2. Why we created a
Backend as a Service
• We are a Team of Backend-Devs,
Frontend-Devs and ProjectManagers
• We have developed several apps
• Backend has always been „pain in the
ass“ that no one is willing to pay
• so we decided to make things easier

19. BaaS -
Myth With choosing a BaaS-Provider...
...I will be locked in his system
No. You own the data. You can export it.
...I won‘t be flexible enough
No. You can inject custom backend logic.
... I cannot connect to my existing data
No. You can import/connect your data.
... my Data will be somewhere on the world
No. apiOmat is completely hosted in Germany.

22. CityKit
• Adresses, Offers, Coupons,
Appointments around the user
• 30 Data Model Classes, csv import
• Native iOS & Android App
• PHP-Website, GWT-Dashboard
• only 2 month for planning and
implementing backend and iOS-App
Donnerstag, 7. März 13
23. Generic vs. generated
SDK
• if we would have used a generic sdk
we would have implemented 30 data
models 4 times
• we edited the data models on the
website --> 120 classes in the sdks
were generated automatically
