DevOps how does the enterprise look from the inside?

Question

Devops

Good day! Trying to understand devops but can't even imagine what the IT structure of an average software development enterprise is. I myself am a system administrator, and now I want to master DevOps, but what is the environment there? In all the manuals that I read, there is Kubernetes, here there is a docker and they interact with each other, and here we have Zabbix, he is listening.
But how much to hang in grams?
As usual, I look at the enterprise, here there is a stack of hypervisors, on one there is a cluster management role, on this server the controller is spinning, on the third 1C, and there is Mikrotik ... etc.
DevOps they have a couple of servers, docker, kubernetes, ansible and all? DevOps is a bigger system administrator, do they even have controllers there, backup systems?
Please don't throw tomatoes at me, I just can't figure out what DevOps actually does besides what they write on the internet. I would be very happy if someone gives an example of the structure of the enterprise in which he worked.

Answer 1

DevOps is a development culture and a set of practices that must be implemented. System engineers, developers and testers are primarily engaged in this jointly. But in general, a lot more people are involved in this.

Answer 2

Docker is just infrastructure.
Devops position is the ability to work with CI / CD tools and infrastructure automation.
There is just such a thing - the position of junior Devops is bad manners, because a devops engineer is needed in medium and large projects, and developers can cope with this in small ones.
Therefore, the position of a Devops engineer is usually where the project structure is complex, hence the opinion that everything is complicated, cool, and so on for Devops.

Answer 3

Nutria is against it, but DevOps looks exactly as it is implemented there, somewhere everything is beautiful, somewhere through pain and suffering.
