I used to manage a dozen VPS since many years: Zabbix, Gitlab/Gitlab CI, private docker registry, production environment (3 nodes docker swarm cluster), database server (MariaDB & MongoDB), blog server (running Ghost), logs collector (Graylog), etc… I was spending a consequent amount of money & time for all these VPS, and it was time to change.

I wanted to write a quick off-topic article about the ongoing coronavirus pandemia since there’s a lof of false opinions and fake news on this topic. This virus (SARS-CoV-2) is deadly and not really comparable to the flu, it is at least much more contagious. (We don’t know anything about the death rate yet, since the pandemia is ongoing). You shouldn’t treat it lightly. Not staying home will cause a lot of deaths in the months to come because of the overwhelming of your country healthcare system.
