In this short article we’ll overview and briefly compare regional communities behind the three major public cloud providers: Amazon Web Services (aka AWS), Microsoft Azure and Google Cloud. The overview only covers three predominantly German-speaking countries: Germany, Austria and Switzerland (also called “DACH” countries).

The top right quadrant from the latest Gartner cloud market analysis clearly indicates three global cloud leaders: Amazon Web Services, Microsoft Azure, Google Cloud.</div>What criteria are we going to use in comparing the communities? We will make the comparison based on the number of registered members, i.e., the group size. It is obvious that the group size is just one of the many metrics, such as the activity rate (how often the meetups take place), the average number of participants, the date of the latest activity, etc. The number of members should serve a simplified way of measuring a group success or importance.

The internet is big. What types of groups are we going to count? Indeed, there are cloud communities organized in Facebook groups, on various messenger networks like Telegram, independently hosted forums, etc. In this research, we will count only communities hosted on the platform. Currently, Meetup is, in fact, the most popular community platform in those 3 countries.

We will only consider somehow active groups. It means that a group should have at least one registered past or upcoming event. In the locations where multiple communities dedicated to the same cloud technology are present, only the biggest one will be considered. For example, Munich has two Azure groups – one with 1581 members and the other with 641 members. Let’s only take the biggest group, instead of summing up their numbers, since there is a high probability of members overlapping between those groups.

The article gives only a snapshot of the situation as of April 11, 2020. The author doesn’t intend to make updates reflecting changes. It’s a photo rather, than a video.


Germany has a population of over 83 million people. It is one of the most important technological hubs of Europe. Plenty of universities, industrial and service companies belong to the landscape of most of the cities in this country. Even small places might have lively user groups here.

As we can clearly see from the table, both AWS and Azure have broad community networks covering most of the populated cities and towns in Germany. Azure communities having the biggest number of groups demonstrate a tendency of going into the long tail by covering smaller locations, where AWS groups are not present at all. Google Cloud groups (aka “GDG Cloud” chapters) have the weakest cloud community network in Germany. However, one should not forget the much wider network of general Google Developer Groups (abbreviated “GDG”), which also occasionally run Google Cloud themed meetups. Also, Google Cloud is the youngest offering of the three clouds.

There are some large cities in the country, like Essen, Bremen, Bochum and several others, where none of the three cloud players have community footprints. These are opportunities for the future growth.


Austria has a population of almost 9 million people. Unfortunately, the presence of cloud related groups is not very impressive here.

Graz 289440      
Linz 204846 218

The two blank spots are the cities of Graz and Salzburg. While Salzburg is mainly a touristic site, unlikely to attract a lot of cloud enthusiasts, the city of Graz is a completely different story. It’s a pity it doesn’t have a community footprint of either of the big clouds.


Switzerland, with the population of over 8 million people, is the smallest of the three predominantly German-speaking countries. Despite this, it has technologically advanced population in its cities, backed up by universities and subsidiaries of many tech companies. Thus, Swiss cloud groups seem to be better presented than those in Austria.

The city of Lausanne doesn’t host any of the cloud communities. A Google Cloud group exists only in Zurich, its European headquarters.

IBM Cloud has a community network at least in Germany: being even smaller than the Google Cloud’s network, it has been ignored in this report. Oracle Cloud is another rising cloud provider, which doesn’t seem to have a clear community strategy and, as a result, has almost negligible following among local developers. This is clearly a drawback, which should be corrected to match the high ambitions of this corporation on the cloud market.

Update from 18-April-2020: To be precise, the GDG Cloud group that is listed in the report under the city of Frankfurt is in fact located in the neighboring city of Wiesbaden (population: 278,342). Also, most of the group’s past events were held in Wiesbaden. Thus, Google Cloud has a local community in Wiesbaden, but doesn’t have one in Frankfurt.
