontology/Taxonomy) Model…“
Updated: 3/28/09 v1.5
There have been some excellent discussions of late regarding how to classify and explain the relationships between the many Cloud Computing models floating about.
I’m building a number of presentations for discussing Cloud Security and I’ve also been working on how to show both the the taxonomy and ontology of various Cloud components and models. I think it’s really a blind mash-up of many of the things John points to, but the others I’ve seen don’t serve my needs completely. My goal is to gain consensus on the model and the explore each layer and its security requirements and impacts on the model as a whole.
Here’s my first second third draft based on the awesome feedback I’ve received so far.
I’m not going to explain the layers/levels or groupings because I want people’s reactions and feedback to what they get from the diagram without color from me first. There will likely be things that aren’t clear enough or even inaccuracies and missing elements.
If you could kindly give me your feedback on your first (unabashed) impressions, I’d really appreciate it.
NOTE: TypePad’s comment subsystem is having problems. I’m going to close the comments until it’s resolved as the excellent (16 or so) comments are not showing up and I don’t want people adding comments using the old system… Please send me comments via email (choff @ packetfilter.com or via Twitter @beaker) in the meantime. Thanks SO much.
The comments are working again. I’ve had 30-40 comments via email/twitter, so if something you wanted to communicate isn’t addressed, fire away below in the comments!
Version 1.5 Diagram (click to expand):
In v1.5 I highlighted the Integration/Middleware layer in a separate color, removed Coghead from the PaaS offering example and made a few other cosmetic alignment changes.
In v1.4 I added the API layer above ‘Applications’ in the SaaS grouping. I split out “data, metadata and content” as three separate elements and added structured/unstructured to the right. I also separated the presentation layer into “modality and platform.” Added some examples of layers to the very right.
