Recently, public clouds are getting to a majority of
infrastructures. For example, using containers, Docker, Kubernetes,
Web applications, etc. Of course, public clouds are very convenient
because they are very easy to use and cheap comparing to using
physical machines. However, it's sometimes a bit boring for some
people who want to know/manage the whole of the things such as physical network,
storage, machines, etc. And also, an experience of building a tiny
cloud with physical machines could be a very good opportunity to
understand computer technologies. Moreover, it's fun for such people
like me.
I had built a my own tiny private cloud with openSUSE and OpenStack on
my own physical machines. And I'm now using it for some of purposes
such as evaluating new Linux distributions, containers, Kubernetes,
etc. I had allocated the budget around only 50k JPY (500USD) for
building it. It's quite a cheap to build a cloud system, actually.
However, it can be done with open source software and some tricks.
In this talk, attendees will get to know about the tiny private
cloud how to build, issues/challenges, benefit and the potential
capabilities of openSUSE.
