Roleypoly Infrastructure

Ring 0

Any of these missing is a service outage.

Backend

Backend is a Cloudflare Worker deployment. Edge computing, fuck yeah!

Hosts:

  • api-${env}.roleypoly.com/*
    • ex. for stage: api-stage.roleypoly.com/*
  • api.roleypoly.com/* (only in prod)

It uses 3 KV namespaces per environment:

  • Sessions

    • Store of data and tokens mapped to sessions
    • All data subject to 6 hour TTL

  • GuildData

    • Store of guild data, e.g. categories, etc
    • All data is permanent (maybe doubly persisted to Firestore)

  • Guilds

    • Cache of Discord guild + guild member data
    • All data subject to a 5 minute TTL

App UI

The Next.js server is a docker container hosted on Google Cloud Run in multiple regions with a load balancer. Region focuses knowing traffic: US (x3), EU (x2), AP (x3). There is a running maximum of 10 containers per region, and a minimum of 0.

Regions:

  • us-east4 (South Carolina)
  • us-central1 (Iowa)
  • us-west1 (Oregon)
  • europe-west2 (London)
  • europe-west3 (Frankfurt)
  • australia-southeast1 (Sydney)
  • asia-northeast1 (Tokyo)
  • asia-southeast1 (Singapore)

Staging is only deployed to us-east4.

Hosts:

  • web-${env}.roleypoly.com
    • ex. for stage: web-stage.roleypoly.com
  • roleypoly.com (only in prod, after release)
  • next.roleypoly.com (only in prod, pre-release)
  • beta.roleypoly.com (only in stage)

Ring 1

Ephemeral services that can be tolerably lost, and would not be considered an outage, only degraded.

v1 Migration Service

Hosted on v1 infrastructure, e.g. DigitalOcean. It is a connector and JSON API to the old v1 PgSQL data.

Host: migration.v1.roleypoly.com (Locked down to specific authorization tokens)

Sunset: Roleypoly Next + 3 months

Bot (Mention Responder)

Bot doesn't do much, it's on a modestly sized Compute Engine VM using container hosting. It has no access to anything related to the real deployment of Roleypoly :)

Region: us-east4 (South Carolina)

Ring 2

Not end user applications. These will never be considered an "outage" if they are lost.

Design System Storybook

Design system is a Vercel deployment

Host: ui.roleypoly.com
