20k mRuby devices in Production

One of the biggest cases of mruby in world. I've changed an entire solid runtime for mRuby, and for 3 years, even if is not recommend, we've been running mRuby in production reaching 20k machines and billons of dollars in payment transactions. We faced a lot of problems, but even more benefits adopting mRuby. This talk is about those topics, like:

Runtime and application Update/Upgrade
Communication configuration and intelligence
Payment transaction security and cryptography
Concurrency
Code sharing between CRuby and mRuby
Memory management and leaks
Open Source
