Definition and characteristics of grid service management
Grid service management refers to the use of computer and network technology to integrate resources distributed in different regions, institutions and departments to form a dynamically combined, shared, reusable, on-demand scheduling and efficient service system. It is a service-based, decentralized and distributed management model.
The characteristics of grid service management are as follows: service is the core of grid service management, and service is the basic unit of grid management. Grid service management does not depend on a central node, but realizes service management through collaboration and interaction among nodes distributed in different regions, institutions and departments. The resources in grid service management are distributed on different nodes, which are connected through the network to form a distributed service system. The resources of grid service management are dynamically combined and can be combined according to the requirements. The resources managed by grid service can be reused many times. Grid service management can be scheduled on demand according to demand, which improves the utilization efficiency of resources. Grid service management has high resource utilization efficiency and can improve service quality and efficiency.

Development of Grid Service Management
The idea of grid service management originated in the United States in 1980s, and was widely used in the fields of high-energy physics and computer science. In 1998, the National Science Foundation put forward the concept of grid computing, which marked the formal birth of grid service management.
The development of grid service management has gone through three stages: technical exploration stage, application promotion stage and standardization construction stage.
(1) Technology exploration stage At this stage, the technology of grid service management is mainly explored and studied. At this time, grid service management is mainly used in high-energy physics and computer science to solve large-scale data processing and calculation problems.
(2) Application promotion stage With the development of Internet and computer technology, grid service management has been applied to other fields. At this time, grid service management is mainly used in enterprise management, e-commerce, medical and health fields to improve management efficiency and service quality.
(3) Standardization construction stage With the wider application of grid service management, standardization construction has become an important task for the development of grid service management. At this time, international organizations and standardization organizations began to formulate standards and specifications for grid service management, so as to facilitate interoperability and data sharing between different systems.

The future development trend of grid service management
With the advent of the era of big data, grid service management will face more challenges and opportunities. How to use big data technology to improve the efficiency and quality of grid service management will be an important direction for the future development of grid service management. Cloud computing and grid service management are both important technologies of distributed computing. Integrating them can achieve more efficient computing and data processing, and improve service quality and user experience. The rapid development of artificial intelligence technology provides new ideas and methods for grid service management. Using artificial intelligence technology, we can realize more intelligent service management and more accurate data analysis, and improve service quality and user satisfaction.

Problems in Grid Service Management in The Era of Big Data
In the era of big data, there are some problems in grid service management, including unstable service quality, information security and imperfect service system. Among them, the unstable service quality is characterized by long service response time and unreliable service quality. Information security issues mainly refer to user data leakage, network attacks and other issues; Imperfect service system is characterized by incomplete service scope and inconsistent service standards. In view of these problems, we need to take corresponding countermeasures to solve them, such as establishing a perfect service system, strengthening information security and improving service quality.

Unstable service quality
Because the service providers and users of grid service management are distributed in different regions, the stability of service response time has become a difficult problem. In the era of big data, with the increasing amount of data, the stability of service response time becomes more important. Due to the difference of service providers and service users in grid service management, the service quality varies greatly. Some service providers have high service quality, while others have poor service quality, which will lead to the instability of service quality. In the era of big data, due to the wide distribution of service providers and users, it is difficult to guarantee the reliability of services, which leads to the instability of service quality.
In order to improve the stability of service quality in grid service management, a service quality monitoring mechanism can be established to monitor and manage the service response time, service quality and other indicators, so as to find and solve problems in time and improve the stability of service quality. Strengthen the management of service providers, evaluate and supervise the qualifications and service quality of service providers, improve the service quality of service providers and ensure the stability of service quality. Multi-node backup and fault-tolerant technology are adopted to improve the reliability of service and avoid the instability of service quality caused by single point failure.

Information security issues
Information security is an important issue in grid service management in the era of big data. Because grid service management involves a lot of data exchange and sharing, the information security problem is particularly prominent.
In grid service management, different organizations need to share data, which may contain sensitive information, such as personal privacy and business secrets. If this information is leaked, it will bring immeasurable losses. Therefore, how to ensure the security of data has become an urgent problem.
In grid service management, identity authentication is needed between different organizations to ensure the security and integrity of data. However, there may be fraud in the process of identity authentication, such as impersonating others, which will lead to data tampering or disclosure.
In grid service management, data may be tampered with, thus affecting the reliability and integrity of data. This kind of data tampering may be intentional or unintentional, but in any case, it will pose a threat to the security of data. In grid service management, malicious software may be used to attack the grid service system, resulting in data being tampered with or leaked.
In order to solve the above information security problems, data encryption technology can be strengthened to ensure data security. Multi-identity authentication technology is adopted to ensure the authenticity and integrity of identity. Establish a perfect data integrity detection mechanism to find and correct data tampering in time. Strengthen the prevention and detection of malicious software to ensure the security of the system.

Service system is not perfect
In the era of big data, the service system of grid service management is still imperfect. At present, the service content of grid service management mainly focuses on government, community, medical care and other fields, while the service content in other fields needs to be further improved. At present, grid service management mainly serves urban residents, while rural residents, special groups and other service targets have not been fully concerned. At present, grid service management mainly adopts online service mode, while offline service channels are relatively few, which can not meet the needs of different users.
At present, the policies and regulations of grid service management have not been improved, which leads to the service system can not be effectively standardized and supported. Grid service management has a wide range of service contents and service objects, and needs a lot of resources to support it, but the current resources are still insufficient, which leads to the failure to effectively promote and implement the service system. At present, the technical means of grid service management are not mature enough to meet the needs of different users, which leads to the failure to effectively improve the service system.
The government needs to strengthen policy support for grid service management, formulate corresponding laws and policies, and standardize the construction and implementation of service system. The government and society need to increase the resources investment in grid service management, including human, material and financial support, to ensure the smooth implementation of the service system. The government and enterprises need to strengthen the technical research and application of grid service management, popularize advanced technical means, and improve the efficiency and quality of service system.

Countermeasures for the Problems Existing in Grid Service Management in The Era of Big Data
In the era of big data, the importance of establishing a perfect service system for grid service management and the countermeasures to establish a perfect service system, including the standardization of service processes, the integration and sharing of service resources, the establishment of service evaluation and feedback mechanism, etc. Because the grid service management involves a lot of user information and sensitive data, the occurrence of information security problems may have a serious impact on users and the whole system.
Establishing a perfect information security management system is the basis of ensuring information security. The system should include information security policy, information security organization, information security system, information security technology and information security training. Among them, information security policies should define information security objectives and requirements, information security organizations should establish information security management institutions, information security systems should formulate information security management norms and processes, information security technologies should adopt advanced security technologies and measures, and information security training should strengthen employees' information security awareness and skills training.
Strengthening network security protection is an important means to ensure information security. The measures include strengthening network monitoring, firewall setting, intrusion detection and prevention. Among them, network monitoring can find abnormal situation in time, firewall can prevent illegal intrusion, intrusion detection can find intrusion behavior in time, and preventive measures can prevent information leakage and attacks.
Using encryption technology to protect data security is an important means to ensure information security. The measures include data encryption, transmission channel encryption and user identity authentication. Among them, encrypting the data can protect the confidentiality of the data, encrypting the transmission channel can protect the transmission safety of the data, and authenticating the user identity can ensure the credibility of the system.
Establishing emergency response mechanism is an important means to ensure information security. The mechanism should include emergency plan, emergency drill, emergency response and emergency disposal. Among them, emergency plan can guide emergency response and disposal, emergency drill can improve the efficiency and accuracy of emergency response, emergency response can respond to security incidents in time, and emergency disposal can effectively control the impact of security incidents.
