Transcript

  • 1. Web and Native Applications 4th November 2010 Stuart Scott
  • 2. Outline • Definitions: native and web • Pros and cons • Usage situations • Economics • Hybrid approaches • Positioning
  • 3. Native • Device-resident • Installed by maker/operator or user • Tool chains generally will be platform specific • Development targeted to a platform/framework – iPhone (Cocoa Touch - Obj C) – RIM (MIDP Java) – Java Mobile (MIDP / Java) – Android (Android / Java) – etc. • Developer specialism is a consideration
  • 4. Benefits of Native • Access to device features – Where supported by the SDK/platform – Sometimes these are the same • Performance – Graphics: gaming, acceleration – CPU: computation • Not necessarily needing net connectivity – Can run in offline modes • Discoverability – Some benefits in having an app already on a device
  • 5. Web Applications • Run in the browser, so limited to the browser's capability set – Which changes... • Written in web languages – Html, JavaScript, CSS – Web developers • Exploit commonality of browser – but browsers are still fragmented – WebKit: N73 → iPhone • Different type of moving target
  • 6. Benefits of Web • Fixable: maintenance server side • One size fits many • Trickery can make apps look light • Freedom – From app store reliance • Toolchain familiarity – OSX, Windows, Linux,... • Concerns, some of which are inherent to web: – Reliance on UA, where needed – XSS, Injection
  • 7. Depth of machinery Web apps Obj C Java ME Java C++ .NET Complexity Flash Speed
  • 8. APIs • OpenGL ES • Messaging • Address Book • Geo capability • Accelerometer • Compass • Trust Services
  • 9. Economics 1 • Development costs, arbitrary units – Iphone 10 – RIM 15 – Android 16 – Java Mobile 4-50 – Web 5 • Native apps need deployment mechanism – App stores • Web apps need server support – Another type of host facility...
  • 10. Economics 2 • Cost to get web application to market – Server - plus development and test • Cost to get native app to market – Platform build(s) – Store fees – Test and QA fees – SKU Management – Platform changes
  • 11. Hybrids • Blend app packaging and web app development – Attain web development with native app packaging • PhoneGap offers a stop-gap solution – Project objective: to not exist – Cross-platform Javascript/HTML deployment • Jquery html simplification – Javascript library
  • 12. Comparison What do users want? Some experience applications to consume or create Speed. Possibly. Fast access to content/information/experience Developer objective might depend on RoI and therefore means to monetise
  • 13. Success Entry costs Revenue potential – Market size and ability to address – Payout Communication – App Stores vs. known web techniques Who is paying
  • 14. Buyers (Developer perspective) B2B customers – App build, deploy, maintain B2C customers – App marketing Hierarchy – Mobile site – Measurable RoI – Transactions
