Hi all,
Attached is the PDF containing the slides used at Phreaknic19 Future of
Linux session last night to talk about containers and clouds. There was
a lot of good discussion around containers and security - could be an
interesting future NLUG presentation?
I enjoyed the panel with Dagmar and Howard, and thanks to Ben Hicks for
setting everything up!

Wesley didn't see Michael Chaney's presentation about Jailed servers
running in BSD many ages ago. We have discussed these precursors to
containers and their operations advantages to other virtual style
implementations. Now, I bring up this point not to discourage the topic
as containers have come a long way since those jailed systems came to
practice. Yes, the point Wesley made in his presentation about the
impact of containers versus virtual guests is important. How many
layers, how many copies of what has to be maintained and supported.
Some of us, okay I, wince at the thought of having an operating system
running to support having an operating system to support a java or
erlang virtual environment.
The slides can't reflect Dagmar's comments on the practical effects of
the production environment. My experience with "update constipation"
completely echoes what Dagmar reports - nobody wants to touch anything
for fear it might break (and that "they" might have to fix). This is
the way we manage our highways - we wait until the bridges fall down and
then slap dash a fix. Okay, off the soap box.
