Will IversonCTO, Dev9

What’s in a Name?• Dynacron Group is now Dev9

Hi!• Dev9– Kirkland, WA software consulting firm– ~40 people, ~3.5 years– Specializing in Continuous Delivery– Open source, Java, Mobile, NoSQL

• Will Iverson– CTO. Author. Speaker. Since 1995.

Stipulations• Mobile is huge.• Mobile is multi-platform.• Secure things are [validated] on

servers.–Money, digital goods, identity, etc.

• You don’t have infinite resources.

I’m in! Let’s get mobile!

Wait…

Android Fragmentation

iOS Fragmentation

It’s even worse than that!

What exactly IS mobile,

anyways?

Touch?Small screen?

Location aware?

Considerations• Goals• People (aka resources)

• Tools• Processes

Goals• Concrete model for describing

success– Transactions?– Sales?– Reduce time to complete action?– Ongoing user engagement?

Transactions & Revenue• Give 30% to platform vendor?– Give up 50% to retail today, maybe ok– Give up 3% to CC today, maybe not

• Do you have the customer’s contact info?

Now What?• Let’s go build something!• Need a dev team… tools…

processes…

Classic ApproachNative• Use mobile platform

vendor SDK & Language

• Full device integration• Excellent CPU/GPU

performance• Hard to build

Mobile Web• Use HTML5, JavaScript

to target mobile browser

• No device integration• Slow, inferior CPU/GPU

experience• Easy to build

Hybrid Features

Hybrid Performance• Subjective vs. Objective– 10,000s of sprites, physics, more… many high

perf demos

• Requires work– Touch events, JS profiling

• Naïve implementations easy to screw up– Use mobile appropriate JS frameworks

• Perf improvements help all targets

Hybrid User Interface• Biggest

challenge• Roll your

own, or use a toolkit

KendoUI framework shown

So… why native again?• Performance?• GPU!

• Hardware integration?– Innovation!

• App Store!– Discoverability!

Additional Criteria• Testability

– Much easier to test mobile web

• Continuous Integration• Deployment Time

– Days/weeks for app store updates

• Analytics• Budget• Staff Expertise
