1000 users, almost 0 request per second / 10000 euro a month to deploy a very simple software on GKE in 3 continents and have some development instances. Why? Because Docker and "scalability" it offered looked much better on the investor slides... How? Instead of actually hiring someone that at least has experience with docker he decided it was very easy thing to learn so he did it him self and we ended up with thing like running two application in a same container, having database on containers that disappear (container restarts when ram is full is the best way to run a database) etc... And after all that started talking about mirco-services and how cool are they for code decoupling... Of all the things... I don't work there anymore... And if challenged on these reasons some people give (that supposedly have more experience) blanket statements like: "Docker is more safe by default thus we should use it..." Maybe when you go thought these situations you get to write articles like this. Of course containers, docker, k8 etc have their place, but in reality you can find all kinds of stunning non-sense.
