Editor's Notes
- #12 Now you want to build a new app. You didn’t know what app 2 was going to be when you built 1 Now, app 1 is in production. Don’t touch it! Also app 2 might be built by a totally different team of engineers!
- #18 Interface negotiation is slow and difficult Had to build all this server-side software Results were bad And you can’t re-use the backend software for other apps in your company
- #19 API Management Tools are not architected for transactional mobile use case.
- #58 Maybe add end to end data flow
