Application observation: Cloud Computing technology drives telecom business Architecture innovation

In the whole IP network environment, combined with the technical features of cloud computing, this paper analyzes and probes into the innovative application of cloud computing technology in Telecom service network.

With the custom, customization and personalization become the mainstream demand of the users, the traditional telecom service network is becoming more and more independent, and the existing closed-end services model is facing great challenges. In the new competitive environment, telecom business needs to find new architecture and technology direction.

These new architecture and technology direction mainly in the following aspects: first, from centralized deployment to distributed deployment transformation, flat network planning, to achieve a point of access, full network services. Second, the introduction of the new Internet technology to achieve distributed computing and storage, large capacity, flexible scalable, rapid deployment. The third is to achieve innovative business by simply providing the main service and transforming it into the ability of user services, integration of business management, information storage and software services. Four is the integration of telecommunications and Internet services, providing an open development environment, active community services.

With the development of the whole IP and broadband of telecom network, the technology of telecommunication and definable internet have been deepened, especially the cloud computing technology emerging recently, which has aroused the high concern of telecom industry and the development of Internet cloud computing, and the Resources of Telecommunication network (including Access, dispatch, management, storage, Security and services, etc.) in the way of cloud computing has become the new trend of telecom business development, cloud computing brings capex and opex reduction, energy saving and emission reduction, enhance network robustness and flexibility, and so on significant advantages, for operators have a clear appeal.

Typical technical features of cloud computing

The typical technical features of cloud computing, shown in Figure 1, can be categorized into virtualization, distributed, parallel Computing/distributed computing, XaaS, WEB x.0, and other technologies.

Telecom Service network planning based on cloud computing

Referring to cloud computing's distributed layered Service architecture idea, the telecommunications business Network can refer to the plan as shown in Figure 2.

Telecom Service network is divided into three layers, from inside to outside, it is basic service layer, service provision layer and service access dispatch layer respectively. The basic service layer provides a wide range of common and shared basic services capabilities, including storage, database, parallel computing, and the use of virtualization technology for Low-cost, large-scale, high efficiency to provide a variety of infrastructure services, including business engine, business management, business Access Gateway, network management and other platforms, We can adopt unified platform architecture, open telecom capability, and introduce external development force to form benign ecosystem. The service access scheduling layer realizes a variety of applications services access to the Telecommunications cloud computing network, unified scheduling, users can through a variety of wired or wireless access mode, to achieve anytime, anywhere on-demand customized services. In the specific business construction planning, can be staged. The first is the construction of the basic service layer, it mainly realizes the virtualization of the hardware resources, the correlation of the software to the hardware, the maintainability and the rapid deployment ability of the underlying system, the provision of the shared storage resources, the small changes of the existing business software, the direct deployment on the basic service platform to improve the reliability of the business system. Then carries on the construction of the service provision layer and the service access dispatch layer, adopt distributed technology, build business capability engine and dispatch management platform, maximize the ability of virtualization hardware, and make business system flexible and scalable, and provide application development, testing and deployment environment to third parties (including Internet developer community) Enable more users to participate in the deep customization and development of the business.

Technology innovation of Telecom service products based on cloud computing

Corresponding to the cloud based telecommunications business Network planning requirements, in the design of specific products, should also follow the concept of tiered service function, the product according to the IaaS, PAAs and SaaS three layer construction. Cloud based telecommunications business product architecture design schematic diagram as shown in Figure 3.

The IaaS layer mainly uses the virtualization software technology and the chip support ability, the storage, the computational resources (CPU, memory, IO and so on) ability divides according to the configurable smallest granularity, forms the independent virtual machine image, the virtual machine has the unified backup and the migration mechanism. The IAAS layer provides a unified API to realize the unified dispatch and sharing of storage resources and computing resources within the product.

The PAAs layer consolidates existing business capabilities into application servers, business capability access, business engines, business open platforms, and calculates basic service capabilities down to business capability requirements, using the API provided by IAAS, invoking hardware resources, and providing business dispatch center services up, Real-time monitoring of the various resources of the platform and opening these resources to SaaS users through APIs. In the three-tier architecture, PAAs is the direct embodiment of the core competencies of the business.

The SaaS layer includes basic applications and multi-tenant applications, through the API interface provided by the PAAs platform, which enables the invocation, encapsulation and user services of business capabilities. The basic applications include the traditional telecommunications business capabilities, such as unified portals, multimedia, voice, data, and many other applications, including personal applications, enterprise applications, community and mobile stores. Multi-tenant business is applied more on the Internet, the application instances between different tenants can be shared and load balanced, but the application of SaaS technology can optimize the development mode of the telecom business.

Cloud Computing Application Summary

Cloud computing technology is still evolving, many concepts have not been recognized by the industry, standardization work is relatively lagging behind the development of applications, through the introduction of these new technologies, in the telecommunications business application and transformation, can achieve resource sharing, cost reduction, architecture optimization and business innovation, for the telecommunications business has brought new opportunities for development. With the deepening of the internet and telecom convergence, we believe that the future of cloud computing technology will open up a new blue sky for the telecom business.
