  • Client -- javascript client library that runs in web browser
  • Load balancer/ssl -- HAproxy
  • Database -- PostgreSQL
  • Compute -- VM's running TCP servers (e.g., sage, console, projects, python3, R, etc.)
  • Hub -- written in Node.js; primus server; connects with everything -- compute servers, database, other hubs, and clients.
  • Storage -- Snapshots of project data
  • HTTP server -- Nginx
