<commit_before># The Circuit [![Build Status](https://travis-ci.org/gocircuit/circuit.svg?branch=master)](https://travis-ci.org/gocircuit/circuit) [![GoDoc](https://godoc.org/github.com/gocircuit/circuit/client?status.png)](https://godoc.org/github.com/gocircuit/circuit/client)

![A circuit-managed cloud.](https://raw.githubusercontent.com/gocircuit/circuit/master/misc/img/header.png)

Circuit is a programmable platform-as-a-service (PaaS) for management, discovery, synchronization and orchestration of services and 
hosts comprising cloud applications. Users of circuit are

* Operations engineers, who sustain cloud applications at host, process and network level
* Data scientists, who develop distributed compute pipelines by linking together and distributing third-party utilities
* Manufacturers of distributed software, who wish to codify installation and maintenance procedures in a standardized
fashion instead of communicating them through documentation (viz. MySQL)

A few technical features of circuit:

* Single- and multi-datacenter out-of-the-box
* Authentication and security of system traffic
* TCP- and UDP multicast-based (similarly to MDNS) internal node discovery
* Zero-configuration/blind-restart for ease on the host provisioning side
* Global, point-of-view consistent key/value space, where keys are hierarchical paths and 
values are control objects for data, processes, synchronizations, and so on.
* Consistency guarantees at ultra-high churn rates of physical hosts
* Command-line and programmatic access to the API
* Integration with Docker

In a typical circuit scenaio: 

* Provisioning engineers ensure newly provisioned
machines start the zero-configuration circuit server as a daemon on startup.
* Operations engineers program start-up as well as dynamic-response 
behavior via command-line tool or lanuage bindings.

Circuit programs (sequences of invocations of the circuit API) are not
declarative (as in Puppet, Chef, etc.). They are effectively imperative
programs in the [CSP](http://en.wikipedia.org/wiki/Communicating_sequential_processes) concurrency model,
which allows engineers to encode complex dynamic response behavior, spanning multiple data centers.
