As such, not only did I join a company that promotes multi clouds and hybrid clouds, but a part of my job is also to prove the better economical and performance dominance of private clouds over public clouds.
And yet, it seemed a bit hypocritical of my part to keep most of my stacks on public clouds. Moreover, since I am now in charge of procuring servers for our infrastructure, I might as well acquire one of those for myself and have fun with it ! Well, most probably one of the great grand fathers of the kind we get at Canonical, but still ;-D ). **Finally, it might be fun to prove that you can compete with public cloud prices even with modest/commodity hardware, since Canonical and its clients already do with larger infrastructures.**
