Have you ever wondered what those "Nanami Madobe and Claudia will be able to solve the problems in the Akihabara store?" shorts are from? Well, they seem to have originated from an online Microsoft Azure training course by Microsoft itself: http://web.archive.org/web/20141026212607/http://www.microsoftvirtualacademy.com/training-courses/claudia-azure

The series is self is officially called "Ao no Butai ni Omoi wo Yosete" (or 「碧の舞台に思いを寄せて」 in more traditional Japanese). Microsoft actually made quite a few of these types of shorts in Japan (such as https://web.archive.org/web/20150425041112/http://www.microsoftvirtualacademy.com/training-courses/claudia) and even some mangas (such as those in archives of https://web.archive.org/web/20121116074845/http://msdn.microsoft.com/ja-jp/windowsazure/gg194745).

UPDATE: I found the shorts available in higher quality on the Russian video-sharing site VK Video: https://vkvideo.ru/video-215715880_456239455
