Remote Objects

GPars already has single JVM

concurrency and parallelism.

You can use it from Javaas well as Groovy.

GPars now has remote objects.

Realized by using Netty.

ActorsIndependent processes communicating via asynchronous exchange of messages.

DataflowOperators connected by channels with activity triggered by arrival of data on the channels.

Data ParallelismTransform a sequence to another sequence where all individual actions happen at the same time.

CSPOperators connected by channels with activity triggered by arrival of data on the channels.

Active ObjectsAn object that is actually an actor but looks like a full service object.

AgentsA wrapper for some shared mutable state.

Software Transactional MemoryWrappers for mutable values that uses transactions rather than locks.

Fork/JoinAn toolkit for tree structured concurrency and parallelism.

CSPSequential processes communicating by sending messages on channels.

Hadoop

Service Oriented Architecture

Services

Micro-Services

Pico-Services

No HTTP, Web, port 80, HTML, CSS..
