2 Introduction Mobile is disruptive WebRTC is disruptive This session discusses the importance of WebRTC in the mobile environment and what to consider when developing with WebRTC in your application. Apple Android 1

3 Be Mobile First Enterprise use of mobile technology is growing at 25% per year But most critical decisions still require a desktop computer Creating opportunity to reinvent the nature of work The average adult has 24 apps on their phone But spends 80% of their time on just 5 of them Raising the stakes for real time relevant engagement The number of custom mobile apps will double compared to 2014 But 85% of companies have a mobile backlog of up to 20 apps The average person has their mobile devices within arms reach 90% of the time But at any given time malicious code is infecting more than 11.6 million of them Making speed and agility more critical than ever Making security as important as convenience 2

4 Real-Time, Contextual Communication in apps Systems of Interactions Mobile Audio/Video can be hard. WebRTC can make it easy. Contextless Communication using Individual applications User experience is key. In app real time communications can enhance and simplify this experience through context. Contextual Communication with embedded WebRTC 3

5 Consider a Use Case: Healthcare App The app knows all about Sue She has a Talk to Physician s Assistant(PA) button so he clicks it. She s placed in a Queue and a call is established with the first available PA Sue is sick and launches her Healthcare app to book an appointment. Bob(the PA) takes the call and helps Sue. They decide she doesn t need to see a Doctor and will be OK. 4

6 Getting WebRTC on Mobile Platforms WebRTC is available to be built natively There are cordova plugins that provide WebRTC (ex. cordova.plugins.iosrtc) No native browsers for mobile web*, though you can build your own or use Ericsson s Bowser Browser. WebRTC is available to be built natively WebView provides access to WebRTC for Hybrid apps Android Chrome provides WebRTC for mobile web Getting WebRTC on mobile is not too hard, but there are challenges to consider: Signaling for WebRTC Security Multi-platform development * Apple is slowly adding things: Apple implements features of GetUserMedia and MediaStreams in the mac ports of webkits(aug. 15th, 2015) 5

7 Signaling WebRTC does not provide a signaling standard Provides means to connect two (or more) parties/services Peer to Peer Connection Challenges Choosing a library vs. creating your own Pub/sub vs. Sip over WebSockets Web and Mobile portability Hybrid vs. Native networking Sleeping devices and power consumption Identifying available peers and services WebRTC Island vs. Federation 6

8 Security Authentication Authorization Identity verification Encrypted Signaling App authenticity (did you download the correct app and is it secure) Challenges: Enterprise Security Integration (LTPA, OAuth) Access Control Lists and Identity Propagation Need Mobile SDK/App Store Authority Note: Browsers are moving to https only (no getusermedia requests) 7

9 Multi-platform development Developing for omni-channel Native (ios/android), Hybrid and Web Hybrid JavaScript frameworks Challenges Native Multiple codebases (UI and Signaling) Building Native WebRTC OpenSource Development Resources with native skills Hybrid Framework selection Performance ios WebRTC plugin support Testing Automation due to lack of WebRTC support in emulators Future proofing your SDK decision 8

10 Hybrid Development Hybrid frameworks like Apache Cordova and React Native provide OS abstraction and allow developers to code in HTML5/JavaScript Apache Cordova(formerly PhoneGap) provides native functionality via Plugins that expose a JavaScript API (Cordova has ~580 plugins) Single Page Applications are recommended (Can use any library like AngularJS, EmberJS, Backbone, ReactJS, jquery Mobile, etc ) WebRTC functionality is provided by a plugin: cordova.plugins.iosrtc HTML5/JavaScript in WebView Your Hybrid Application cordova.js & plugin JavaScript APIs Cordova Native Code & Native Plugin Code Native OS React Native enables developers to use JavaScript and React. For additional native functionality, you must provide it yourself. WebRTC plugin can be built from webrtchacks.com 9

11 Hybrid Development JavaScript mobile frameworks The quickest route with hybrid mobile is through a JavaScript framework. Some very different ones to consider are: Ionic is implemented on top of angular.js and uses cordova. WebRTC is provided via cordova.plugins.iosrtc. React Native Mobile environment using JavaScript and React. Build your own React Native WebRTC plugin from webrtchacks.com These provide a consistent UI look and feel as well as 3 rd party plugins and modules to enable extended functionality. React Native is React specific 10

12 Mobile apps go deeper than front-end UI Front-end Back-end User engagement Short time to market Web? Hybrid? Native? Teamwork Industrialize app dev Integrate with SDLC Operations 30% of the value and effort is visible (mobile UI) 70% of the value and effort lies under the surface Connect to back-end Efficient and flexible push notifications Track and leverage location Offline availability B2E app distribution Push upgrades z Security User authentication Malware detection Data protection Manage and enforce app versions Track problems that affect UX Ensuring continued support in a quickchanging landscape 2015 IBM Corporation
