> When I was researching about this a few years ago I read some really long in-depth scathing posts about Open stack. One of them explicitly called it a childish set of glued together python scripts that fall apart very quickly when you get off the happy path.
And according to every ex-Amazoner I've ment: the core of AWS is a bunch of Perl scripts glued together
I think you know as well as I do that it very much does matter. Even if you have an army of engineers around to fix things when they break, things still break.
I think the point is that for Amazon it's their own code and they pay full time staff to be familiar with the codebase, make improvements, and fix bugs. OpenStack is a product. The people deploying it are expected to be knowledgeable about it as users / "system integrators" but not developers. So when the abstraction leaks, and for OpenStack the pipe has all but burst, it becomes a mess. It's not expected that they'll be digging around in the internals and have 5 other projects to work on.
