A Brief About Technologies

Technology is changing so fast that it is very hard, if not impossible to follow. The moment we learn about a new technology, it is already obsolete and replaced with something else.

Take containers as an example. Docker appeared only a few years ago, and everyone is already using it for a myriad of scenarios. Still, even though it is a very young product, it changed many times over. Just when we learned how to use docker run, we were told that it is obsolete and should be replaced with docker-compose up. We started converting all our docker run commands into Compose YAML format.

The moment we finished the conversion, we learned that containers should not be run directly. We should use a container scheduler instead. To make things more complicated, we had to make a selection between Mesos and Marathon, Docker Swarm, or Kubernetes.
