SWIPE CONFERENCE 2012

• Needs when choosing a backend

• Features

• Overview of different approaches

Outline



Who am I?



UX designer and developer



Who are you?



Quick version



It’s complicated



Thank you!



• Not apps where mobile is “just a view”

• Apps which are inherently mobile

• From web to app

• App needs a back-end

App Target



Examples



dayoneapp.com



culturedcode.com/things



Questions



Have I to manage it?



• At which level?

• Am I able to do it?

• Have I time to learn?

• Is it worth it?




What’s the synch model?



• Does it match my goals?

• Can I change it if needed?

•What about protocols?




Have I to pay?



Who is to pay?



Impact on UX?



• Does it break any flow?

• How frequently?

• is it “ok” with that?

Impact on UX?



Lock-in?



• How to migrate data?

• Switching cost?

• Effort

• Code front-end

• Data compatibility

• Cash

Lock-in?



• iCloud

• Dropbox

• Custom

• Back-end as a Service (BaaS)

Options

It just works ...



... when it works.



• Have I to manage it?

•What’s the synch model?

•Who’s to pay?

• Impact on UX?

• Lock-in?

Questions



• Learn the API

• Apple takes care of

• installation

•Monitors changes

•Works on metadata

• Shreds files

• Supports conflict resolution

Daemon



Special folder, synched



Synched when “appropriate”



• Key-value

• Documents

• CoreData

Types of Information



• The final user

• Your app will use his quota

• 5Gb for free

Who’s to pay?



Impact on UX?



• User expectation

• No control on upload

• “Why isn’t there?”

• Open the app to synch

• User turns off iCloud?

Impact on UX?



Lock-in• Huge

• Only on iOS

• No way to migrate



Dropbox



• File-based

• Special folder

• Synchronized across devices

• Supports other platforms

Dropbox



• Already set up

• installation

• bandwidth

• scalability




• Desktop synchronizes continuously

•Mobile apps have to query the backend

• HTTP API

• SDKs for iOS, Android, Ruby, Python




• No conflict resolution (revision #)

• Data serialization is up to you

• No file shredding




• The final user

• Your app will use his disk quota

• 2 Gb for free

Who’s to pay?



• Authentication the first time

• User might modify files

• Control on the upload

Impact on UX?



Lock-in• None

• Each user owns his data

• Personal/team usage

• ... but nothing more



• box.net

• sugarsync.com

• google drive

• amazon S3
