Couple of weeks ago I posted about Zermatt and how Security Token Services and Claim Based authorization can help in the Identity Management area.
Sebastian who has been working with Zermatt for a couple of weeks already, is posting a useful “straight to the point” how to implement active and passive STS’s using Zermatt. The abstractions in Zermatt are making this a joy. I like the separation of the STS from the underlying host (i.e. ASP.NET, WCF, “put-the-name-of-the-next-foundation”) because allows you to reuse the same STS for both the service layer and the presentation layer and have a consistent access control mechanism on both layers using claims.
Also, while we are on the subject, I recommend you to read the latest Architecture Journal on Identity. I just read Vittorio’s article and it has all the things you need to know about the underlying concepts.
Cloud Computing Taxonomy Map
August 19th, 2008
Lately the term SaaS became a broader term and now it is called Cloud Computing (see David Chappell’s paper and Wikipedia). It includes the whole paradigm of utility computing + saas + platform as a service + * as a service.
I’ve got good feedback on the taxonomy map from the blogsphere (including Jeff Kaplan, from THINK IT Services). I updated the map some time ago but didn’t have time to publish. So here it is rather sooner than later. (I need Pablo’s help to do the animated GIF, so this time is static)
