Security, Rate Limitation
• Pricing balance: who’s willing to pay for
the bot, and how much
• Heroku PaaS Free Dynos
• AWS/Google/Microsoft free plans
• Currently testing Serverless Functions

Serverless is great
• no deployment hurdles, scalability from day 1
… but
• tedious dev cycles (commit, push, test)
• painful to diagnose (read logs through)
 local emulators to the rescue
 run and debug locally
 integrate in a CI/CD tool chain
Lessons learnt
