<h1>About Devophp</h1>
<p>Devophp is a set of decoupled devops components, implemented in PHP.
It provides a core platform for communication that can be used for a wide range of practical solutions. For example:</p>
<ul>
<li>System monitorring</li>
<li>Distributed firewall management</li>
<li>Metrics collection</li>
<li>Configuration management</li>
<li>Application deployment</li>
<li>Distributed commands</li>
<li>… etc, it’s easy to add new plugins</li>
</ul>
<p>Think of it as nice blend between nagios, puppet, collectd, statsd, capistrano, mcollective, shipyard, security groups, cloudformation and more.</p>
<p>The system is message-based, meaning that all communication flows through a message broker. There are no complicated firewall rules to set up on your nodes, all traffic is outbound to the message broker.</p>
<p>The code-base is designed with simplicity and extensibility in mind. It’s easy to build new functionality on the existing components.</p>
<p>Projects can be used together for a full solution, or individually, as building blocks.</p>
<h2>The big picture</h2>
<p><center>
<img src="images/devophp_overview.svg" style="width: 75%;" />
</center></p>
<p>The 3 primary components of a Devophp setup are:</p>
<ol>
<li>The agent (running on all of your nodes)</li>
<li>The message queue</li>
<li>The monitor</li>
</ol>
<p>None of the components communicate directly with eachother. All communication runs through the message queue.</p>
<h3>The agent</h3>
<p>The agent is installed on all of the nodes you wish to manage through Devophp.</p>
<p>It listens for commands on the message queue to be executed on the node.</p>
<p><a href="/agent">Read more</a></p>
<h3>The message queue</h3>
<p>The message queue is the communication channel between all of the components.</p>
<p>Currently the components support the STOMP protocol, which is implemented by Apache ActiveMQ.</p>
<p>Other message queues such as SQS or RabbitMQ can be supported by implementing a simple interface.</p>
<h3>The monitor</h3>
<p>The Monitor component is keeping an eye on all of the nodes running the agent.
It schedules jobs (such as system checks), and processes reports coming back from the agents.</p>
