Why do I need it?Mmm Tasty!
SaltStack is systems management software built for cloud, Web scale, complex data center infrastructure and enterprise IT.
SaltStack software provides predictive infrastructure orchestration, combined with native configuration management, to address a massive market opportunity.

Why do I need it?
•Extremely flexible•Extremely extensible•Highly modular•Easy to customize•Scalable•Secure•Remote Execution Framework
SaltStack… because robots should have all the crap jobs by now!
Remote Execution 101Make it go!
Basic Remote Execution:
$ ssh charles@myhost “ls /home/charles” some_file.txt
Multiple hosts:
$ for h in myhost1 myhost2 myhost3;> do ssh charles@myhost “ls /home/charles”;> done
Remote Execution 101Make it do!
What about hundreds of hosts?
And I need to do this many times?
With different login credentials on some?
What if I need to do something with the output?
Remote Execution 101and going…
How about a script?
#!/bin/bash# Make sure your SSH config (~/.ssh/config) is setup!
command=$1host_list=$2for h in host_list; do ssh “$h” “$command”done
# FIXME: Add output handling# FIXME: Add error handling# FIXME: Add logging# TODO: FIND A BETTER WAY TO DO THIS!!!
Remote Execution 101and doing…
We need a script that can handle:
Executing arbitrary commands… on one or more remote hosts… with a sane way to get the output (STDOUT? Write a file? Text Output? JSON? YAML???)… and graceful error handling… and logging… and authentication… everything else I haven’t thought of yet!
Remote Execution 101The Realization Sets In…
We only want to run a command if the host is in a particular state…
The command is different for some hosts because they have a different OS
We need to configure host X before we configure host Y
We want to generate a file from a template, using data from an external database
We need to keep that external data secret
Say What?
You want me to maintain a 5,000 line BASH script?

Extreme flexibility:• Master and minion architecture, or masterless;• Agent (minion) or agentless (Salt SSH);• Permanent, encrypted and authenticated connection (ZeroMQ / AES);• Open API for third-party cloud and software integration;• Asynchronous data collection and command execution;• Push or pull;• Lightweight and efficient;

Master (controls minions):• Pub / sub and reply channel;• Two open ports on master;• Multi-master for SaltStack high availability.
Minions (do all the work, self aware):• Listen and receive commands from a remote Salt master;• No open ports;• Not chatty;• Command feedback;• Peer system - live data sharing between minions;• Salt mine - only the most recent minion data, cached data is visible to other minions;• Returners - historical minion data;• Syndic (a special minion that passes commands from a higher master);
