24. Enter API Management’s self-hosted gateway

25. What is API Management’s self-hosted gateway?
 Self-Hosted version of Azure API Management, close to their users
 It’s up to you to deploy, secure, scale, operate & manage the host
 Managed from the cloud, deployed where you need it
 Centralized management in cloud and deploy to one or more gateways
 Gateways are federated to the cloud and require internet connection
 Provides a consistent API experience in Azure, hybrid, and multi-cloud
scenarios

35. Building a platform is a journey

36. https://itnext.io/microservices-c8b5dbdd58b8
And that’s ok.

37. Start with PaaS and evolve to Kubernetes and beyond
Focus on your app, not infrastructure.

42. Are Microservices Evil?
Are Monoliths Evil?

43. Use the API landscape your platform requires,
but don’t go all the way unless you have a reason

44. API Gateway helps your platform grow

45. A special thank you to the sponsors!
