What about APIs, Microservices, Mobile, Analytics ?



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

• Delivers 10x to 80x performance improvement in key components

Polyglot Cloud



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.
