This might be a bit ignorant question, but why everyone is saying [1,2,...] that Flask and/or Bottle HTTP servers are not to be used in production?
Seems like things have changed a lot, for example bottle+ssl+gevent sounds like a viable option for production (to me) which handles the main concerns:
Am I missing something, like a major security risk? or a performance issue? I mean how much faster might nginx or apache2 be when the major bottleneck is IO?
(Side-question: what you suggest for micro-service deployment with minimal system requirements?)
Cheers
The short answer is that default server is slow and not concurrent. You asked whats wrong with bottle+gevent (leaving aside ssl for now), I don't see anything wrong but it is not the default server :)
for small deployment your option seems reasonable but when it will grow bigger and more complex nginx will be a more simple tool to manage since it will separate your concerns (static vs dynamic routing & ssl).
Nginx for example have a much more robust and variable options on ssl handling then the more native approach
But as I said, If you are doing a small setup, keep it simple :)
