re: Nicolo, It really all depends on your business and applications you are working on. Now for sysadmins for an example instead of having say some vm...
 

Thanks Joe! I was exploring the container/Docker world in the last few weeks, and I'm glad to see that your opinion sort of resonates with the one I was forming.

I'm already looking at specific cases where containers would be more efficient than the usual VM approach, like small python apps and such. But, and that's a big but, the majority of what I have to deal with are database clusters, and the ephemeral nature of containers had me thinking that would be really hard to containerise DB clusters, especially ones with sharding and replicas (take this with a grain of salt because I'm a Docker noob).

Databases in containers is a young fish. Maybe in few years where stability and speed comes up to the par but nothing will beat latency and transactions like a self/cloud hosted server. While I do run some apps and have contsinerized databases like MongoDB etc, been burned few times by simply “don’t touch it” lol.

Yeah if you can offload some of hosts/apps with containers that’s great start.
