Sounds impressive, doesn't it? And now, add to all of this the ecological requirements for the impact on the environment, and it turns out that what seemed to be the most important thing - servers with computing resources and network equipment - is almost the simplest component of the data center.
The complexity and value of the energy and cooling systems are truly enormous and require highly skilled engineers who deal with them. After all, if one or two servers fail or the network gateway goes down, the damage will not be as great as if the power or cooling system of the entire data center fails.
But that's not all. There are other departments in the data center without which its life is impossible. These are security personnel responsible for both protecting against information incidents and for the "physical" security of the data center. And if we are all more or less familiar with information security, when it comes to "physical" security, we think of towers with automatic weapons and patrols with dogs :) But I think in reality it is more likely to be a number of cameras with an intelligent image analysis system and a security squad capable of catching fast perimeter violators.
And one more thing we need to mention is management. All the parts and teams o the data centers need to be managed somehow. Moreover, managed in such a way that the number of incidents leading to hardware and connectivity failures tends toward zero. And as we know from Murphy's Laws
, anything can break down at the most inappropriate moment.
Here are several rules that data center managers follow:
- Every action is regulated by protocols.
- Every incident must be analyzed, and the corresponding protocol should be revised to prevent similar incidents from occurring in the future.
- Regular training, certification, and testing of employees.
- Regular "training" incidents and practical exercises.
- Regular external audits.
- Maximum independence from the human factor.
We can talk about data centers for a very long time, because the topic is very complex, and at the same time extremely interesting. However, the article format is not infinite. I have tried to explain in simple language how data centers work and show it’s complexity (and attractiveness).

Well, that's all I have for now. Thank you for your attention!
