surviving the awkward adolescence of a microservices-based application

Description

Scott Triglia - Arrested Development - surviving the awkward adolescence of a microservices-based application [EuroPython 2015] [24 July 2015] [Bilbao, Euskadi, Spain]

The potential upside of microservices is significant and exciting. So much so that Yelp's Transaction Platform committed from the start to an architecture of small, cooperative microservices. This talk explores the inevitable complications that arise for Python developers in as the services grow larger and stretch both their own architecture and the developers responsible for them. Come hear tales of terror (tight coupling! low test coverage!), stories which will warm your heart (agility! strong interfaces!), and everything in between as we follow the adventures of our plucky team.

The talk will be focused on the functional, cultural, and reliability challenges which occur as a microservices-based project evolves and expands over time. Particular attention will be paid to where these diverge from the utopian way microservices are often described, and to the particular difficulties faced by Python developers trying to implement such systems. My goal is to share with attendees some mistakes we've made, some successful methods for growing gracefully, and Python-specific tools/libraries which can help with these problems.

To enjoy this talk, you should be aware of the basic vocabulary and concepts of HTTP-based services. Any additional awareness of distributed systems (and their failure modes) will be helpful.
