Castle On A Cloud: The Github Story

on YouTube ↗29m

" summary

GitHub runs most internal apps across roughly 350 AWS instances and about 250 Heroku dynos and balances EC2, RDS, EBS and S3 with concrete tooling: IAM roles plus STS and instance profiles for per‑env credentials, VPCs with Direct Connect to the colo, resource tagging for cost reporting, and a Campfire+Hubot driven chat ops surface that can provision or terminate servers. The urgent problem is S3 bucket limits solved by consolidating environments into single buckets with prefixes and cross‑account write‑only dropboxes.
