Likewise, in a factory that is fully automated thing will start and stop automatically. Things will happen automatically all the time. Not magically because there is obviously code behind it.
If a person would have to press a button each time something has to happen it would not be an automated factory.
But it had to be setup to do so in the first place.
Yes, true. That the job of automation engineers in that case.
An automated assembly line for instance would have robots working on it. Someone has to program them initially.
If it was humans working on the assembly line it would not be an automated assembly line.
Right, exactly like Salt or Ansible or Puppet. Set it and away it goes. You only need to get involved if you want to modify the automation.

Okay, everyone hold up. The issue has to be that @Pete-S isn't understanding what these tools are and is thinking that they are remote access tools like MeshCental or ScreenConnect and isn't understanding that they are state engines which, by definition, are automation as there can be no human intervention in the state machine.
So the discussion going on is going to go nowhere and just be an argument unless we address explaining that the underlying problem is that he's not trying to redefine automation, but doesn't know what Ansible and Salt are for.
We are all trying to describe automation, but everyone agrees on what automation is. It's that Salt is automation is what is being missed.
-
So let's start with this... once SaltStack is set up, what does @Pete-S think that the role of a human would be?

Right, but again, just like Ansible or Salt. You seem to be arguing that they are automation with each example.
And that factory is run by.... just a script. That's what does that automation there.
No, it's not the script per se that makes it automated. It's the behavior of the system.
When you have set up ansible for instance you still don't have any automation anywhere. And you have nowhere to define automatic behaviors or responses. -

See... but that is the ENTIRE purpose of Ansible. All of it. Ansible is the "behaviours and responses" system. Without that, it doesn't exist.

Because that is what the Automation Engineer is doing. Settingup Ansible.

Do you agree that a script will produce the same result on different pieces of hardware that are running the same software components, repeatedly?
If so, then you must agree that a script automates a process of some type. Install these pieces of software, configure these printers, do XY and Z.
A script automates <something>.
And by automate, it's installing or doing whatever you have the script configured to do.

It seems like he's thinking about automation as, say, load balancing. Two servers responding to whatever variables on their own.

But a script doesn't just "come into existence" a script has to be created by an automation engineer. I was actually just wearing my AE hat about an hour ago.
Ansible/Salt etc are an AE's workshop, it's where they create the scripts that they want to be run in the environment.
You can have a building with machines in it, but unless the AE sets those machines up to be automated, they'd just be pieces of machinery sitting there waiting to do something.

Which Ansible and Salt will do
That's one of their use cases. -

That's one of their use cases.But they don't do nothing on their own. If you could define in Ansible that you wanted it to automatically install a new webserver VM when the load on the current VMs are over 60% for 10 minutes and change a load balancer to start using the new host. And it would keep doing this, adding VMs, as long as it is needed and then when load is under say 10% for an hour it would go destroy the VMs one by one. That would be automation.

Of course not. FFS
That is the AEs job.

No, you misread that.

That is one level of automation. The script/process that monitors and issues the command to create/destroy.

But it is a totally different level of automaiton that configures and sets up the instance itself. That is the process/script being called by the process/script that monitors.

And that's what it does.

They do everything on their own.

Right either the automation is inside these tools, or they automate another tool. But the end result is end to end automation.

If the tools were really automation tools they would have all this and much more.
Ansible is like an actuator. Something that makes another thing move, turn, open, close etc.
With Ansible as an example, you can define the state of a system and when you run the script it will put the system in that state by installing, removing, changing files, running commands etc.That's great but it lacks the automation parts that makes things automatic. It lacks what is called a control system, which is where you define behaviors. X will happen when situation Y happens.
You could cobble that part together with scripts just like you could do the actuator part without ansible and just scripts. And you could cobble together fetching inputs from the systems which is what you will base decisions on. For it to be called an automation tool you would really need all these components inside and they are not there.

@Pete-S
The product automation but they need heck a lot of manual labor.
