Topics to cover
• Downside of directly exposing your API
• Introducing Proxy’s & Gateways
• Features you need to know about
• Available tools
• Azure API Management
Downside of direct access
• Flexibility in deployment story
• Versioning is harder, and in code
• Security, Authentication, Authorization in code
• Cohesive API forces single solution (mega code base)• Not micro-service friendly
• Basically, you need it? You write it!

Plug the API into the manager
Take advantage of the magic: operations
• Adding operations enables built in tools
“Products”
• You have to add your API to your products
Now subscribe to the Product
• Users have to subscribe to products, to get access to API’s• Administrators are auto subscribed
Developer Portal
• We can test our api from the developer portal
• Upper right of admin panel
Developer Portal
Code Generation
Console for testing
