What does operation and maintenance do?

Operation and maintenance is a very broad definition, which has different responsibilities and positioning in different companies at different stages. If understood from the literal meaning of the operation, it is wrong to think that it is the work of typing a few lines of operation orders. For a start-up company, the work of an operation and maintenance engineer may need to start from applying for a domain name, buying/renting servers, putting servers on shelves, adjusting network equipment settings, deploying operating systems and running environments, deploying codes, designing and deploying monitoring, and preventing vulnerabilities and attacks. For large companies, the requirements for operation and maintenance work are getting higher and higher, which also gives birth to a more detailed division of labor: generally speaking, IT can be divided into website operation and maintenance, system operation and maintenance, network operation and maintenance, database operation and maintenance, IT operation and maintenance, operation and development, operation and maintenance security and other directions.

Many non-employees' views on operation and maintenance generally belong to a very small responsibility of IT operation and maintenance: installing the system. Some R&D engineers' views on operation and maintenance are limited to several points: deployment, change, monitoring and response.

No matter what operation and maintenance, the most basic duty is to ensure the stable operation of the business. So it must be a stable owner of the business. Some people usually think that operation and maintenance engineers are like firefighters, who react abnormally for 7*24 hours and put out fires. But the stable operation engineer is closer to the profession of doctor. Doctors are also divided into various departments and emergency rooms. We must first judge the patient's problems and prescribe the right medicine.

Enterprises have various needs. If the operation and maintenance engineers can meet the business needs or actively explore the pain points and improvement methods of the business, they can realize more value for the business.

When meeting business needs, we should prioritize and give priority to the very important needs of rapid business development, such as stability, deployment and change efficiency, capacity management, etc. Needless to say, stability, if users can't use your business stably, any product function is worthless. For a fast-growing Internet company like Baidu, there are a lot of upgrades to be provided to users every day. How to meet the needs of product upgrading in large clusters in different places at the fastest speed, and at the same time let users not know the upgrading process, is our pursuit. When users will use Baidu to measure whether the network can get online, it is a praise for the quality of operation and maintenance.

Secondly, we can look at the needs of different businesses horizontally. If we can abstract the requirements of various services and platformize some work with universal value (such as database, cdn, monitoring, traffic access and scheduling, storage and calculation of big data), we can also develop in this direction. With the huge traffic and server scale like Baidu, you not only have huge space and challenges, but also have enough resources and support to develop and apply the most cutting-edge technologies in the industry.

After a certain accumulation, we can enter the macro and micro level, and consider the intelligent deployment and scheduling of services from the whole company level (involving key points such as network, hardware, system and application development mode), so as to further improve efficiency and save costs.

If you can understand the business, understand the business model, and combine it closely with the business to optimize and innovate, it is another way for the operation and maintenance engineer to reflect the value. There are many product innovations, patent applications, papers published and business indicators improved, all of which are directly or cooperatively contributed by operation and maintenance engineers.

Job content of operation and maintenance engineer

In the whole life cycle of software products, operation and maintenance engineers need to participate in and play different roles in time, so the work content and direction of operation and maintenance engineers are very many: event management: the goal is to restore services as quickly as possible when services are abnormal, thus ensuring the availability of services; At the same time, in-depth analysis of the causes of the failure, upgrading and repairing the problems existing in the service, designing and formulating relevant programs to ensure efficient stop loss when the service fails. The main work in this area includes: problem discovery: designing and developing efficient monitoring platform and alarm platform, and summarizing and analyzing a large number of monitoring data in the system by using machine learning, big data analysis and other methods, so as to quickly find problems when the system is abnormal and judge the impact of faults. Problem solving: design and develop efficient problem solving platforms and tools, which can make decisions quickly/automatically when the system is abnormal, trigger relevant stop-loss plans, and quickly restore services. Problem tracking: By analyzing various manifestations (logs, changes and monitoring) of the system when the problem occurs, the root cause of the problem is determined, and the pre-plan tool is formulated and developed. Change management: In a controllable way, complete the iterative change of product functions as efficiently as possible. The main contents of this operation include: configuration management: managing 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). Release management: build an automated platform to ensure that each version change can be released to the production environment safely and controllably. Capacity management: In the stage of service operation and maintenance, 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: capacity evaluation: simulating the actual user request through technical means and testing the maximum throughput that the whole system can withstand; By establishing a capacity evaluation model, the data in the stress test process are analyzed to evaluate the capacity of the whole service. Capacity optimization: according to the capacity evaluation data, judge the system bottleneck and provide capacity optimization solutions. For example, by adjusting system parameters and optimizing service deployment architecture, the system capacity can be effectively improved. Architecture optimization: In order to support the continuous iteration of products, it is necessary to continuously optimize and adjust the architecture. To ensure that the whole product can maintain high availability under the condition of constantly rich and complex functions.
