Mobile application development is a top priority for businesses 35% of developers are currently

29% of mobile developers currently

targeting tablets, with more than 90% plan to develop for tablets in the near future.

focus on Hybrid app development with another 49% expected to focus on it in the next year.

Nearly 90% of developers are currently extending enterprise apps to mobile or plan to in the near future.

More than 100M people upgraded to iOS6 in the first week (September, 2012)

In the next 12 months 77% of developers will be focused on Hybrid application development.

25+ Almost all expect to deploy more than 25 mobility applications in the next two years Source: Evans Data Mobile Developer Survey Mobile Development Report 2012 Volume Source: Business Insider (September 2012)

Mobile is a significant evolution of enterprise computing Mobile/Wireless/Cloud

Web/Desktop

Client/Server

Host/Mainframe

Mobile is different: • Transformational business models

Agile

• Faster lifecycles • More iterative • Requires open standards

But also brings business and IT challenges Enterprise Business Model Changes • New business opportunities based upon geo location • Anytime, anywhere business transactions • Importance of social business interactions

App Development Lifecycle Complexity • Built for purpose, fast, “good enough”, strong involvement of users/stakeholders • Complexity of multiple device platforms with fragmented Web, native, and hybrid model landscape • Connecting the enterprise back-end services in a secure and scalable manner • Unique mobile requirements (user interface, connected/disconnected use, version upgrades, etc.)

Mobile Security and Management • Protection of privacy and confidential information

Top Mobile Adoption Concerns: 1. Security/privacy (53%) 2. Cost of developing for multiple mobile platforms (52%) 3. Integrating cloud services to mobile devices (51%)

• Use of client-owned smartphones and tablets • Visibility, Security & Management of mobile platform requirements

Classic Web vs Web 2.0 Architecture

Characteristics

Mobile and Web Application Development Types Web Application

Mobile Web Application

Hybrid/Hybrid Mix Mobile Application

Desktop and mobile using open web (HTML, JavaScript) client programming models

Mobile only using open web (HTML5, JavaScript) client programming models

Mobile only, app runs on the device, but leverages open web (HTML5, JS) via JavaScript bridge

Off-line capabilities Limited to no devicespecific functionality

Native device capabilities (GPS, camera, contacts) Mimic native appearance Hybrid mix can have web code with native for things like navigation for maximizing user experience

Traditional Trade-offs (without MEAP/MAP)

Mobile Browser Execution

Native Mobile Application Mobile only, developed using native languages or transcode to native via MAP tools Native appearance and device capabilities, performance

AppStore download and install

Richness of Mobile Presentation / Services Portability (cross-device reuse) Maintenance Cost (TCO)

Simple topology of a hybrid mobile application with Worklight

Pattern: Application Server, Adapter Pattern Roles and tools: Mobile Client UI developer vs. server side developer, vs. adapter developer

Mobile Application Deployment Architecture


A – Mobile App
D – Mobile Device


WL – WorkLight Server


N – Network


EBE – Existing Back End


I/i – Internet/intranet


I – Internet Service

Server Side Mobile UI

Adapter

SOA Reference Architecture Services applied to Mobile Architecture

DataPower Gateway
Pattern: Reverse proxies typically front Worklight runtimes and follow the gateway pattern


Purpose: Protecting WL from the Internet, XML firewall, terminate SSL,

AAA (authentication, authorization and accounting) services, PEP (policy enforcement point)


Product Mapping: DataPower®, or IBM Security Access Manager
Roles and Tools: Administrators configure QoS

Gateway AAA (Authentication, Authorization and Accounting) Services

GW requires flexible and fast security processor

Cloud Integration via Cast Iron


Pattern – Enterprise Service Bus, elastic cloud
Purpose: “elastic client” apps integrate with location transparency - on premise or in “elastic” public or private clouds


Product mapping: The Cast Iron adapter provides OOTB integration with all cloudbased, hardware appliance or hypervisor editions of IBM WebSphere Cast Iron.


