What does the operation and maintenance engineer do every day?

When it comes to operation and maintenance engineers, most people think they repair computers. In fact, the operation and maintenance engineer's job is not so simple. Operation and maintenance literally understand that operation is operation and maintenance is maintenance. Then the function of the operation and maintenance engineer is to ensure the normal operation of the business and maintain it in time when problems occur.

Use professional terms to explain that the operation and maintenance engineer is responsible for maintaining and ensuring the high availability of the entire service system, while continuously optimizing the system architecture to improve deployment efficiency, optimize resource utilization and improve the overall ROI. Operation and maintenance engineer is a collective name, which has many classifications. Including: desktop operation and maintenance engineer, network operation and maintenance engineer, system operation and maintenance engineer, basic operation and maintenance engineer, etc., their division is mainly based on the difference of specific work content.

Operation and maintenance engineers are most busy when they complete a project product, and sometimes need to work overtime for several weeks. They play different roles at different stages of product project completion. So in fact they have a lot of work:

Before product launch: Responsible for participating in and reviewing the rationality and operability of the architecture design to ensure efficient and stable operation after product launch.

Product release stage: Responsible for using automated technology or platform to ensure that the product can be released and launched efficiently, and then iterate quickly and steadily.

Product operation and maintenance phase: responsible for ensuring the stable operation of the product 7 * 24H, during which various problems can be quickly located and resolved; in the daily work, the system architecture and the rationality of deployment are continuously optimized to improve the stability of system services .

Operation and maintenance engineer is a profession that requires twenty-four hours online, because you don't know when the system needs you to maintain. So even if you take a vacation at home, you need to take action when you need an operation and maintenance engineer.

Operation and maintenance engineers will have many business requirements. If the operation and maintenance engineers can meet the business requirements or actively explore the pain points and improvement methods of the business, they can realize more value for the business. The business interruption caused by the failure will definitely cause losses, so it can be repaired before the illness occurs. This is the core value of the operation and maintenance engineer. When meeting business needs, priority is given to the very important requirements of rapid business development, such as stability, deployment and change efficiency, and capacity management.

Then there is no daily project, what are the operation and maintenance engineers doing, are they playing mobile phones idle? Of course not, if you do, you will be fired. What is the daily work of the operation and maintenance engineer?

Regularly inspect the network server, database server, and Internet server in the computer room daily to check whether it is working properly and whether the company's website can be accessed normally. Inspect the terminal computers, printers, copiers and other equipment of the computer system daily. Whether there are incorrect operation and use, and whether there is equipment with faulty work; automatic real-time backup of financial software every night after everyone is off work, physical data backup once a week, and logical backup verification work in the backup server ; Make physical data backups to the file server at least once a week; and deal with various network-related emergencies. Of course, the operation and maintenance engineers of each company are engaged in similar work, and some companies may arrange other tasks for the operation and maintenance engineer.

So the students who are learning to be an operation and maintenance engineer and the students who want to become an operation and maintenance engineer, do they know a little bit more about the content of the job they want to do? In the future, when someone asks what the operation and maintenance engineer is doing, don't let others think that it is a computer repair. And after looking at the work content, do you have the confidence to become a leader in operation and maintenance engineers?
