Development Notes

TODO

• Customize SaaS design
• Customize SaaS pricing
• Customize SaaS features
• Customize SaaS readme
• Simplify main readme to show usage
  • Move self-hosting info into a separate doc
• Add use cases section
• Create blog post

Alternative Architecture

• API
  • Creates and manages CronJobs
  • Hosted on ZEIT now or Google Cloud Functions
• Scheduler
  • Creates CronJobRuns from CronJobs based on their schedules
  • Hosted anywhere?
  • How to scale scheduling horizontally?
    • Post-MVP; also may not be necessary given the Runner is doing the real work
    • Easiest solution would be static N servers and round-robin
• Runner
  • Executes CronJobRuns taking them from pending => success or failure
  • Triggered by the creation of CronJobRuns in Cloud Firestore
  • Implemented via Google Cloud Functions
• SaaS
  • Bundles this cron API into a SaaS product via Saasify
