For time on when we will finish our credit on Azure platform, where we will putt our ARNEIS project's assets?

I would suggest to use https://github.com/B-AROL-O/ARNEIS/issues/171 and discuss there in detail the use cases, such as:

• who should have the right to write the asset(s)
• who should have the right to read the asset(s)
• for how long the data should be stored
• how much are we going to pay (I mean, after the MS Azure grant provided by OpenCV expires)
• etc.
