En 2018, je m’étais amusé à prendre du recul et donner quelques statistiques sur le temps que je passe sur mon laptop avec un premier article. J’ai refait le même exercice en 2019 et évidemment j’ai pris du temps en 2020 pour comparer. Pour rappel, je partage mon temps entre différentes actions : je suis CTO à Zenika, organisateur du GDG Nantes & GDG Cloud Nantes et speaker avec le statut communautaire de GDE.

Cet article prend en compte les 6 premiers mois de 2020, toujours avec le même outil et a pour objectif de partager ce “tracking” pour échanger.

The top right quadrant from the latest Gartner cloud market analysis clearly indicates three global cloud leaders: Amazon Web Services, Microsoft Azure, Google Cloud.

How are we going to compare the communities with each other? As Karen did in his article, we will compare them by the amount of registered members or the group size in other words. It is obvious that the group size is just one metric of many, like e.g. the activity rate (how often do events take place), the average number of participants, the date of the last event and so on… The members count should serve as a simplified way of measurement of a group success or importance. …
