APIs are essential to composable business
APIs
Well designed APIs
• Do something useful
• Hide the complexity
• Have a simple interface
• Are easy to share and reuse
• Are well documented
• Can be used both inside and
outside the company
• Can be combined with other APIs

JavaOne 2015 Cask Strength Java: Aged 20 Years 12
20 years, eh ?

IBM and Java: Happy 20th Birthday!
 IBM is a long-term licensees of Java, shipping compliant Java runtimes for 20 years
– Compliance, developer ecosystem, specifications, competitive runtimes and broad industry support
 First IBM JDKs supported 1.1.x
– Basic “Classic” port
 Second Generation added (up to 1.42)
– High performance Sovereign JIT, scalable garbage collectors
– Security including HW acceleration
– ORB (IDL, RMI)
– XML (Xerces / Xalan)
– Jikes RVM – a JVM written fully in Java!
 Third Generation (Java 5 and up)
– New Runtime– The J9 Virtual Machine and Testarossa JIT, modular, high performance
– Configurable embedded runtime to high “watch to a mainframe”
– Generational Type Accurate GC, Region Based GC (Balanced)
– Dynamic DLLs (Shared Classes)
– GPU Acceleration

Java for Big Data: Apache Spark
• Java's deep performance optimization enabler for new platforms
• Scala, Apache Spark, Apache Hadoop Big Data stack
• Optimization has delivered double digit percentage improvements
• JIT feedback to language/platform designers,
• New serialization optimizations
• Next Generation POWER and System Z offload exploitation
• Security – microcoded crypto algorithms
• RDMA – faster networking IO
• CAPI/Flash – faster persistence for RDDs
• FPGA – custom compression codecs
• GPU – highly concurrent algorithm offloading

JavaScript (yes, I know, it’s not Java)
 Node.js is a leading emerging standard for creating APIs and microservices
– Key for enabling mobile, IoT and new web applications
 Applications are being build with scalable APIs and microservices for Hybrid Cloud.
– Our customers are driving to digital transformation and are building out from Java applications
 Rapid innovation being driven by the Node.js and JavaScript communities
– Java ecosystem can learn from this
 Open Ecosystems enable interaction, learning, innovation!
– How can the Java and Node.js communities accelerate developer innovation?
– How can the Java and Node.js ecosystems drive interop, best practices?
 Solve new problems facing developers – multi-language application debug, diagnostics, trace

What could John do in an hour and a IBM Vice
President could demo?
(yeah, it’s that easy)

Fun with words and analytics

Personality Insights Java Starter Application
The Watson Personality Insights service uses linguistic analytics to extract a spectrum of
cognitive and social characteristics from the text data that a person generates through text
messages, tweets, posts, and more.
