Where are we today?

9 million Java developers

840 million Java desktop installations

100+ different hardware platforms supported million Java desktop installations

5.5 billion Java cards

2.6 billion Java-enabled cell phones250 partner cell phone carriers

100,000+ Java ME applications

40 million TVs and Blu-ray players

Where are we today?

Enterprise Edition

Standard Edition

Micro Edition

• Java SE for the desktop• Java EE for server and enterprise solutions• Java ME for embedded and mobile devices• JavaFX to build rich Internet applications, with media

capabilities for desktop computers, mobile devices, and television (set-top boxes, Blu-ray players, and so on)

Java Fx

6

The Java ME platform covers everything from small limited devices with intermittent network connection to capable on-line mobile devices

• 16-bit or 32-bit CPU with a clock speed of 16 MHz or higher

• At least 160 KB ROM allocated for the CLDC libraries and virtual machine

• At least 192 KB total RAM available to the Java platform

• Low power consumption, often operating on battery power

• Connectivity to some kind of network, often with a wireless, intermittent connection and limited bandwidth

• Devices that support CDC typically include a 32-bit microprocessor/controller and make about 2 MB of RAM and 2.5 MB of ROM available to the Java application environment.

Top trends in IT

• Industries move between horizontal and vertical structures

Network services are moving from vertical to horizontal while handset OEM is moving the other way around

• Players are at different stages towards verticalisation or horizontalisation

Too many platforms… space to watch out for

2nd party platforms

• designed for building phones• aimed at OEM• using legacy code• intended for core apps

3rd party platforms

• designed for building apps• aimed at any application developer• using modern platforms• intended for downloadable apps

12

Few key platforms

Brew:

•Used for deploying applications on CDMA devices •Little penetration in Europe.•Qualcomm•More advanced 3d capabilities than J2ME•Does not run on all devices. Need digital signature to be issued•Written in C, has Java API available

Symbian

•Most widely used, written specifically for mobile devices•Supported by Nokia, Sony Ericson, Samsung, NTT DOCOMO•Java API available•Relies on QT technology

Android

•Linux based•Can develop apps in Java but runs on C/C++ runtime. •Supported by HTC, Google, ChinaMobile and quite a few other players•Is not completely J2ME compliant

Apple iOS

Others•Samsung Bada•Nokia MEEGO•Blackberry OS

13

Other key trends

• Mobile advertising will surpass the traditional web based advertising

• Tablet devices will become the pretty much part of all our lives

• Many makers of smart phones. Diversity will continue to exist

• Everything and everybody join the network

• Service providers (with SIM) will find hard to survive. Quite a few phones will run without a SIM card.

• Content will be the king and mostly tied up with network. Network as a service

• Cool mobile apps for consumer and business

• Consolidation will happen based on OEM, Network provider and carrier strategy

• Consolidation of java platforms to Java SE and eventually Java ME may no longer need to be micro!

Gartner Technology prediction

Cloud computing at the Peak

Predicts

15

What is Cloud Computing?

“A pool of abstracted, highly scalable, and managed compute infrastructure

capable of hosting end-customer applications and billed by consumption”

DefinitionIn Simple Terms, Cloud offers…

Pay-per-use for computation power

Virtually infinite computation resources

Automatic on-demand scalability

An Analogy - Electricity

“Computation Power” is now available like Electricity

You pay for what you use.

You rely on a trusted third-party providers

Google App Engine

• The Google App Engine Java environment provides – Java 6 JVM, – Java Servlets interface, – Supports standard interfaces for data store and services

like Java Data Objects, Java Persistence API, JavaMail, Jcache, etc.

– The App Engine uses the Java Servlet standard for web applications, whereby the user or developer provides the application's servlet classes, JSP pages and other files along with the deployment descriptor (web.xml) in a standard WAR directory structure.

• The applications are run in a secure 'sandbox' environment to isolate the application for service and security. This means that an application cannot spawn threads, or write data to local system files, thus ensuring that the application does not interfere with performance for other applications on the cloud infrastructure.

21

Java is a natural fit to cloud – as per Oracle Java developers!

• Elasticity: you can fire up new instances on demand

• Management and Monitoring: especially applications in the "cloud" have higher requirements regarding management and monitoring. You should be able to pro-actively monitor the current state of your application

• Vendor neutrality

• Standardized packaging and installation: you will have to package your application to install it to a "cloud". Standards are always good, otherwise you will end up in many negotiations and meetings.

• Failover capabilities

• Easy administration: you will need remote administration tools.

• Low resource consumption: computing time and resources cost a lot. It is important to build as lean applications as possible to save money.

22

Few PAAS offering

• BungeeConnect, proprietery platform• Aptana, more of an IDE than an run time engine. Runs on EC2• Force.com, collaboration of VMWare and Salesforce.com, runs on

salesforce.com IAAS• JBoss Cloud, runs on EC2• Stax, runs on EC2• Google App Engine• 10gen, supports multiple cloud
