云环境下基础设施层的研究与设计

Research and Design of Infrastructure in Cloud Environment

云计算是当前计算机技术的一次革命.云计算对用户表现为各种服务,包括基础设施即服务、平台即服务、软件即服务.其中基础设施层为用户提供硬件资源,是其他各层提供所有服务的基础.对基础设施层的物理构成及其功能进行研究,设计了一个小型的云计算环境下的基础设施层,主要包括总体设计、虚拟化方案以及服务流程,该设计模型能够完成所有基础设施层应具备的基本功能,适应各类型基础设施服务提供企业融入云环境并为用户提供服务.

Cloud computing is a revolution in computer technology. Cloud computing takes a variety of services as embodiment to users, including infrastructure as a service, platform as a service, software as a service. The infrastructure layer to provide users with the hardware resources is the foundation of other layers to provide all services. The study on the physical structure and its function on the infrastructure layer designs a small infrastructure layer in cloud computing environment, which includes system design, virtualization solutions and service process. And the design model possesses all the basic functions that the infrastructure layer should have and adapts to all types of infrastructure services to provide enterprises with cloud environment and to provide services for users.
