More on the JavaOne 2013 Strategy Keynote - IBM's Java Focus

John Duimovich, Java CTO and IBM Distinguished Engineer, took the stage at Sunday’s JavaOne 2013 keynote and stated that IBM had a new approach to this year’s JavaOne. They arrived at JavaOne with 20 developers of all ranks, giving 28 sessions -- and only one marketing person. This was consistent with a mantra he repeated throughout his keynote: “It’s a great time to be a developer.” Duimovich also commented several times that developers ultimately have a lot of power, a recognition that leads IBM to shape many policies around the needs and desires of developers.

“With so many frameworks, languages and tools available, developers have all they need to create great applications,” he observed. “With the cloud and PaaS it is easy to go to market and, in fact, possible to take a good idea, test it, and deploy it within a day.” This, he insisted, has changed the landscape for developers. Since Java is the leading platform being used to deploy to the cloud, along with Javascript and HTML5, IBM will continue to follow and invest in developers.

Systems of Interaction and Engagement
Duimovich identified an interesting turn of events. “There is a new class of application development out there now called systems of interaction, which are typically delivered via the cloud." “Systems of interaction” is a term that encompasses what has traditionally been called systems of record, which are what many Java developers work with in Java EE using containers and databases in such domains as business process-oriented bank accounts and HR systems.

He observed that there are new and growing open cloud ecosystems centered around such platforms and projects as CloudFoundry and OpenStack, offering the next “big thing” for developers -- the ability to access a whole open stack and write applications. “What’s different about IBM is that we are investing in open things a bit earlier in their life cycle,” said Duimovich. “We don’t wait until they are done and competing with us. We try to influence them early.”

New applications are being developed that offer systems of interaction which he characterized as user-centric applications specifically targeted to support user work flow.  These are mobile apps similar to what is in a phone or a car that bridge both systems of record and social networks. “So the application might take Twitter or Facebook into account, while bridging big data and bring together capabilities that drive user-focused applications,” explained Duimovich. “You are on the way to the airport and the app tells you the plane is late; you take off and the app tells you about the weather in the city of arrival. After that, you might be interested in where to buy new clothes because your luggage is still at the airline.”

Such applications have contextual “awareness” driving them. All of this is driven by the cloud as systems of record get pushed out to the cloud as services. “IBM has created an experimental platform that developers can try out called IBM BlueMix which is based on OpenSource and CloudFoundry,” said Duimovich. “It has runtimes and frameworks, like Java, and new ones like Node, and other scripting languages like Ruby.”

IBM BlueMix offers standard services such as database, caching, and messaging, but also includes new ones like social information, and location and geo-spatial database information. “This is all brought together so the enterprise can engage with their customers in a much richer way -- the way they do that is via the cloud.”

Java Innovation at IBM
He discussed the IBM WebSphere Liberty Buildpack, which is freely available for developers. It can be downloaded and pushed to any Cloud Foundry-based system. “This is our first step in making Java to PaaS deployment as easy as possible for developers.” Liberty is a Java profile that supports Java EE and is a container offering lots of features for clouds.

IBM has also been working on a multi-tenancy JVM, which means the VM can run and stack more VMs inside of it to save space and enable faster startup performance. This allows developers to manage life cycles independently. It’s intended for those who want to get more dense and efficient deployment on the cloud. “Just as peanut butter and chocolate go together – Liberty and multi-tenancy VMs are delicious,” said Duimovich.

He explained that running the Liberty profile and on the multi-tenancy JDK results in 2-3 times faster startup and twice as much density, so developers can stack twice as many instances on a machine than before without loss of performance.

Duimovich closed with some remarks about hardware innovation at IBM, and where the Java language may be headed in the future.

JavaOne 2012 Conference Preview

A new article, by noted freelancer Steve Meloan, now up on otn/java, titled “JavaOne 2012 Conference Preview,” looks ahead to the fast approaching JavaOne 2012 Conference, scheduled for September 30-October 4 in San Francisco. The Conference will celebrate and highlight one of the world’s leading technologies. As Meloan states, “With 9 million Java developers worldwide, 5 billion Java cards in use, 3 billion mobile phones running Java, 1 billion Java downloads each year, and 100 percent of Blu-ray disk players and 97 percent of enterprise desktops running Java, Java is a technology that literally permeates our world.”

The 2012 JavaOne is organized under seven technical tracks:

* Core Java Platform
* Development Tools and Techniques
* Emerging Languages on the JVM
* Enterprise Service Architectures and the Cloud
* Java EE Web Profile and Platform Technologies
* Java ME, Java Card, Embedded, and Devices
* JavaFX and Rich User Experiences

Conference keynotes will lay out the Java roadmap. For the Sunday keynote, such Oracle luminaries as Cameron Purdy, Vice President of Development; Nandini Ramani, Vice President of Engineering, Java Client and Mobile Platforms; Richard Bair, Chief Architect, Client Java Platform; and Mark Reinhold, Chief Architect, Java Platform will be presenting.

For the Thursday IBM keynote, Jason McGee, Distinguished Engineer and Chief Architect for IBM PureApplication System, and John Duimovich, Java CTO and IBM Distinguished Engineer, will explore Java and IBM's cloud-based initiatives.
All in all, the JavaOne 2012 Conference should be as exciting as ever.
