Multi Tenant Data Access (MTDA) Blueprint

In the last couple of weeks alone, I read tens of articles on the subject. I found many of them proposing various type of taxonomies for cloud computing, utility computing, PaaS etc. even…

In the next couple of days I might have fun again and offer my 10 or so 2008 predictions as I did in 2007. (many of which I think are still very valid) but in case I don’t, I wanted to make sure that at least this one gets out. –       2008 will be the year of the…

No Hobbits but great chat with Lukas

When I went to New Zealand I did not manage to see any hobbits but I had the pleasure to record an ARCcast i.e. architecture podcast (direct link to podcast here) with Lukas Svoboda; not too surprisingly, we discussed Software + Services and SaaS from an Architect’s point of view.  The talk covers various aspects such as: What is…
