Monolith-ifying perfectly good microservices

on YouTube ↗26m

" summary

Intercom reimplements standalone services back into a single Ruby on Rails monolith and reports clear wins: moved webhooks from Java into Rails, 2.5 million lines of Rails with 60% tests, runs ~100k processes and about 150k web requests/sec at peak, deploys every five minutes, and runs 100k tests in under five minutes. Tools used include AWS, Aurora, DynamoDB, Honeycomb, SQS and dependabot; outcomes are better observability, simpler ops, easier team rotation and successful longterm stability.
