Indeed Vedrin has pointed earlier to issue 3), which I should have already fixed. > To summarize, an improved version of OpenTox AA (with the newest OpenAM and > policies extracted from the current setup and imported into the new one) can > be setup in few days, and will have a better response time and scalability > than currently.

We can probably best discuss in the meeting, where and when to set up the new service. I am not a fanatic about cloud vs standard deployments, but would generally prefer a cloud-based solution, mainly for reasons of easier manageability. Let me just point at an advertised difference between Jiffybox and most cloud services, which is the dedicated resources (in German: https://www.jiffybox.de/faq_index.html). I have experienced very good performance with JB so far. Best regards Andreas
