Most people do not understand the knowledge points of this article "what skills should be mastered by system operation and maintenance engineers", so the editor summarizes the following contents, detailed contents, clear steps, and has a certain reference value. I hope you can get something after reading this article, let's take a look at this "system operation and maintenance engineers to master what skills" article.

1. The definition of system operation and maintenance.

System operation and maintenance, which refers to Internet operation and maintenance, usually belongs to the technical department, and R & D, testing and system management are the four major departments supported by Internet product technology. this division will be somewhat different at home and abroad, as well as between large and small companies. System operation and maintenance, in essence, is the operation and maintenance of all stages of the life cycle of the network, server and service, and reach an acceptable state in terms of cost, stability and efficiency.

2. The generation of system operation and maintenance.

Great changes have taken place in the Internet in recent decades. From the initial modem dial-up access, it has experienced ISDN access, DSL access, cable modem access, private line access, optical access, wireless access, as well as packet switching network, frame relay network and ATM network. Each technological change represents higher requirements. There are two common modes in the operation of the system, namely, Bhammer S and Cpact S, the server plays a key role, and the operation and maintenance of the system is mainly concentrated on the server, in which the web engine and database engine of the server are very important.

With the rapid development of the telecommunications industry, the business volume of fixed telephone, data transmission, Internet and broadband is growing rapidly, and many troubles are also perplexing telecom operators. The work of network maintenance is becoming more and more onerous, faults can not be tracked, historical failures occur frequently, handling situations, knowledge resources can not be used effectively, at the same time, the handling of faults can not carry out efficiency evaluation and performance evaluation, and such problems give operators a headache. Therefore, how to ensure the normal operation and maintenance of many software and hardware equipment in telecom operators is very important.

3. Skill requirements of system operation and maintenance engineer

(1) maintain various basic / application services, monitor the operation status of hosts / services, ensure the stable operation of business, and ensure the smooth operation of infrastructure.

(2) develop and optimize operation and maintenance solutions, such as disaster recovery, attack prevention, capacity expansion, backup, etc.

(3) be familiar with server performance optimization, promote and develop efficient automatic operation and maintenance and management tools

(4) understand the principles of network and operating system, be proficient in using Shell, and be familiar with at least one language such as Python/PHP/Perl; be able to write efficient operation and maintenance scripts independently

(5) docker,kubernetes related container deployment experience is preferred

(6) familiar with virtualization technology, Kafka, ELK cluster, backup strategy

(7) understand the business knowledge and solutions of operation and maintenance Web system with high capacity, large traffic and large concurrency, and have practical experience in large and medium-sized website maintenance.

There is some hardware driver development (based on x86/ARM).

From the Internet to the Internet of things, the important role of system operation and maintenance in the future will be further highlighted. Operation and maintenance engineers want to do a good job, the premise is always to master hardware driver development skills, while improving the efficiency of operation and maintenance is not limited to existing technology, think hard and love to study technology.

The above is the content of this article on "what skills should system operation and maintenance engineers master". I believe we all have a certain understanding. I hope the content shared by the editor will be helpful to you. If you want to know more about the relevant knowledge, please follow the industry information channel.
