Administration. Correlation between system and network administration

AdministrationPurpose

Story system administration dates back several decades. Due to the dominant host-terminal architecture of the 1980s, the organization of administrative software was also centralized. In the 90s, the rapid spread of the client-server architecture led to dramatic changes: instead of monitoring a homogeneous environment, the administrator needed to solve many problems: accounting for resource distribution, license control, load redistribution, etc.

From the point of view of the tasks being solved, when mainframes predominated, their administration could be classified as system administration. With the advent of distributed architecture, management tasks were limited to overseeing the functioning of individual components. System administration includes:

Solving problem situations

Resource Management

Configuration management

Performance monitoring

Data management

Network Administration arose when administrators had the ability to manage the image of the entire network. For some time, network administration began to be considered as the main concern of IS administrators, which did not quite correspond to the logic of the functioning of the CIS, because the network plays the role of just infrastructure. Network administration includes:

Work control network equipment

Managing the functioning of networks as a whole

When the number of distributed applications exceeded a certain threshold, the process of integrating system and network administration became inevitable. Network administration began to be viewed as a component of system administration, and the network as one of the managed resources.

Administration. Network Administration

Administration– these are management procedures that regulate some processes or part of them. These processes include work planning, construction, operation and support of an effective IT infrastructure integrated into the overall architecture of the information system. Purpose administration is to achieve such parameters for the functioning of the IS that would meet the needs of users.

Network administration includes:

Monitoring the operation of network equipment– monitoring of individual network devices, setting and changing their configuration, troubleshooting. Also called reactive control.

Managing the functioning of networks as a whole– monitoring network traffic, identifying trends and analyzing events to proactively prevent network problems. It uses a single view of the network to make changes to the network, accounting for network resources, managing IP addresses, and packet filtering. Also called preventive administration.

The most common architecture is manager-agent. The manager runs on the management console and constantly interacts with agents on network devices. Agents collect local data about the operating parameters of a network device.

Currently, a three-level scheme is used: part of the control is delegated to the most important network nodes. Manager programs are installed in the nodes, which, through their own network of agents, control the operation of the devices, and themselves are agents of the central manager. Local and central managers interact only when necessary.

The network software industry is divided into three parts:

Network Management Platforms

Control applications from network hardware manufacturers

Third party software aimed at solving narrow network administration tasks

Currently, no organization can do without computers, which are usually connected to a common local network. That is why the correct functioning of the entire computer “web” is considered vital in order for any company information systems to correctly and fully perform their functions, and administration local network in this case, it becomes the main task for organizations of any structure and scale.

The service for administering computer networks is primarily recommended to managers of various companies and organizations that do not have a system administrator on staff.

Network administration arises when a network administrator has the need and ability to operate a unified view of the network, as a rule, this applies to networks with complex architecture. At the same time, a transition is made from managing the functioning of individual devices to analyzing traffic in individual sections of the network, managing its logical configuration and specific operating parameters, and it is advisable to perform all these operations from one control console.

The problems solved in this area are divided into two groups:

1. Monitoring the operation of network equipment,
2. Management of the functioning of the network as a whole.

The first group deals with monitoring individual network devices (hubs, switches, routers, access servers, etc.), setting up and changing their configuration, and eliminating any failures that occur. These traditional tasks are called reactive management.

The second group is responsible for monitoring network traffic, identifying trends and analyzing events in order to implement prioritization schemes and proactively resolve problems associated with insufficiency bandwidth(proactive, or preventive, administration, proactive management).

To implement proactive administration, it must be complemented by powerful tools for retrospective behavior analysis information system. The main role in this process can be played by dividing the set of possible states of the system into classes and predicting the probabilities of its migration from one class to another.

This also includes the formation of a unified view of the network in order to make changes to its configuration, accounting of network resources, managing user IP addresses, packet filtering in order to ensure information security and a number of other tasks.

The complexity of the processes of administering a distributed computing environment was one of the incentives for the emergence of reduced distributed computing models.

To avoid such troubles, it is necessary to think again about the architecture of the information system and change it if similar precedents are expected in the foreseeable future. The use of server DBMSs is the most suitable solution in this case.

The ultimate goal of network management is to achieve IS performance parameters that meet user needs.

Users evaluate the performance of an IS not by the characteristics of network traffic, the protocols used, the response time of servers to requests of a certain type and the features of the management scripts being executed, but by the behavior of the applications that run daily on their desktop computers.

The general trend in the world of network and system administration is a shift in emphasis from control over individual resources or groups of resources, from managing the performance characteristics of information systems to maximizing the satisfaction of end-user requests. information technology contributed to the emergence of the concept of dynamic administration.

This approach presupposes, first of all, the availability of tools for analyzing user behavior, during which both their preferences and problems that arise in everyday work should be identified. The results obtained at this stage should serve starting point to actively manage the interaction between the main objects of administration - users, applications and the network.

The term “active” implies constant tracking (monitoring) of the nature of work custom applications and prompt intervention in this process when the level of service received by the user does not meet the expected level. To most adequately respond to emerging problems, it is proposed to use analytical decision support tools.

These factors give reason to believe that network and system administration is being replaced by application and service quality management, independent of the computing platforms or networks used.

A separate problem is associated with the creation of complex “end-to-end” management tools that make it possible to combine administration systems installed in partner organizations. The relevance of this task is growing as more and more more widespread extranet networks.

The implementation of Intranet technologies in corporate information systems is not complete without administration. Thus, the widespread practice of employees working on a corporate network from home requires suppliers to create new tools in the field of access control and information security.

Web resource management tools are of independent value, not only in relation to Intranet and Extranet networks, but to a greater extent in connection with the spread of e-commerce.

The evolution of administration concepts affected not only system architecture. New challenges that have arisen in distributed environments have led network management to become a primary concern for information systems administrators for some time.

The situation changed after the number of distributed applications and databases operating on the network exceeded a certain threshold. At the same time, the role of system administration has increased, and the process of integrating system and network administration has become inevitable. It should be noted that managing the operation of a complex heterogeneous network is a more complex task than, for example, monitoring the functioning of network printers.

Integrated network management system (INMS) is a management system that integrates functions related to network analysis, diagnostics, and management.

At the same time, network administration sometimes began to be considered as one of the many components of system administration, and the network as one of the managed resources along with computers, peripheral devices, databases, applications, etc.

The complexity of the administration processes of a distributed computing environment led to the fact that in the fall of 1996, Oracle and Sun Microsystems proposed the creation network computers, and six months later Intel and Microsoft - the concept of network personal computers(Net PC). Despite the significant differences between the two architectures, they marked a partial return to a centralized computing model and to the corresponding organization of all administrative processes.

Thus, the evolution of administration tools and systems is directly related to the development of basic information technologies.

Projects for the development of administrative mechanisms usually include the tasks of establishing strategic management, policy development information support and access to information resources, as well as software and hardware devices, systems and complexes, installation and development of the system, improvement of continuous management.

With the help of local computer networks, enterprises create a single working and information space for your employees. Networks require maintenance at every stage of operation.
