Operation and maintenance services include the operation, maintenance and security protection services of host equipment, operating system, database and storage equipment related to information systems and other information systems, so as to ensure the normal operation of users' existing information systems, reduce the overall management cost and improve the overall service level of network information systems. At the same time, according to the daily maintenance data and records, the overall construction plan and suggestions of the user information system are provided, which better provides a strong guarantee for the user's information development.
The composition of user information system can be mainly divided into two categories: hardware equipment and software system. Hardware devices include network devices, security devices, host devices, storage devices, etc. Software equipment can be divided into operating system software and application software (such as database software and middleware software). ) and commercial applications.
Through the effective management of operation and maintenance services, the service efficiency of user information system can be improved, the internal operation of various business application systems can be coordinated, the communication between network information system departments and business departments can be improved, and the service quality can be improved. Combined with the characteristics of users' existing environment, organizational structure, IT resources and management process, the structure of users' network information system is planned from three aspects: process, personnel and technology. Coordinate the operational objectives and business needs of users with those of IT services.
The goal of information system service is to monitor and manage users' existing information system basic resources, grasp the current situation and configuration information of network information system resources in time, reflect the availability and health of information system resources, and create a controllable IT environment, thus ensuring the reliable, efficient, sustained and safe operation of various business application systems of user information systems.
