Skyscanner Hotels is built on top of Aiohttp and has been chosen as one of the formally supported frameworks by the company. This talk will tackle how Aiohttp is used, what we have learned and how we are trying to generalize some implementations and patterns to be used by all micro services from scratch at Skyscanner. The talk will cover also essential stuff related with Asyncio, HTTP protocol, and the AWS infrastructure. All of them are essential to understanding some of the points that will appear during the talk.
