Shulou(Shulou.com)06/02 Report--

In large group enterprises, the companies under the group usually build data centers and a series of IT operation and maintenance systems independently.

With the development of IT technology, the requirements of operation and maintenance are becoming more and more diverse, and the architecture of operation and maintenance system is becoming more and more complex. as a result, more and more large group enterprises begin to change their ideas and consider building a unified integrated operation and maintenance system.

This paper will introduce how large group enterprises introduce Internet concept and technology to build an integrated operation and maintenance system, so as to lay the foundation for the realization of information and digital transformation.

Current situation of IT Operation and maintenance in large Group Enterprises

1. Characteristics of organizational structure

Generally speaking, large group enterprises will set up multiple companies or business departments under their business sectors, regions or mergers and acquisitions, and multiple subsidiaries or sub-divisions will be set up under each company or business department. each company or business department operates a certain business relatively independently, but it also has a close relationship with each other, as shown in the following figure:

As each unit of each level of organization undertakes independent business responsibilities, and each unit has the authority to build its own IT system, the units under the operation group may have built one or more IT data centers after years of operation, running a large number of IT infrastructure and business systems.

2. Current situation of IT operation and maintenance system

In order to ensure the stable, efficient and safe operation of the IT infrastructure and business systems of all levels of units, the group's units at all levels generally plan and build a complete set of IT operation and maintenance systems independently. For example, the security and operation support class system shown in the following figure:

3. Pain point analysis of IT operation and maintenance.

From the point of view of integrated management, collaborative integration and digital transformation, this "chimney" and "decentralized" construction mode of IT operation and maintenance system at all levels mainly has the following problems:

Diverse systems and complex architecture

Due to the lack of unified planning, units at all levels have independently carried out the planning and construction of IT operation and maintenance system for many years, and have accumulated a large number of operation and maintenance products of different manufacturers and different architectures or self-built operation and maintenance systems of various units. Each individual operation and maintenance system is responsible for solving the operation and maintenance needs of a certain aspect of the unit.

For example, the server monitoring system in IT monitoring system may include products from many manufacturers, such as Microsoft, Hewlett-Packard, IBM, China soft, Beita, Zabbix and so on.

It is difficult to coordinate horizontally between systems.

Due to the different vendors and architectures of all kinds of IT operation and maintenance systems, there is no interface for collaborative interaction. At the same time, due to the different data specifications and formats of each system, the data can not be effectively unified.

For example, the configuration data in the IT monitoring system differs greatly from the configuration data in the ITSM and cannot be shared; the configuration data automatically collected by the IT monitoring system cannot be automatically matched and updated to the IT asset system; and the security indicators provided by different vendors of security equipment and security systems of different units vary greatly, resulting in a unified security index display and horizontal comparison at the company level.

The data of operation and maintenance is of poor quality and can not play its value.

As there is no unified standard specification for the data of each unit's IT operation and maintenance system, the accuracy and consistency of each data are poor, the data quality problems are prominent, and it is difficult to implement a unified quality improvement scheme.

Therefore, it is impossible to analyze, mine and apply based on the existing operation and maintenance data of various units, and the data is of little value and can not achieve unified operation.

The cost of system construction and operation and maintenance continues to increase.

Due to the independent planning, construction, deployment and operation and maintenance of each unit's IT operation and maintenance system, with the gradual increase of the complexity of IT operation and maintenance requirements, more and more data, automatic and intelligent operation and maintenance requirements are constantly put forward, and most of the operation and maintenance requirements of all units are similar.

If each unit continues to plan and build the operation and maintenance system independently, it will lead to a continuous increase in the overall system construction and operation and maintenance costs at the whole group level, and there will be a lot of repeated investment.

The application of new technology is uneven

The traditional IT operation and maintenance system technology is backward, and it is difficult to meet the current requirements of rapid development and fine management and control of enterprise applications. With the continuous emergence and maturity of new Internet technology, each unit introduces new technology on its own, which is bound to result in a large number of repeated research investment, and the degree of technology application is uneven.

New ideas for IT Operation and maintenance of large groups

1. New ideas of Enterprise IT Operation and maintenance

Based on the analysis of the current situation of IT operation and maintenance of large groups, in order to meet the increasingly complex needs of IT operation and maintenance and realize the digital transformation of operation and maintenance, large group enterprises need to change the construction idea of operation and maintenance system, from the original "chimney" and "decentralized" construction mode to "integrated" and "centralized" construction mode, and introduce the emerging technologies and tools of the Internet to create an one-stop IT operation and maintenance business "ERP".

two。 Design idea of Integrated IT Operation and maintenance system

In order to meet the complex operation and maintenance requirements and have good expansibility, the overall design idea of the integrated IT operation and maintenance system is as follows:

Platform + application mode:

The basic platform of integrated operation and maintenance system is established, and the scene output mode is used to decouple the application function.

Provide convenient and rapid service combination function, each molecular company can realize personalized operation and maintenance application according to the actual management needs, and fully support the full lifecycle operation and maintenance management from the perspective of operation and maintenance scene.

Full coverage of IT operation and maintenance functions:

Coverage of existing IT asset configuration management, IT infrastructure monitoring, IT application monitoring, IT service management, IT security monitoring, IT calls, IT facility inspection and other functions

At the same time, it is necessary to reserve the expansion capability for the future automatic and intelligent operation and maintenance scene, and construct the operation and maintenance management with supervision, management and control in one.

