Silicon Chalet Divio Demo App

This is a simple nginx server with an index.html saying hello and showing the number (and type) of services currently attached.

It was used for a demo during my presentation at Silicon Chalet on the 19th of September:

I migrated 7,000 applications from PostgreSQL 13 to 15 by Lucy Linder (Divio Technologies AB)

Ever wondered how a small team can migrate 7,000 PostgreSQL databases in just two months without disrupting service? Join me as I share how Divio pulled this off! I'll brush on strategies that made it possible, the challenges we faced, and the extra lengths we went to keep our users' peace of mind unscathed.

You will find the slides of the presentation and a recording of this demo on this repository, in the other folder:
