Why does the server need maintenance?

Why do you want to do server maintenance?

As an important part of the Internet, the server plays a very important role. Banks, supermarkets, hospitals and other industries are inseparable from the support of server 7*24*365. When the equipment works normally, people won't realize its importance, but the server crashes, users can't deposit and withdraw money in the bank, the products in the supermarket have no price, and the drug prices and patient information in the hospital can't be extracted in time. These problems come one after another because of server failures, and only complaints and maintenance are in front of managers and administrators. As an administrator, he is responsible for maintaining server stability and reducing failures. No one wants to see the server fail. Tell everyone why you need to upgrade and maintain. If you don't have professional skills, hiring technicians to maintain a server is too expensive. Then you can consider server maintenance services, which greatly saves costs! If the salary of a professional server maintainer with good technical level is at least 3000 yuan, then your annual cost is tens of thousands. If you are a maintenance agent, your expenses will only cost several thousand yuan.
