What does O&M do?
Operation and maintenance is a very broad definition, in different companies at different stages have different responsibilities and positioning, if the OPERATION literal meaning to understand, that is, knocking a few lines of operation command work, that would be wrong. For startup companies, the work of the operations engineer may need to start from applying for a domain name, purchase / rent a server, on the shelf, adjust the network equipment settings, deployment of operating systems and operating environments, deployment of code, the design and deployment of monitoring, to prevent vulnerabilities and attacks, and so on. For large companies, for the operation and maintenance of the work of the requirements of more and more high, but also gave birth to a more refined operation and maintenance of the division of labor: from the direction of the big, 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 maintenance of the development of operation and maintenance of the direction of the security and so on.
A lot of non-practitioners on the operation and maintenance of the view generally belongs to the IT operation and maintenance of a very small duties: load system ^^. Some R&D engineers have a limited view of O&M as a few points: deployment, change, monitoring, and response.
Regardless of what you do in O&M, the most basic responsibility is to ensure that the business can run stably. So you have to be the owner of the business stability. some people usually think that O&M engineers are like firefighters, responding to anomalies and putting out fires 24 hours a day. But the stability of the operation and maintenance engineers and doctors are closer to the profession. Doctors are also divided into various departments, there is also an emergency room, you need to first determine the patient's problem, the right medicine.
The business has a variety of needs, if the operations engineer can meet the business needs, or take the initiative to dig the pain points of the business and improve the method, you can realize more value for the business.
When meeting business needs, you should prioritize and prioritize the needs that are important to the rapid development of your business, such as stability, deployment and change efficiency, and capacity management. If users can't use your business stably, any product features are worthless. For Baidu, which is a fast-growing Internet company, there are a lot of upgrades and updates that need to be provided to users every day, so it is our pursuit to meet the fastest product upgrade requirements on a large cluster in an off-site location, and at the same time, make users imperceptible to the upgrade process. When users will use Baidu to measure whether the network can access the Internet or not, it is a compliment to the quality of operation and maintenance.
Second, you can look horizontally at the needs of different businesses. If you can abstract the needs of multiple businesses and platformize some of the work that has common value (e.g., database, cdn, monitoring, traffic access and scheduling, storage and computation of big data), you can also go deeper in this direction. With such a huge traffic and server scale as Baidu, you not only have a huge space and challenge, but also enough resources and support to develop and apply the most cutting-edge technologies in the industry.
With a certain amount of accumulation, you can go to both the macro and micro levels, and consider the intelligent deployment and scheduling of business from the whole company level (involving various points such as network, hardware, system, and the way of application development), to further improve the efficiency and save the cost.
If you can understand the business, understand the business model, and closely integrate with the business to optimize and innovate, it is also another way to reflect the value of the operation and maintenance engineers. There are a lot of product innovations, patent applications, papers published, and business metrics improved, directly or in a collaborative way, by O&M engineers.

The work of O&M engineers
O&M engineers need to be involved and play different roles in the entire software product lifecycle at the right time, so the work of the O&M engineers is very varied: event management: the goal is to restore the service as quickly as possible in the event of service anomalies, so as to ensure service availability; at the same time, in-depth analysis of the causes of the failure, to promote and protect the service, and to ensure that the service is available for use. In-depth analysis of the causes of failure, to promote and repair the problems of the service, and at the same time to design and develop relevant plans to ensure that the service failure can be efficient stop-loss. The main tasks in this area are as follows: Problem discovery: design and develop efficient monitoring platforms and alert platforms, use machine learning, big data analysis and other methods to summarize and analyze a large amount of monitoring data in the system, so as to quickly discover the problems and determine the impact of failures when the system is abnormal. Problem Handling: Design and develop efficient problem handling platforms and tools to quickly/automatically make decisions and trigger relevant stop-loss plans to quickly restore services when system anomalies occur. Problem tracking: Determine the root cause of the problem by analyzing the system performance (logs, changes, and monitoring) when the problem occurs, and formulate and develop tools to prevent the problem. Change Management: To complete the change work of product function iteration as efficiently as possible in a controllable way. In this regard, the main work of the operation are: Configuration management: through the configuration management platform (self-research, open source) to manage the service involves multiple modules, multiple versions of the relationship and the accuracy of the configuration. Release Management: Ensure that every version change can be released to the production environment in a safe and controlled manner by building an automated platform. Capacity Management: In the service operation and maintenance phase, in order to ensure the reasonableness of service architecture deployment while mastering the overall redundancy of the service, it is necessary to constantly assess the system's carrying capacity and continuously optimize it. In this regard, the main tasks are as follows: Capacity assessment: simulate actual user requests through technical means to test the maximum throughput that the whole system can bear; analyze the data in the stress test process to assess the capacity of the whole service through the establishment of a capacity assessment model. Capacity Optimization: Based on the capacity assessment data, determine the bottleneck of the system and provide capacity optimization solutions. For example, by adjusting system parameters, optimizing service deployment architecture and other methods to efficiently improve system capacity. Architecture optimization: In order to support the continuous iteration of the product, it is necessary to continuously optimize and adjust the architecture. To ensure that the entire product can be in the function of continuous enrichment and complexity of the conditions, while maintaining high availability.
