What technology stack should a sought-after system administrator have?

Question

System administration

Good afternoon! I have been working in a large company for 2 years as a system administrator. I watch a lot of courses, read books, but I understand that my knowledge is mediocre.
I understand perfectly well that the profession is in a complete ass and it looks like it will get worse in the future. Often there are questions about what other area it should go to, but I still can’t find answers, since many answers about popular web and mobile development are negative.
Therefore, I want to ask, in your opinion, in order to be in demand and competitive system administrator with a decent salary, what technologies should he know and what should he be able to do?
What to study in general, what video courses, books, in order to be a successful and highly paid specialist, with the opportunity to take part-time jobs? Thanks to all

Answer 1

I propose to consider the option of moving to a banking systems engineer. You must be able to deploy oracle weblogic, ibm websphere application servers. At least basic knowledge of java. But be sure to be able to write scripts in bash, sql and python. And be sure to learn English!
I myself worked as a system administrator. And I also realized at one time that this is a road to nowhere with a low salary. Everyone tried to go into development. And then I accidentally received an offer not as a developer, but in support on the 2nd line. After 3 years, he moved from Saratov to Moscow. I corrected my resume, that I am now a Muscovite, and offers poured in every day. Many vacancies were under 200k required the presence of spoken English. There were also proposals from Poland and the UK.

Answer 2

The system administrator must have the skills and abilities that the employer requires.
What kind of skills and abilities are required - ask the employer.

with a decent salary

The salary does not depend on the knowledge and skills of the system administrator, but on the ability to find a well-paid job.

Answer 3

TS is asking a stupid question. For 90% of employers in our vast country, a system administrator (he is also a programmer) is the one who fills the cartridges, removes the paper stuck with paper clips from the prints, and interrupts the Windows, with the office \ 1s \ other software. And where the "enikey" button is located, it shows users. For the right salary. Therefore, the level of knowledge - exclusively rests on the requirements of a particular employer. It is enough for someone to refill cartridges and that's it, you have already been accepted by the system administrator. And for someone to administer a whole data center with a bunch of web / database services and other machine / software zoo.

programmers:

, trolleybuses, trams, metro and

Answer 5

There is a basic set of knowledge, like: mail, Internet, domain, accounting terminal, printing, access, something else.
All this must be able to configure either from scratch or maintain. I want to say that if you understand, for example, how mail and spam filter work, then the name of the mail software will not matter in principle. You will work with him, etc.
To fill your head with different video courses, I'm not sure that this makes sense without practice.

Answer 6

First you need to learn what a stack is. If you have knowledge in the form of a stack, then you are a very mediocre system administrator. This is where the stupid question comes from.
On business. We study the requirements and salary in your region. It may turn out that your knowledge is in your head, but you can’t find the sn anymore. Then we take other regions. Secondly, with a swoop like this devops, web ... You should like the work. Otherwise, you will be mediocre there. Thirdly, as mentioned above, employers have different requirements.

Answer 7

Sysadmins are different. From networkers, security specialists, infrastructure specialists, SP telephonists to devops engineers, build engineers and other development participants. Everywhere knowledge is required.

Answer 8

Therefore, I want to ask, in your opinion, in order to be in demand and competitive system administrator with a decent salary, what technologies should he know and what should he be able to do?

Everything.
Well, or at least understand your strengths and look at what knowledge is not enough for a “dream job”.
As Artem wrote above , you need to find out what the client wants and are drawn in that direction.
Most often, if you do not apply for the position of the head of the department, then even with not a big lack of knowledge but a good base, you will be hired and taught the missing skills.

Answer 9

Well, actually, first you need to decide for yourself what you like best? Support and everything around him? Printers, replacing cartridges, registering for a domain? Maybe a server? Windows or Linux? Database? Network devices?
If you feel sick from the console, then what difference does it make what your skills will be ... While you are dealing with your addictions, learn English. At least to the level of understanding the meaning of what is written in a random article on the flow.
Again, change a couple of offices, work in a large federal + medium in the region. Everywhere there are business processes, somewhere the system administrator is a pillar on which everything rests, and somewhere just another cog. Good salaries can be found here and there.

Answer 10

He must have one skill, very quickly master what is in trend today. English is required. Basic programming skills are required.

Answer 11

The ability to sell yourself is a must have. The rest is at the discretion of the employer.
