What is operation and maintenance

Operation and maintenance is a job that requires high knowledge. It requires IT outsourcing operators not only to understand basic system and network knowledge, but also to have an in-depth understanding of the business system for operation and maintenance, and to understand the working mode of the entire business system. with the working principle. This is also a test of the learning ability of IT operation and maintenance personnel. As soon as you hear the failure description, you can get a general idea of where the problem is. At the same time know how to identify and solve problems through technical means and clear logical methods.

Operations is a job that requires a high degree of automation. With the continuous development of IT technology, more and more technologies that facilitate operation and maintenance emerge as the times require. Since the Internet era, the delivery and iteration of business systems have become more and more frequent, from once a month to scenarios that are repeated multiple times a day. If there is no automated means to quickly respond and process, the impact on users can be imagined.

Mainstream technology:

Operation and maintenance personnel must have certain exposure to current mainstream technologies (cloud computing, edge computing, big data, AIops, artificial intelligence, deep learning, etc.) and must keep pace with the times. Often participate in online or offline related discussions and exchange learning. Understand the current popular IT technology, learn it, think about how to use it in the business of the enterprise, create value for the enterprise, and improve the efficiency of operation and maintenance. Therefore, the ability to capture mainstream technologies is also one of the required courses for operation and maintenance personnel.

monitor

As the saying goes, it is better to take precautions than to regret the past. The purpose of monitoring is to prevent problems before they occur. Through monitoring, operation and maintenance personnel can keep abreast of the running status of the enterprise network. Once a security risk occurs, the operation and maintenance personnel can be warned in advance or notified in other ways, so that the operation and maintenance personnel have time to deal with and solve the problem and avoid affecting the business system. Normal usage will kill the root cause of all problems in Gradle. There are many ways to monitor and more software. How to select monitoring objects and design monitoring indicators requires operation and maintenance personnel to practice according to the actual situation of different businesses. But keep in mind that current monitoring tools can automatically fix some failures when monitoring metrics are triggered, but at best they can only help you with simple automated tasks. Higher-level automation tasks require operators to have more in-depth scripting and system knowledge.

Therefore, as the eyes of IT operation and maintenance personnel, monitoring must always maintain the spirit of 12 o'clock. Operation and maintenance personnel should regularly "care" the monitoring system to avoid "visual fatigue" and affect the monitoring effect.

backup

As the saying goes, there are unforeseen circumstances in the sky, and man-made disasters and blessings have come recently; backup is a security mechanism, which is generally not used, but it is a major event when it is used. Backup can be said to be the last straw for operation and maintenance personnel. If you use this last straw well, you can come back to life. If you don't use it well, you will die without a burial place. In fact, this is not an exaggeration at all. The company entrusts heavy assets to operation and maintenance, which is the trust in operation and maintenance. Operation and maintenance personnel are naturally responsible for these assets and data, and responsible for the company. This is also the embodiment of the value of operation and maintenance. .

Now there are many backup software, both at home and abroad, so it is very important to choose a backup software that suits your business needs. Not all data needs to be backed up. First, determine which data needs to be backed up and determine the scope of the backup. Develop a backup strategy. Different data requires different policy settings. To choose a reliable backup medium, whether to choose tape, hard disk or optical medium, etc., all these need to be formulated by operation and maintenance personnel according to business needs.

Summarize

The above is a small summary of my own operation and maintenance experience in the past ten years. A lot of content can't be written in a day, and it's impossible to write all of it. After all, many operations and maintenance things rely on their own perception and intuition. In the chapter on operation and maintenance methods, I just summarize

It combines some of the main methods used in its own operation and maintenance, and does not involve specific technologies. Some friends may ask why the popular CMDB, visual operation and maintenance, ITSM, etc. are not reflected. In fact, these are just tools, an operation and maintenance tool, which makes operation and maintenance more transparent, easier for operation and maintenance personnel, and more assured for the boss. In actual work, you can buy or develop it yourself as needed to meet your business needs. Finally, I shared with my friends in operation and maintenance, "Operation and maintenance is a meticulous job, and sloppy work is not allowed. Operation and maintenance personnel must have an innovative spirit and work enthusiasm. With these things, I believe that you must be a very good person. Good operation and maintenance person."
