Hosting
• Many options: IaaS, Containers, PaaS
• Concerns: Availability, Scalability,
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

• What is the usage policy ?
• How can I contact support, send feedback ?
• What about my data privacy ?

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
