- 23. @cmaneu Measure things early Not implementing the audio preview made the key metric for this feature grow by ~200% https://aka.ms/fast/insights
- 26. @cmaneu Which service you’ll not build yourself? • Exceptions Telemtry • Logging • Email gateway • SMS / Push notifications gateway • Payment processing • User management • CD/CI agents • DNS Servers • Search • Content moderation • Personalization (if not core business) • SSH Bastions • In-App Chat

- 28. @cmaneu Use “off-the-shelf” APIs and services When a document is uploaded, categorize it If it’s a picture of someone, check quality If we already have a picture on another document, check if it’s the same person If it’s an official document, get specific fields values for the database When all documents have been uploaded, send a confirmation email

- 33. @cmaneu No UI • Reduce the amount of UI needed • Try to see if you can have an email-based / chat-based / etc.. UI • AMP-project can help you create interactive emails https://amp.dev/documentati on/examples/?format=email https://docs.microsoft.com/en -us/outlook/actionable- messages/index
- 34. @cmaneu No UI
- 36. @cmaneu No account management – JWT tokens
- 37. @cmaneu Recipes for account management • JWT Tokens • JWT Tokens + Revocation • Outsource user management (Azure AD B2C) • Roll you own user management
- 38. @cmaneu Widen your definition of “Databases” • CSV and simple storage FTW • Table storage • Document storage • NoSQL Databases (MongoDB, …) • Excel files on a storage / share
- 40. @cmaneu Use an API Gateway
- 41. @cmaneu Use scientist libraries public bool CanAccess(IUser user) { return Scientist.Science<bool>("widget-permissions", experiment => { experiment.Use(() => IsCollaborator(user)); // old way experiment.Try(() => HasAccess(user)); // new way }); // returns the control value }
- 42. @cmaneu Automate all the things Infrastructure, Code deployment, … Azure ARM template Terraform template GitHub Actions
- 43. @cmaneu Rethink your product Map a customer journey Do things that don’t scale Measure early Technical shortcurts Use & abuse existing APIs Find ways to remove UI Widen your definition of databases Prepare for next round Use an API Gateway Use scientist libraries and features flags to refactor Automate early
