Hello, and welcome to the second installment of the Kubernetes state of the container world survey. At the beginning of February we sent out a survey about people’s usage of containers, and wrote about the [results from the January survey](https://kubernetes.io/blog/2016/02/state-of-container-world-january-2016). Here we are again, as before, while we try to reach a large and representative set of respondents, this survey was publicized across the social media account of myself and others on the Kubernetes team, so I expect some pro-container and Kubernetes bias in the data.We continue to try to get as large an audience as possible, and in that vein, please go and take the [March survey](https://docs.google.com/a/google.com/forms/d/1hlOEyjuN4roIbcAAUbDhs7xjNMoM8r-hqtixf6zUsp4/viewform) and share it with your friends and followers everywhere! Without further ado, the numbers...
## Containers continue to gain ground
In January, 71% of respondents were currently using containers, in February, 89% of respondents were currently using containers. The percentage of users not even considering containers also shrank from 4% in January to a surprising 0% in February. Will see if that holds consistent in March.Likewise, the usage of containers continued to march across the dev/canary/prod lifecycle. In all parts of the lifecycle, container usage increased:
- Development: 80% -\> 88%
- Test: 67% -\> 72%
- Pre production: 41% -\> 55%
- Production: 50% -\> 62%
What is striking in this is that pre-production growth continued, even as workloads were clearly transitioned into true production. Likewise the share of people considering containers for production rose from 78% in January to 82% in February. Again we’ll see if the trend continues into March.
## Container and cluster sizes
We asked some new questions in the survey too, around container and cluster sizes, and there were some interesting numbers:
How many containers are you running?
