First, we start with the job function of the operation and maintenance engineer. The job content of the job:
1. Platform structure establishment
One of the basic tasks of an operation and maintenance engineer is mainly responsible for participating in and reviewing the rationality and operability of the architecture design to ensure that the system runs safely, efficiently and stably after it goes online. Guarantee and continuously improve service availability and data security, and improve user experience.
2. Daily operation guarantee
Primary operation and maintenance is responsible for the use of operation and maintenance technology and operation and maintenance platform to ensure the comprehensive management and full life cycle management of network equipment, and ensure that the status of equipment, business and security can be monitored and controlled. Responsible for formulating emergency plans and organizing drills, responsible for ensuring the stable operation of the business 7*24 hours, and quickly locating and solving various problems that arise during this period.
3. System optimization
Senior operation and maintenance engineers need to consider the optimization of the system. High-level cloud computing operation and maintenance engineers are crucial to the long-term stable operation of the system. Due to the limitations of the Linux server architecture, system failures are inevitable. However, through reasonable design and effective operation and maintenance, the frequency of failures can be greatly reduced and the efficiency of business recovery can be improved.
