Operation and maintenance (Operation and maintenance) generally refers to the maintenance of network hardware and software already established by large organizations, of which the traditional operation and maintenance refers to information technology operation and maintenance (IT operation and maintenance).
The so-called IT operation and maintenance management refers to the unit IT department using the relevant methods, means, technology, systems, processes and documents, etc., on the IT operating environment (such as hardware and software environment, network environment, etc.), IT business systems and IT operation and maintenance personnel to carry out comprehensive management.
With the advancement of the information technology process, operation and maintenance management will cover the entire organization to support the operation of the management information system covers all the contents, in addition to the traditional IT operation and maintenance, but also expand the business operation and daily management operation and maintenance.
The object of its participation from the IT department and personnel, expanding to the organization's management and departments, and its related business backbone. The end result of O&M is the maintenance of the various properties of the software in operation.
Operation and maintenance engineers are divided into several categories from the way they work:
1, operation and maintenance engineers/operation and maintenance development engineers:
Responsible for the specific product line of operation and maintenance work, but also need to master the development of the ability to go deep into the business, the best understanding of the business of the pain point and the problem, and at the same time, research and development/optimization of products for the business demand of the Platforms, tools and means, access to all types of excellent system architecture and the ability to make a comparison of advantages and disadvantages, while the control of the business determines the role of the corresponding operation and maintenance engineers in the development of the business. Long-term development is to become a large-scale system architect.
2, operation and maintenance platform research and development engineers:
Specializing in research and development of operation and maintenance related general platform and technology, need to have a certain product line operation and maintenance experience or from the product line to get the operation and maintenance requirements. Higher requirements for research and development capabilities, the design of the system has a more stringent standards, and can understand user needs, to make a suitable service operation and maintenance to meet the operation and maintenance engineers to use the experience of the operation and maintenance products, the long-term development is to become a technical expert in various technical vertical fields.
3, database R & D engineers / database engineers:
Database direction is a more special direction in the operation and maintenance technology, due to the importance of the business usually need to specialize in the post, the industry in the direction of the deep research and accumulation. The main direction of the database kernel, cloud database, etc., the long-term development is the database field of technical experts, database architects.
4, operation and maintenance manager:
Operation and maintenance students do things in the process usually need to coordinate more than one RD and QA students, the coordination and promotion of the ability to higher requirements for some of the depth of the technology is not bad, the coordination and promotion of the ability to higher students is very suitable for the transition of the management position, the long-term development of the technology sector and the same goal as the management position of the CTO, CEO.
Engineer development in various directions, the main direction is the database kernel, cloud database and so on, the industry is a technical expert in the field of database, database architect. p>Engineers in all directions develop to a certain stage, there is no clear boundaries, need to have a strong operation and maintenance, architecture, programming, algorithms and other capabilities at the same time, is a demanding career.
Expanded Information:
1, solid basic knowledge of computers, including computer system architecture, operating system, network technology, etc.;
2, general application needs to understand the operating system, network, security, storage, CDN, DB, etc., and know the relevant principles;
2, general application needs to understand the operating system, network, security, storage, CDN, DB, etc., and know its
3, programming skills, from the development of operation and maintenance tools to the development of large-scale operation and maintenance systems/platforms need to have good programming skills;
4, data analysis capabilities: the ability to organize, analyze the system's operation of the data, from which to find the problem and find the direction of the solution;
5, a wealth of knowledge of the system, including the system tools, the typical system architecture,
5, rich system knowledge, including system tools, typical system architecture, common platform selection, etc.
6, the ability to comprehensively utilize the tools and platforms;
7, the complexity of operation and maintenance work on the position of operation and maintenance engineers also put forward the requirements of the soft qualities: time management capabilities, especially the ability to deal with the fragmented time; calm mind, the need to face emergencies, the need for change; the ability to communicate, teamwork, and the work of the operation and maintenance of cross-departmental,
