The editor of Downcodes will elaborate on their respective responsibilities, core tasks and key skills, and analyze the interrelationship and synergy between them to help readers better understand the importance of these three in the stable operation of IT systems. We will explain the respective operation and maintenance work content in detail from the three levels of system, application and hardware, and analyze the skill requirements and career development directions of different operation and maintenance roles.
System operation and maintenance, application operation and maintenance, and hardware operation and maintenance respectively point to different maintenance and management fields in information technology management. System operation and maintenance focuses on the maintenance of the operating system and its components to ensure the stability, security and efficiency of the system. Application operation and maintenance involves the support of applications and is mainly responsible for the deployment, monitoring, optimization and troubleshooting of applications. Hardware operation and maintenance is the maintenance of physical equipment such as servers, storage and network equipment to ensure their good operating status and lifespan.
For example, system operation and maintenance personnel will conduct in-depth research on the operating system's kernel tuning, patch management, and automated script development to improve the overall performance and reliability of the system.
System operation and maintenance, also known as system administrator or system architecture maintenance, is mainly responsible for maintenance work at the operating system level. Its core tasks include operating system installation and configuration, regular system patch updates, system performance monitoring and optimization, and implementation of security protection measures. In addition, system operation and maintenance engineers are also responsible for backup management and disaster recovery plans to ensure data security and reliability.
A core part of system operation and maintenance is system monitoring and performance optimization. By using tools such as Nagios, Zabbix or Prometheus, operation and maintenance engineers can monitor the usage of system resources such as CPU, memory and disk IO in real time. When bottlenecks or exceptions occur, timely tuning or processing is performed, such as adjusting system parameters, adding resources, or expanding clusters, to ensure the smooth operation of the system.
System operation and maintenance also includes the management of operating system level security measures. This means installing and updating antivirus software, managing firewall rules, handling security breaches, and implementing data encryption and access control policies. Compliance enforcement is also an important part of system operation and maintenance, especially in industries involving sensitive data, such as medical and finance.
Application operation and maintenance mainly focuses on application-level operation and maintenance work, including but not limited to application deployment, configuration management, monitoring, log analysis, performance tuning, troubleshooting, and user support. Application operation and maintenance needs to work closely with the development team to ensure the stable and efficient operation of the application; at the same time, it needs to make appropriate application adjustments and optimizations based on user feedback.
A key task of application operation and maintenance is to implement automated deployment processes. Through continuous integration/continuous deployment (CI/CD) tool chains, such as Jenkins and GitLab CI/CD, automated testing, building and deployment of applications can be achieved, greatly improving deployment efficiency and frequency, while reducing human errors.
Whether it is internal users or external customers, application operations and maintenance need to respond to their problems and provide effective solutions in a timely manner. Operation and maintenance engineers will use log analysis tools such as ELK Stack or Splunk to locate and troubleshoot application problems. Continuous performance monitoring and optimization are also important aspects to ensure application stability.
Hardware operation and maintenance focuses on physical maintenance work, including hardware resources such as servers, network equipment, and storage devices. The responsibilities of hardware operation and maintenance engineers cover the selection, installation, monitoring, troubleshooting and replacement of hardware equipment to ensure that the physical equipment in the data center operates worry-free and serves the entire IT architecture as expected.
Monitoring is an extremely critical part of hardware operation and maintenance. Using tools such as SNMP and IPMI, hardware status and environmental parameters such as temperature, humidity and power status can be monitored in real time. When anomalies are detected, respond promptly, such as replacing faulty hardware or adjusting the data center environment to avoid possible service interruptions.
Hardware operation and maintenance engineers not only ensure the daily operation of the equipment, but also plan and manage the entire life cycle of the equipment. This includes selection, procurement, maintenance, asset management and retirement. Through rigorous life cycle management, optimal utilization of assets and optimization of total cost of ownership (TCO) can be ensured.
To sum up, although system operation and maintenance, application operation and maintenance, and hardware operation and maintenance focus on different areas, they complement each other in maintaining the healthy operation of the entire IT system. System operation and maintenance ensures the stability and security of the operating system, application operation and maintenance ensures the efficiency and reliability of application services, and hardware operation and maintenance is responsible for the normal operation of hardware devices. In today's enterprise IT operations management, these three are indispensable.
