  1. Java in Mobile and Cloud Viewpoint Harish Kashyap M.M. BeyondSquare 16th August 2010

  2. Java- Bit of History Java in Mobile Java in Cloud

  3. Evolution of Java • J2SE1.5 • Generics • Metadata • J2SE1.3 • HotSpot JVM • Java SE1.7 • Modules • JDK1.1 • AWT retooling • JavaBeans • JDBC, RMI 1995/96 2010 + • Java SE1.6 • Performance • JavaFX • 64 bit JVM • J2SE1.4 • Assertion • XML and JAXP • JAAS • JDK1.0 • Launched • J2SE1.2 • Reflection • Swing and MVC • J2EE and J2ME IDE NetBeans, Eclipse etc Application Framework/ Libraries Struts, Spring, Hibernate, iBatis etc Language Features JDBC, JMS, JAXP, JAXB, JAAS, EJB etc HotSpot VM , Jrockit VM Container - JVM

  4. Where are we today? Source: Oracle as on Jan 2010

  5. Where are we today? • 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) Micro Edition Standard Edition Java Fx Enterprise Edition

  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.

  7. Smart phones are making inroads Source:wikipedia

  8. Top trends in IT • Industries move between horizontal and vertical structures Source:www.visionmobile.com

  9. 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 Source:www.visionmobile.com

  10. How players stack up…

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

  14. Gartner Technology prediction Cloud computing at the Peak Predicts

  15. What is Cloud Computing? In Simple Terms, Cloud offers… Definition • Pay-per-use for computation power • Virtually infinite computation resources • Automatic on-demand scalability “A pool of abstracted, highly scalable, and managed compute infrastructure capable of hosting end-customer applications and billed by consumption” An Analogy - Electricity • “Computation Power” is now available like Electricity • You pay for what you use. • You rely on a trusted third-party providers Source: TorryHarris Business Solutions on slideshare.net

  16. Three key pillars of Cloud Infrastructure as a Service Platform as a Service Software as a Service Source: TorryHarris Business Solutions on slideshare.net

  17. Public vs Private Cloud Cloud Choices Public Cloud • On-demand resources, scalability • Shared environment Hybrid Cloud Private Cloud • Exclusive environment • Limited on-demand capabilities Public + Private cloud Externally Hosted Private Cloud On-Premise Private Cloud • Exclusive, but hosted by a third party • Limited on-demand scaling • Expensive than public cloud • Cheaper than on-premise private cloud • Possibility of co-location • Requires Initial Capital Investment • Cloud setup within Org’s data center • Control on security and audit • Based on basic virtualization • Limited on-demand scaling Source: TorryHarris Business Solutions on slideshare.net

  18. Inside a cloud… Registration, Authentication and Authorization Statistics, Deployment, Start/Stop Replicates Application on demand The face of the Cloud Facilitates Pay-per-use Enforces Security Cloud Applications The Cloud Platform Self Service Portal Identity Management Dynamic Provisioning Engine Monitoring and Management Security Subsystem Metering, Billing and Rating System Virtualized Runtime Environment (Infrastructure & Platform) Network of Physical Servers controlled by the Cloud Operating System The heart of the “Cloud” Source: TorryHarris Business Solutions on slideshare.net

  19. Amazon Web Services offering S3 – Simple Storage Service EC2 – Elastic Compute Cloud • Create a virtual server instance • Concept of AMI – Amazon Machine Image • Choose your operating system and/or s/w • SSH and SFTP to your virtual server • Web Service interface for admin tasks • File System Storage of Arbitrary Data • Each file can be 5 GB • Secure storage with ACLs • Used by SmugMug Photo Service SQS – Simple Queue Service Elastic Map Reduce • Message Queue Infrastructure • Reliable delivery` • Infrastructure for data-intensive tasks • Web indexing, data mining, log file analysis Simple DB Elastic Cloud Front • Core Database Functions • Fast Indexing, Querying and retrieval • Infrastructure for content delivery • Based on closest geographical location Source: TorryHarris Business Solutions on slideshare.net

  20. 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
