What exactly is Linux operation and maintenance? Do you really fix computers?
When it comes to operation and maintenance engineers, most people think that they repair computers. In fact, the work of an operation and maintenance engineer is not so simple. Operation and maintenance literally means that operation is operation, and maintenance is maintenance, so the function of operation and maintenance engineer is to ensure the normal operation of the business and maintain it in time when problems occur.
Use professional terms to explain that the operation and maintenance engineer is responsible for maintaining and ensuring the high availability of the entire service system, while continuously optimizing the system architecture to improve deployment efficiency, optimizing resource utilization and improving the overall ROI. Operation and maintenance engineer is a general term, and there are many categories in it. Including: desktop operation and maintenance engineers, network operation and maintenance engineers, system operation and maintenance engineers, basic operation and maintenance engineers, etc., their division is mainly based on the specific content of the work. Let's take a look at what operation and maintenance engineers do with Qianfeng Guangzhou Xiaobian!
What does Linux operation and maintenance do?
Simply put, it is to maintain the normal operation of the Linux system and related software services, program codes (Java, Php, Python) and enterprise core data on the system, so that the enterprise can provide high-quality, efficient and fast services for the enterprise's customers, thereby Profits make money. With the growth of the enterprise, the number and requirements of servers and services will also increase exponentially, and there will be more requirements for the ability of operation and maintenance and the number of operation and maintenance personnel.
In the operation of the entire enterprise business system, personnel with integrated technologies such as system, network, database, storage, development, security, monitoring, and architecture are involved, so higher requirements are placed on the ability of operation and maintenance personnel.
What are the roles of Linux operation and maintenance?
Hardware operation and maintenance: hardware maintenance, such as servers, switches, routers, storage, load balancing and other equipment;
Network operation and maintenance: network equipment maintenance: maintenance of switches, routers and office LANs;
System operation and maintenance: The maintenance of infrastructure, focusing on systems and applications, also involves hardware networks;
Application operation and maintenance (SRE): maintenance and troubleshooting of enterprise business R&D environment, test environment, online environment, etc.;
Monitoring operation and maintenance: monitoring and alarming the business of all server clusters in the entire business system;
Database operation and maintenance: responsible for data storage scheme design, database table design, index design and SQL optimization;
Security operation and maintenance: security scanning, penetration testing, security tools, emergency handling of security incidents, etc.;
Operation and maintenance development: development of operation and maintenance tools and platforms, as well as intelligent and automated operation and maintenance;
Operation and maintenance engineers also include some low-end positions, such as: network administrator, monitoring operation and maintenance, IDC operation and maintenance, on-duty operation and maintenance, etc. The development of these positions is limited and needs to be promoted as soon as possible to obtain better development opportunities.
