China Unicom OSS Two-tier architecture clear introduction of cloud computing implementation of centralized construction

Cloud computing is a new method of computing, through virtualization and other technologies in accordance with the "Plug and Play" approach, self-service management capabilities to form an efficient resource pool, on-demand service form to provide computing power. In recent years, with the development of cloud computing technology, the domestic operators in many professional fields from different degrees, different directions of the cloud computing environment to build the attempt and implementation work. In this upsurge, the OSS system, one of the most important supporting systems of the operators, is trying and pushing forward in order to follow the development step.

At present, there are many system vendors in China Unicom OSS system, management and maintenance is complex, OSS system adopts "silo type" construction, lacks unified planning, low resource reuse rate, independent construction of each network management system, design difference is big, idle resources cannot share reuse. Cloud computing IaaS level of technical advantages: resource sharing, on demand, rapid deployment and so on, very good solution to the current stage of business platform development and operation of the main problems, cloud computing for the major operators is not a new technology, but a new business development model, a new system construction methods, A new idea of maintenance management.

Current situation of OSS systems

China Unicom has now built a headquarters and provincial two-level operational support system system for Headquarters, provincial and municipal branches of three users. Headquarters users through the use of the headquarters system to complete the maintenance of the national network management, each provincial branch company completes the maintenance management of the province network through the provincial operation and support system of the province construction, and the users of the city use the provincial system to complete the maintenance and management of the local network, and the headquarters operation and support system and the provincial operation support system have vertical interface. , can carry on the business, the information exchange.

At present, the integrated electronic operation and maintenance system is this structure mode, this kind of system structure construction way, in the current system operation increasingly show some problems, such as:

1. The failure of the interface or the headquarters or the provincial-level system will result in the lack of information between headquarters and the provincial system.

2. Provincial-level electronic operation and maintenance system to complete the provincial network management, for provincial-municipal circulation of work orders, headquarters in the headquarters of the electronic operation and maintenance system can not be viewed or supervised, can only be viewed locally, so that the headquarters of the country's operation and maintain work is not easy to manage, operational dimension efficiency is not high;

3. Systems are being built both at Headquarters and at the provincial level, not only for high cost, construction cycle is long, and when the number of provincial-level system at the same time online increase in data concurrency increase, the system load surges, the ability to slow and need to expand, the province is unable to change, can only wait for the headquarters of the construction projects can be carried out, which will cause the system has been running high , it brings great hidden trouble to the system security, but the application personnel is the feeling system reaction is too slow, the work efficiency drops.

In this case, we need to introduce cloud computing technology to change the current system situation.

System Transformation After cloud introduction

After the introduction of cloud computing technology, the operation of the support system from the original independent construction, decentralized maintenance mode, the development of operational support system of intensive operations management, system construction from the original headquarters and provincial level two to transform into a unified headquarters level, so as to reduce the cost of construction, achieve efficiency improvement, reduce management and construction of all aspects of the cost, Improve operation efficiency, realize management promotion, data centralization through system, realize unified management, and improve management ability.

After the introduction of cloud computing, the existing problems of electronic operation and maintenance system can be solved:

1. There will be no further loss of interactive data due to two sets of systems;

2. The system administrator at Headquarters can view the work flow in each province through the setting of the authority, the headquarters of each province's operation and maintenance workflow work is at hand, the national operation and maintenance management more convenient and concise, improve the management level;

3. System construction by Headquarters unified planning, construction, maintenance, so as to enhance the utilization of resources, the system can make accurate judgment on the operation of the system, in a timely manner to improve the system's security.

Using cloud framework for operational support

Through cloud computing, we can realize the unified platform of operation and maintenance support system, improve the speciality, unify the resources, use the virtualization technology to realize the sharing of the resources "space and time", improve the utilization of resources, and improve the management level according to the business requirement. In addition, because the resources and the platform to unify, brings the management and the operation dimension support aspect high efficiency also is self-evident.

However, the upgrading of operational support systems should follow the principles of unified standards, interconnection, protection of investment, and full benefit of the old. Should consider the present situation, through the introduction cloud storage Management system, the virtualization transformation as well as the cloud computing management platform realizes the unified system resources management, realizes gradually from the shaft to the unified support transition, from the original independent construction, the decentralized maintenance pattern, gradually develops into the intensive operation management.

After the unified deployment of the operation and maintenance support system in the cloud computing unified resource pool, its operation model can evolve from the traditional "vertical" maintenance mode to "transverse" mode, and the system is planned and allocated on demand independently by a unit or department, and the maintenance work can be further separated and managed and maintained by an independent department. It can be seen that after the "cloud" transformation, the relevant operation and maintenance system and organizational structure need to make adjustments.

However, because of the complexity of OSS systems, we should first choose a representative, generic system, such as an electronic operational dimension system and a resource management system, in a cloud platform test, which has data interaction in the workflow. Then, according to the test results, the other systems in OSS system are reformed to realize the steady transformation of OSS platform cloud Platform.
