We believe screen casts give the best introduction to new concepts, so we’ve recorded several to complement the documentation.
Introductions and Guides

- Software Deployer used by developers
- Managing clusters of Exim Servers
- Bootstrapping Puppet on EC2
This video introduces the basic concepts behind MCollective. It predates the SimpleRPC framework but is still valid today.
Message Flow, Terminology and Components
This video introduces the messaging concepts you need to know about when using MCollective. It shows how the components talk with each other and what software needs to be installed where on your network. Viewing this prior to starting your deployment is recommended.
We also have a page detailing the Terminology
How to write an Agent, DDL and Client
Writing agents are easy, we have good documentation that can be used as a reference, this video should show you how to tie it all together though. See the SimpleRPC Introduction for reference wiki pages after viewing this video.
The SimpleRPC DDL
The Data Definition Language helps your clients produce more user friendly output, it ensures input gets validated while showing online help, and it enables dynamic generation of user interfaces. After you have watched the video, you can refer to the DDL wiki page for more information.
SimpleRPC DDL enhanced IRB
Based on the SimpleRPC DDL, this custom IRB shell supports command completion.
Software Deployer using MCollective
If you ever do commissioned work based on MCollective, this deployer written using SimpleRPC may be of use. It can be used by developers to deploy applications live into production using a defined API and process.
Managing Exim Clusters
A command line and dialog-based UI written to manage clusters of Exim Servers.
The code for this is open source. Unfortunately it predates SimpleRPC; we hope to port it soon.
Bootstrapping Puppet on EC2 with MCollective
Modern cloud environments present a lot of challenges to automation. However, with MCollective and some existing open source agents and plugins you can completely automate the entire process of provisioning EC2 nodes using Puppet.
