• Example: Eberhard Wolff, ex-Springhttp://www.slideshare.net/ewolff/java-application-servers-are-dead• Personally, I don’t buy into this

meme. Just as I am skeptical of “Tech Radars”.@Bodil

Resource Consumption Managers

• Deep integration between WebLogic Server and the Oracle JDK

• Prevents resource hogging, protects applications in a shared JVM

• Managed resources– Retained heap, CPU time, open file descriptors

• Triggerable actions– Notify – inform administrator that a threshold has been crossed– Slow – reduce partition’s ability to consume resources– Fail – reject requests for the resource (file descriptors only)– Stop – initiate the shut down sequence for the offending partition

• “Boundaries” and Fair Share usage patterns

Runtime Isolation Within a JVM

Multitenancy in WebLogic 12.2.1

• Agility/devops with lightweight pluggable partitions– Ultra-light container-like service packaging– Portability across environments

• High density with domain and JVM sharing– Consolidate/virtualize within domains and

JVMs

• Isolation between microcontainers– Runtime, administration, security, data

Summary

• Lambdas are a defining feature of Java 8• Coherence 12.2.1 allows you to use lambdas– Like standard Java, but both locally & in a distributed manner– Allows in-place update without locking / synchronization–With existing Coherence features (like Entry Processors, Listeners…)– To perform stream-based operations

• Coherence adds support for serialization of standard functional interfaces• Coherence handles distributed stream & lambdas in a dynamic way– Supports multiple versions of clients seamlessly running side-by-side without restart

Distributed Lambdas Rock! Imagine the possibilities!


Summary

• Stream API provides functional API for query and aggregation • Collectors eliminate the need for custom code • Coherence provides Distributed Stream API – Allows parallel processing of data streams across a cluster “in-place”– Scales multiple threads in a single process to multiple threads in multiple processes

across machines across the Coherence cluster (with high-availablity)– Provides optimizations to avoid deserialization & use indexes– Stable results even during cluster failure / recovery

• Next generation? Real-time continuous stream processing

Distributed Streaming Rocks!
