Section 2 Add data to the backend


Why do we need a backend?

!26


Can I just reuse my existing backend? Maybe.

!27


Gotcha #1 No server-side page generation!

!28


Gotcha #2 Most differentiating features (geoloc, push notifications, etc.) require dedicated servers, code, and infrastructure.

!29


We’re going to use a BaaS today! !

Efficiently addresses Gotchas 1 & 2 + doesn’t require code

!30


It’s like a database that you call directly from your client code.

!31


It’s a cloud service that makes it easy to store your data, retrieve it & query it.

!32


It’s like iCloud or Skydrive to synchronize all your app data across users and devices

!33


Even in BaaS, there are plenty of alternatives!

!34
