We want to monitor which Wikibases are on cloud and how large they are in relation to each other, so that we can have a better understanding of how our users are using Wikibase Cloud, the health of the ecosystem and what future requirements related to scaling might be.

AC:

• Platform Summary dashboard contains a visualisation of the Wikibases on cloud with relative size to each other
• Size is defined as amount of entities
• The Wikibases (the url: name.wikibase.cloud) should be visible (hoover-over is fine)
• We should be able to analyze trends over time, a weekly refresh of the data is sufficient
