IT Operations and maintenance: Full life cycle management from basic support to business empowerment

IT Operations Management (ITOM) is the core link that ensures the stable operation of an enterprise's IT systems (covering hardware, software, networks, data, etc.) and efficiently supports business operations. IT runs through the entire life cycle of the system, from deployment, daily monitoring to fault handling, optimization and upgrading. As IT architecture evolves from traditional physical machines to cloud-native and hybrid clouds, IT operations and maintenance have gradually upgraded from "passive response to faults" to "active risk prediction" and "intelligent autonomous optimization". The core goal has always been to reduce system failure rates, improve operation and maintenance efficiency, and ensure business continuity, ultimately providing reliable technical support for the growth of enterprise business.

Infrastructure serves as the operational foundation for IT systems. The core of operation and maintenance is to ensure the stable availability of hardware devices and virtual resources. Specific tasks include:

Hardware equipment operation and maintenance: Responsible for the deployment, daily inspection and fault repair of servers, storage devices (such as disk arrays), and network devices (switches, routers, firewalls). For instance, regularly check the CPU temperature and memory usage rate of the server, and replace faulty hard disks in a timely manner. Investigate the issue of network link interruption to ensure smooth cross-departmental data transmission.

Virtualization and cloud resource operation and maintenance: For virtualization platforms such as VMware and KVM, as well as public cloud resources like Alibaba Cloud, AWS, and Huawei Cloud, perform instance creation, resource scheduling, and elastic expansion. For instance, expand the cloud server instances before major e-commerce promotions to prevent system lag caused by peak traffic. Optimize the resource allocation of K8s cluster nodes to reduce idle resources.

Computer room environment operation and maintenance: Monitor the temperature and humidity of the computer room (maintained at 18-27℃ and 40%-60% humidity), power supply system (such as UPS uninterruptible power supply), and fire protection system (gas fire extinguishing devices, smoke detectors) to prevent equipment damage caused by extreme environments or power outages, fires and other risks. For instance, during the rainy season, check the waterproofing of the computer room and regularly test the battery life of the UPS.
