# About

This library provides a protocol buffer based framework for creating self

coordinating asynchronous services.

Please refer to the project website for documentation:

    http://elasticservic.es/

# Overview

The library provides tools and components to create and define services that

can communicate with each other.

A **component** is essentially a daemon that has one or more services running

on it. Components are identified by a three part **component ref** that

consists of a site id, cluster id and component id. A **service** is an

instance of a service implementation associated with a component and is

identified by a two part **service ref** consisting of a component and a

service id.

When a service wants to engage another service, it uses the **service

registry** to send a **message** to the service identified by the **service

ref**.

An example service implementation is the **gossip service**. It consists of a

service implementation that listens to **component online** and **component

status** messages that are broadcasts to a fanout topic as well as a

broadcast **work** that periodically sends out those messages for other

components to consume.

## Example: Calc

In the examples directory are the calc-service and calc-webapp maven modules.

The calc-service module includes a calculation service that listens to add

messages and responds with result messages. It is an example of a standalone

JSVC based daemon.

The calc-webapp module includes a spring-based HTTP API that engages the calc

service. It includes an example edge service that demonstrates how

synchronous projects, like HTTP edges, can engage asynchronous services.
