AWS, particularly Lambda, step functions and budgets. The business is a marketplace addon. Lambda functions handle the webhooks to add, upgrade or remove the addon. Step functions handle guiding new users through onboarding, by sending email reminders automatically re-configuring the service based on customer actions. Budgets make sure a customer is not using more resources than they are paying for, and send email alerts to me and customers at various usage amounts. I have extracted a lot of my AWS and Lambda software into an open source boilerplate app: https://github.com/nzoschke/gofaas https://github.com/nzoschke/gofaas It's amazing how little code and operations this business requires!
