What does operation and maintenance do?

Operation and maintenance refers to the operation and maintenance of the network software and hardware established by large institutions. So what is the specific operation and maintenance? Look at the relevant information with me, hoping to bring help to everyone.

What is operation and maintenance? This refers to Internet operation and maintenance, which usually belongs to the technical department. Together with R&D, testing and system management, Internet products are supported by four major departments. This division will be somewhat different between domestic and foreign companies and between large and small companies.

The general process of an Internet product is: product manager, demand analysis, R&D department development, testing department testing, operation and maintenance department deployment and release, and long-term operation and maintenance.

Operation and maintenance is essentially the operation and maintenance of networks, servers and services at all stages of the life cycle, which is in an acceptable state in terms of cost, stability and efficiency.

What does an operation and maintenance engineer do? 1. Problem discovery: design and develop an efficient monitoring platform and alarm platform, and use machine learning, big data analysis and other methods to summarize and analyze a large number of monitoring data in the system, so as to quickly find problems when the system is abnormal and judge the impact of faults.

2. Problem handling: Design and develop an efficient problem handling platform and tools, which can quickly/automatically make decisions when the system is abnormal, trigger relevant stop-loss plans, and quickly restore services.

3. Problem tracking: Determine the root cause of the problem by analyzing various manifestations (logs, changes and monitoring) of the system when the problem occurs, and formulate and develop the pre-plan tool.

4. Change management: complete the iterative change of product functions as efficiently as possible in a controllable way. The main work in this area includes:

5. Configuration management: Manage the relationship between multiple modules and versions involved in the service and the accuracy of configuration through configuration management platforms (self-developed and open source).

6. Release management: build an automation platform to ensure that each version change can be released to the production environment safely and controllably.

7. Capacity management: In the service operation and maintenance stage, in order to ensure the rationality of service architecture deployment and grasp the redundancy of the whole service, it is necessary to continuously evaluate the carrying capacity of the system and continuously optimize it. The main work in this area includes:

The starting salary of an operation and maintenance engineer in January is usually 8- 10K, 1-3 years' working experience can reach 12- 16K, and 3-5 years' working experience can get an annual salary of 30-50W. There is a great demand from major manufacturers, and the salary is no less than that of programmers. Although it is more likely that the monthly salary of Internet technology posts will exceed 10,000 yuan, the demand for the Internet is no longer the operation and maintenance of a single skill, but really favors talents engaged in operation and maintenance+development, and the salary is naturally higher than that of ordinary operation and maintenance.

In the gradual development stage, engineers who pay attention to summarization and introspection will gradually grow into high-level operation and maintenance personnel, and usually have a more systematic understanding of business operation and maintenance. There are also some engineers who gradually become project managers because of their excellent project management planning ability. Further development, high-level operation and maintenance personnel will have a thorough understanding of the product, so in this case, high-level operation and maintenance personnel can even become product managers and product research and development consultants, and play a vital role in the design and development of product functions.

Engineers in all directions need to have strong ability in operation and maintenance, architecture, programming, algorithm and so on, which is a demanding profession. In the future, the quality of operation and maintenance engineers will be higher and higher, and the specifications will be stronger and stronger.