Roles and tools: Integration developers build integration flows in WebSphere Cast Iron Studio, with orchestrations mad up of a number of configurable activities

Worklight Cast Iron Adapter

Adapter Pattern
An Adapter is a transport layer used by the

Worklight Platform to connect to various backend systems. • Executed on Worklight server • Implemented in Javascript by default (can be customcoded in Java) • Simple client-side Javascript invocation model through Worklight client API

Query

Response

Update data

Caching Mechanism


Adapters are used for:

SQL

HTTP-WS

HTTP-REST

• Retrieving information CAST IRON

• Performing actions

1
Out of the box Adapter support: • SQL Adapter • HTTP Adapter (supports both REST and SOAP) • CastIron Adapter (optimized for HTTP data exchange with CastIron integration appliance) • JMS Adapter

Invoke adapter procedure

JMS

Data/Result as JSON

4

Enterprise Integration via Message Broker
Pattern – Enterprise Service Bus, Pattern Based Engineering
Purpose: integrate applications using a variety of common patterns
Product mapping: WebSphere Message Broker provides OOTB pattern integration toolkit for rapid application development.


Roles and tools: Integration developers instantiates integration patterns in WMB Studio. It generates adapters, and integration flows made up of a number of configurable nodes

Mobile Service Enablement Pattern Easily mobile-enable a message broker service!
Creates a mobile-ready interface around a Message Broker service

– Services are a first class artifact in Message Broker alongside applications and libraries – Builds an adapter to integrate Worklight and Message Broker services – Inbound data from the mobile application is sent to Worklight as JSON/HTTP

– Makes it very simple to mobile enable a Message Broker service! – The adapter passes the inbound request straight through to the service – Pattern adds an HTTP/JSON message flow (binding) to the service project

22

Resource Oriented Architecture requires security
Create –

POST /MyRESTService/ -- create a new item


Read –

GET /MyRESTService/ -- list all items

–

GET /MyRESTService/count -- get number of items

–

GET /MyRESTService/# -- get item by #


Update –

PUT /MyRESTService/# -- update an item by #


Delete –

DELETE /MyRESTService/ -- delete all items

–

DELETE /MyRESTService/# -- delete item by #

Resource Handler Pattern
Resource oriented architecture is a well known implementation pattern – Provides a common set of functions (CRUD – Create Read Update and Delete) – This pattern provides an adapter which implements CRUD operations – A Message Broker service is generated with subflows for each operation – The service integrates security authorization and authentication (LDAP) – Operations optionally integrate with the Message Broker Global Cache (WXS)

24

Extending Pub/Sub with Push Notification Services


Worklight supports asynchronous push notifications to mobile applications – Push notifications have a measurable impact on the success of mobile applications – There are many IT challenges in supporting push notifications (devices, delivery etc)

– Push notifications are applicable across many industry verticals – Healthcare, retail, travel, transportation, government, insurance and more!

– All the major mobile platforms support push notification services – Apple iOS 3, Google Android 2.2, RIM Blackberry 5 and Windows Phone 7

–Pending notifications are written to a WebSphere MQ queue by a provider application – Need to subscribe to the notifications and arrange delivery to the mobile notification server

25

Worklight Push Notification from WebSphere MQ
Creates a push notification adapter from a WebSphere MQ queue

– Generates a web service implementation which is deployed to Message Broker – Builds a Worklight integration adapter which polls for pending notifications – Pending notifications are written to a WebSphere MQ queue by a provider application – The adapter converts the notifications into JSON and arranges delivery to the device

26

Extending desktop social collaboration to mobile devices A comprehensive suite of mobile solutions for social business - with device-appropriate interfaces for Smartphones and tablets including: Apple®, Android, Research In Motion® BlackBerry®, Nokia In 2011: 44 collaboration software releases • IBM Lotus Notes Traveler -- push email, calendar, contacts • Real-time collaboration – IBM Sametime IM chat and online meetings or via IBM SmartCloud for Social Business • IBM Connections social software for access to your professional network • IBM Lotus Symphony Viewers for viewing business documents • App dev software for HTML-based mobile apps and sites – IBM Lotus Domino XPages and IBM WebSphere Portal Mobile Experience
