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

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

PolyglotCloud



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
