From the conception of Docker containers to the unfolding microservices revolution we see today, here is a brief history of what I like to call ‘containerology’.
In 2013, we were solidly in the monolithic application era. I had noticed that a growing amount of effort was going into deploying and configuring applications. As applications had grown in complexity and interdependency over the years, the effort to install and configure them was becoming significant. But the road did not end with a single deployment, no, the installation and configuration work was repeated over and over again, not only for each software release but for each and every environment that we promote applications to until finally being deposited into production, where this we repeat this exercise one last time.
