How to view the Chinese content in Wireshark packet capture content

The following are the views of some senior operation and maintenance engineers in China's Internet industry on operation and maintenance (privacy is involved, and the acronyms of the relevant names are used):

CXY:

Operation and maintenance is a very broad definition, and different companies have different responsibilities and positions at different stages. If you understand the literal meaning of operation and think that it is just a job of typing a few lines of operation commands, you would be wrong. For a start-up company, the work of an operation and maintenance engineer may start from applying for a domain name, purchasing/renting a server, launching it, adjusting the settings of network equipment, deploying the operating system and operating environment, deploying code, designing and deploying monitoring, preventing vulnerabilities and attacks, etc. . For large companies, the requirements for operation and maintenance work are getting higher and higher, which has also given rise to a more detailed division of operation and maintenance: from a broad perspective, it can be divided into website operation and maintenance, system operation and maintenance, network operation and maintenance, and database operation and maintenance. , IT operation and maintenance, operation and maintenance development, operation and maintenance security and other directions.

Many non-practitioners’ 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 a few points of operation and maintenance work: deployment, change, monitoring, and response.

No matter what operation and maintenance is done, the most basic responsibility is to ensure that the business can run stably. So you must become the owner of business stability. Some people usually think that operation and maintenance engineers are like firefighters, responding to abnormalities and putting out fires 24/7. But the careers of stability operation and maintenance engineers are closer to those of doctors. Doctors are also divided into various departments, including emergency departments. They need to first determine the patient's problem and prescribe the right medicine.

Businesses have various needs. If operation and maintenance engineers can meet business needs, or proactively explore business pain points and improvement methods, they can achieve more value for the business.

When meeting business needs, we should prioritize and prioritize the very important needs for rapid business development, such as stability, deployment and change efficiency, and capacity management. Needless to say, stability. If users cannot use your business stably, any product features will be of no value. For a rapidly developing Internet company like Baidu, a large number of upgrades and updates need to be provided to users every day. How to meet the product upgrade needs as quickly as possible on a large remote cluster while making users unaware of the upgrade process is our goal. Pursue. When users use Baidu to measure whether the network can access the Internet, it is a compliment to the quality of operation and maintenance.

Secondly, you can look at the needs of different businesses horizontally. If we can abstract the needs of multiple businesses and turn some universally valuable work platforms into platforms (such as databases, CDNs, monitoring, traffic access and scheduling, big data storage and computing), we can also conduct in-depth research in this direction. develop. With Baidu's huge traffic and server scale, you not only have huge space and challenges, but also have sufficient resources and support to develop and apply the most cutting-edge technologies in the industry.

After a certain amount of accumulation, you can enter the macro and micro levels and consider the intelligent deployment and scheduling of business from the entire company level (involving various points such as network, hardware, system, application development methods, etc.) , to further improve efficiency and save costs.

If you can understand the business, understand the business model, and closely integrate the business to optimize and innovate, this is another way for operation and maintenance engineers to reflect their value. There are many product innovations, patent applications, paper publications, and improvement of business indicators, all contributed by operation and maintenance engineers directly or in a cooperative manner.

YBX:

Compared with R&D personnel, operation and maintenance engineers can globally observe the computer system being maintained, especially high-level operation and maintenance engineers. There are no module boundaries. This is unique. The location brings a lot of value: knowing the accurate bottleneck point of the system, and thus knowing the accurate capacity of the system; knowing how to quickly provide capacity before the system bottlenecks. Knowing the risk points of the system, you can coordinate the related modules above and below the risk points to make redundant strategies; it is more reasonable than focusing on solving the stability of single-point modules. Having been engaged in related work for a long time, I have accumulated a lot of experience in architecture design and can guide the design and review of new architectures. From the perspective of the company's different businesses, operations and maintenance can abstract the same modules and manage them in a unified manner to form an effective platform and automated management methods. Similarly, from the perspective of the company's different businesses, resources can be allocated in a unified manner, thereby saving resources.

KZ: Design and implement software that improves the availability, scalability, latency and efficiency of company services. Handle daily emergencies, correct, and replace problematic components. and devise ways to avoid problems. Design and implement new hyperscale distributed system architectures and standards. Participate in service expansion plans and predict service growth trends, and tune software and system performance. Provide online consulting services and on-site problem solving services. Build an automatic operation and maintenance platform to solve daily problems. Build a knowledge base and predict possible problems. XX:

Operation and maintenance refers to the entire process of maintaining the production environment and the resources and services related to the production environment, including relevant technologies and process means to ensure the stable, efficient and low-cost operation of the production environment.

On the one hand, operation and maintenance is ultimately responsible for business functions, and its value is reflected in maximizing product value. This is usually achieved by maximizing the performance of product features. For example, the focus of search engine operation and maintenance is to ensure the ultimate user experience when searching: stable, fast, accurate, new, and comprehensive. The operation and maintenance of an online chat system should ensure the real-time and smooth user chat process. On the other hand, you are ultimately responsible for the costs of your online business. Its value is reflected in the reduction of service operation costs

The way in which operation and maintenance work is carried out generally depends on the characteristics of the business being maintained, forming the required multiple theme directions for development. Common solutions include the following subject directions: event management, configuration management, change management, capacity management, etc.

The requirements for operation and maintenance engineers are particularly strict, because operation and maintenance engineers need to constantly supplement and expand their knowledge and research scope for different problems.

In the early stage, excellent operation and maintenance engineers will show outstanding initiative and sense of responsibility. When faced with unfamiliar business, they will take the initiative to learn and expand their understanding of the business and the corresponding knowledge scope, so as to be able to Sufficiently competent in independent maintenance of the business.

In the gradual development stage, engineers who focus on summary and introspection will gradually grow into high-level operation and maintenance engineers, and usually they will have a more systematic understanding of service operation and maintenance. There are also some engineers who have gradually become project managers due to their excellent project management and planning skills

With further development, high-level operation and maintenance engineers will have a very thorough understanding of the product. Therefore, in this case, high-level operation and maintenance engineers will have a very thorough understanding of the product. Level operation and maintenance engineers can even become product managers and product development consultants, playing a vital role in the design and development of product functions.
