Why are cloud and mobileso important right now?

It all comes down to money.

• Rapid drop in computer hardware prices, rapid rise in computer hardware capabilities– Low-cost availability of server space– Low-cost availability of handheld devices

• Continual rise in cost of operating servers– Security, privacy, maintenance/upgrades– Let somebody “on the cloud” deal with it

Crashing hard drive costs

Collapsing transistor costs

Plummeting device prices

What are we really talking about?

What is the “cloud”?

• Servers on the web that you can lease for deploying software, specifically:– Secure– On-demand– Maintained

What is “mobile”?

• Any device that can be carried around– Usually small screen size– Often a touchscreen– Usually a terrible keyboard, if any– Sometimes disconnected from net– Integrated with specialized hardware• Camera, GPS, gyroscope, accelerometer, …

– (Maybe limited computing resources… for now)

So who cares?

Practical implications for youas a software engineer…

So who cares?

• Impact on overall architecture– Usually web-centric architecture (learn HTML)– Sometimes a non-SQL (non-ACID) data store– Usually built on really cheap, unreliable hardware– Ideally has platform-independent client code– Often a bit of a mess

So who cares?

• Design for performance, reliability, and other key quality attributes using…– Stateless server components– Replication– Asynchronous operations– Deferred transactions– Eventual consistency

So who cares?

• Focus on usability– Small(er) screens– Minimal text input– Usually no mouse– Often a touchscreen– Portability crucial– Maximize battery life– Ease of installation

So who cares?

• Continuous need to learn new APIs– Storing data– Manipulating data– Caching data– Accessing mobile hardware• Camera, GPS, gyroscope, accelerometer, …

– Accessing mobile services• Notifications, offline mode, video, …

• Not to mention all the new platforms!!!!

What will you do with your new skills?

• You have nearly infinite computing power…– Thanks to the cloud

• … in the palm of your hand.– Thanks to mobile.

• What will you do with your new skills to wield this power?

What will you do with your new skills?

• Your own Checki – For renting not just cars, but lots of other

equipment

• Ideas:– An app where OSU students can post listings of the

stuff that they own, search through other students' stuff, and set up rental agreements.

What will you do with your new skills?

• Your own 36Boutiques– For not just fashion shopping but also for sharing

fashion photos

• Ideas:– An app linked to local Corvallis fashion stores,

where students can post coupons and photos of themselves wearing the stuff they bought.

What will you do with your new skills?

• Your own GetMeCab– For not just getting a taxi but also for sharing rides

• Ideas:– A website where students can post a shared trip,

get a cab or other shared transit (bus maps, anyone?), and chronicle the progress of their journey (handy on a trip through Portland!)

And a billion other possibilities

• New kinds of video games• New ways to track energy usage• New methods of processing scientific data• New features for planning travel• New ways to meet people• New tools for learning useful skills• New ways to do anything that matters

Begin with the objective in mind.

• What do you want to do when you graduate?

• That should be the factor driving your participation in this course.

• And the reason to learn what we will cover.
