构建高效的云平台应对国网业务新需求的挑战

云计算是一种计算模式,在这种模式下,应用、数据和IT资源以服务的方式通过网络提供给用户使用,其资源（包括计算能力、存储能力、交付能力）都是动态的、可伸缩的、被虚拟化的,而且以服务的方式提供.SG186工程建设使国家电网公司的软硬件基础架构得到质的飞跃,但随着公司信息化建设的不断深入进行,新业务需求的不断涌现,信息设备数量高速增长,不可避免地带来了诸多问题,包括：IT烟囱式建设不利用资源的有效利用,IT系统的运维与监控复杂度大幅增加,数据中心的建设成本不断攀升,不能及时响应新业务的需求等.通过引入云计算、虚拟化等先进信息技术将有助于解决当前和今后IT建设面临的困难,通过应用这种新型的资源组织、分配和使用模式,有利于合理分配计算资源并提高其利用率,快速响应业务需求,促进节能减排,实现绿色计算等.

Build Efficient Cloud Platform to Meet the Challenges of the New Demand from its Chinese Business

Cloud computing is a computing model which provides application, data, and IT resources in the form of services, through network. Its resources including computing, storage and delivery capacity are dynamic, scalable, virtualization, and provide in the form ofservices. SG186 improves software and hardware infrastructure of state grid corporation effectively. But with the deepening of the information system construction, coming of new business requirements and rapid growth of equipment, it brings many prob- lemssuch as low usage efficiency based on chimney construction, increasing complexity of IT systems operations and monitoring, risingcost of data center, response time of new business, etc. With the introduction of advanced information technology such as cloud computing, virtualization, we will resolve more IT difficulties in the present and future. It can also be advantageous to improve the utilization ratio and business needs through the application of this new type of resource organization, distribution and usage pat- terns.Finally it will promote energy conservation and emissions reduction, lift up green computing development.
