Containers are finally making their way into the real world. According to a survey out this week from Nginx, 20 percent of respondents say they use containers in production, and one-third of the respondents run containers for more than 80 percent of workloads. Both developments are huge.
I see this in my world as well, as large enterprises now do real work with Docker and CoreOS.
On the surface, the objective is portability. Containers let you move from cloud to cloud with little or no modifications. However, the chances are low that a Global 2000 IT shop will move from Cloud A to Cloud B anytime soon.
