How to be a qualified operation engineer? what is the prospect of operation and maintenance engineer? I would like to communicate with you on these issues. First of all, the requirements of operation and maintenance engineers are very stringent, operation and maintenance engineers not only have to respond to different problems, but also need to constantly supplement their own knowledge, and do not continue to improve their own. Keep pace with the times and keep learning new technologies.

In the initial stage of operation and maintenance engineers, qualified and excellent operation and maintenance personnel should show positive initiative and sense of responsibility, and should take the initiative to quickly learn business understanding and expand the corresponding scope of knowledge in the face of unfamiliar business. in order to be competent enough and do independent maintenance. At this stage, the basic knowledge should be very solid, and constantly enrich their own. Form your own knowledge system.

In the gradual development stage of operation and maintenance, operation and maintenance engineers should pay attention to summary and reflection, and gradually grow into high-level operation and maintenance engineers, senior operation and maintenance engineers, they will have their own more systematic understanding of operation and maintenance. This is also the reason why some operation and maintenance engineers have gradually grown into project managers because of their excellent ability in all aspects of project management.

With the further development, high-level operation and maintenance engineers will have a thorough understanding of all aspects of the product, so in this case, senior operation and maintenance engineers can even become excellent product managers and play a very important role in the design and development of product functions.

Qualified operation and maintenance engineers are responsible for maintaining and ensuring the high availability of the entire service system, while constantly optimizing the system architecture, improving deployment efficiency, optimizing resource utilization, and improving the ROI of the overall system. It's easy to say, it takes a lot of knowledge to accumulate. With the rapid development of technology, operation and maintenance engineers are facing more and more challenges. The management of large-scale clusters is one of the most intractable problems. How to manage the services of tens of thousands or even hundreds of thousands of servers while ensuring the high availability of services is one of the biggest challenges faced by operation and maintenance personnel.

The work of operation and maintenance engineers is becoming more and more important in large Internet companies. With the increasing scale of the Internet and the increasing complexity and diversity of the service structure, the demand for operation and maintenance engineers will become more and more urgent, which is good news for people who are engaged in or are about to engage in the operation and maintenance industry. In particular, there will be a great demand for experienced operation and maintenance engineers, and it will become more and more valuable with the accumulation of experience. An excellent operation and maintenance engineer, has a strong sense of responsibility and initiative, owner awareness of the work he is responsible for, and can self-drive to continue to learn and grow. And be able to work under great pressure and have strong ability to analyze and solve problems independently. Be bold and cautious in your work, and have the spirit of exploration and innovation. At present, all positions require proficiency in at least one of the languages such as shell/Python/Perl. It is also necessary to master a variety of commonly used databases and be able to use them flexibly. There is also the most basic basic knowledge of collaterals, which is also indispensable. The Linux-like operating system must be deeply understood. You know, most of the current servers are based on the linux operating system. Here we can recommend a basic textbook "this is how to learn linux". It is very suitable for beginners to enter linux system.

For operation and maintenance engineers, risk identification is the top priority at present. Risk identification means that before the risk accident occurs, or when operating some actions, as an operation and maintenance engineer, we should use various methods to systematically and continuously understand the various risks faced, and analyze the potential causes of the risk accident. Draw up the risk management plan in time, carry on the risk management decision service. Avoid risk or minimize risk. Think about it before you do something. All kinds of situations, the worst-case scenario. Analysis and evaluation. Whether the measures to deal with the risk can be grasped. I can't control it. Don't operate it.

Now devops has entered more and more enterprises. What is devops? Devops is not an automatic operation and maintenance.

DevOps (combination of Development and Operations) is a group of processes, methods and systems that facilitate communication, collaboration and integration among development (application / software engineering), technology operations and quality assurance (QA) departments, and make software construction, testing and release faster, more frequent and reliable through highly automated tools and processes. This puts forward the highest requirements for operation and maintenance engineers. In the process of software development, the code is frequently continuously integrated into the trunk and tested automatically. (focus on automated testing). On the basis of continuous integration, deploy the integrated code to the test environment (real running environment, grayscale environment), even the library environment for more testing, ok, manual deployment to production. Automate the process of deployment to the production environment on the basis of continuous delivery. The difference is that the final deployment to the production environment is automated. This puts forward higher requirements for operation and maintenance engineers.

Children's shoes who are about to engage in operation and maintenance work or are engaged in operation and maintenance work. Let's share it.