Unified portal, centralized deployment:

Establish the unified operation and maintenance portal of the whole group, realize the unified entrance of operation and maintenance of the whole group, and display the panorama of service and support.

Using the first-level deployment model, the platform and applications are deployed at the group headquarters level, and molecular companies deploy local agents to integrate and manage IT infrastructure and systems at all levels of units.

Advanced technology architecture:

Abandon the traditional monolithic design pattern and adopt the industry's advanced PaaS+ micro-service design pattern.

Using distributed and highly available technology to achieve high availability and high performance of the platform

It adopts open and standardized platform interface design to support scene-based extended development.

IT operation and maintenance blueprint planning for large-scale collectivized enterprises

1. Brief introduction of platform Architecture

Through the research and comparison of a variety of technologies and platforms of Internet companies in the industry, the most advanced and complete operation and maintenance system architecture in China is Tencent's integrated R & D and transportation PaaS platform.

As shown in the figure above, the platform is a multi-level and scalable platform for integrated research and transportation capabilities that can be applied to a variety of IT data centers:

IaaS layer: can support enterprise traditional data center, virtualization, private cloud, public cloud, hybrid cloud and other IT infrastructure.

PaaS layer: it can provide configuration management, container service, management and control services, big data computing, big data storage, machine learning algorithm and other advanced Internet technologies, as well as configuration platforms, job platforms, management and control platforms, container platforms, data platforms, development frameworks and other modular and reusable capabilities developed based on these technologies.

Basic SaaS layer: can provide applications and tools used in a variety of IT scenarios, such as continuous integration, release of changes, fault handling, experience optimization, auxiliary operations, operational security, etc., to meet the needs of enterprise IT development and operation integration in the whole lifecycle of "continuous integration-continuous deployment-continuous operation" (CI-CD-CO).

Scenario SaaS layer: by providing the underlying development, operation and maintenance capabilities and tools, enterprises can support enterprises to build a variety of complex, personalized application systems that meet specific scenarios according to their own needs.

two。 Functional Architecture Planning of Integrated IT Operation and maintenance system

According to the IT OPS requirements of large collectivized enterprises, combined with advanced Internet technology ideas, the integrated IT OPS system architecture shown in the following figure can be designed based on the platform:

The group headquarters centrally deploys the integrated IT operation and maintenance system, which provides access to the users of the whole group headquarters and units at all levels.

Each sub-company deploys a local proxy server to supervise, manage and control the infrastructure and application systems of the local IT data center, and integrate with the integrated IT operation and maintenance system of the group headquarters through the data bus:

Collection Agent:

Responsible for collecting the configuration information, correlation, performance information and running status of the local infrastructure and application systems of each unit, and reporting the collected information to the collection center of the group headquarters through the data bus, and then provide it to each operation and maintenance scene application.

Management and control agent:

Responsible for the operation and control of the local infrastructure and application systems of each unit, including document issuance, command execution, etc., cooperate with the management and control center of the group headquarters, and accept the operation instructions from the operation and maintenance scenarios of the group headquarters. such as service start and stop, file replacement, etc.

Data Agent:

It is responsible for receiving the operation and maintenance data of each defined format sent by the local infrastructure or application system of each unit, and reporting the operation and maintenance data to the data center of the group headquarters through the data bus, which is provided to the application analysis or display of each operation and maintenance scene.

Service Agent:

It is responsible for registering, encapsulating and converting the API interface provided by the integrated IT operation and maintenance system of the group headquarters to the local application system call of each unit, or registering, encapsulating and converting the API interface provided by the local application system of each unit to the integrated IT operation and maintenance system call of the group headquarters.

A case study on the Construction of IT Operation and maintenance system in a large Group Enterprise

Recently, the author has participated in the planning and construction of the integrated IT operation and maintenance system of a large domestic group enterprise. The enterprise group has jurisdiction over more than 10 second-level units and more than 200 third-level units, and each unit has built a large number of IT operation and maintenance systems before the project.

By introducing the above platforms and based on the "platform + application" model, the project newly constructed a group-wide integrated IT operation and maintenance system, providing an one-stop IT operation and maintenance comprehensive management system for thousands of IT operation and maintenance personnel from all units of the group, and supporting each unit to independently expand personalized operation and maintenance scenarios based on the system.

The main function of the integrated IT operation and maintenance system is centrally deployed in the group headquarters, and the platform local agents are deployed in the secondary and tertiary units to gather the massive and detailed operation and maintenance data of each unit to the headquarters in real time for unified storage and application.

The system takes CMDB as the core, constructs the scene functions of IT monitoring, operation and maintenance process management, automatic operation and maintenance, IT call, safety monitoring and early warning, integrates supervision, prevention, management and control, and technically realizes the comprehensive integration of security and operation and maintenance business.

At the same time, through the launch of the system, the enterprise has realized the transformation from traditional manual operation and maintenance, script operation and maintenance to automatic and intelligent operation and maintenance, promoted the standardization, standardization and systematization of operation and maintenance work, and reduced the cost of operation and maintenance. improve the value of the operation and maintenance department.
