I would like to ask: operation and maintenance engineer, what is the work intensity?

Is the work intensity of operation and maintenance engineers lower than that of development engineers?

Whether the work intensity is low or not depends on each company. A company's operation and maintenance intensity is very strong. Basically, I have to work overtime when I go back at night, mainly because there are few people. The operation and maintenance intensity of Company B is directly proportional to the per capita load. Although I have worked for B (a supplier of B has been to B for a while before), I am not sure about B now;

2. Will the technical content of operation and maintenance engineers be lower? So the pressure is less?

–The nature of operation and maintenance is mainly to maintain smooth and efficient operation, including installation and debugging of software and hardware, configuration of server software according to different development projects, monitoring and other things; Compared with development, it is more inclined to operating system or database (these are two directions, which are generally taken separately); However, development tends to develop software and some middleware, and databases and systems are generally checked by operation and maintenance personnel;

A.DBA prefers software, OS administrators and network administrators (such as Cisco) prefer the combination of software and hardware, and some people simply play with hardware (installing server hardware, cabinets and the like);

B as for the technical content, I personally think that the more things are integrated, the less people worry about it, and the technology of different positions is not comparable. The key depends on your personality; C. Compared with development, the experience learning cost of operation and maintenance is relatively high, which means that you can't learn real skills without a certain practical environment, but you can find the general idea by sitting at home; The knowledge update speed of operation and maintenance is relatively slow. The knowledge update of DBA 10 years ago may be only 50%, and he himself will be very valuable, while some contents of java may not have been invented two years ago. Unless you are in a management position in development, the cost of pure technology development, learning and updating will be high; Conversely, technology development is suitable for those who prefer novelty and innovation, and operation and maintenance are suitable for those who follow the rules and are more practical;

3. In B, the salary of operation and maintenance engineer is only about 2/3 of that of development. Is it the same in your company?

Personally, I think the salary given by the company to different positions is definitely in direct proportion to his estimated importance and work intensity of this position, but it is not known whether it is in direct proportion to the future development. It is comparable within B. As for A, I don't know much about it. After all, A's operation and maintenance is already the world's leading, with a small number of people.

4. What is the development prospect of operation and maintenance engineers? Will there be less room for future development?

The so-called development space should be combined with your personal character. Senior DBA is still scarce on the earth. I know that the DBA of ebay's China operation center drives a BMW to work, and the operation and maintenance is not a youth meal. The older you get, the more popular you become. It can be said to be a smooth and upward straight line. If you are just an executor and coder, I am afraid it is a curve that starts to soar and then plummets. After all, the metabolic cost of developing knowledge is too high, and it will drop after the age of 30.

What are the main jobs of operation and maintenance engineers needed by software companies?

Is to do software implementation, that is to say, implementation engineers are running around now, maintaining software! Teach others how to use software and promote it.
