Construction and operation of cloud data centers

1 cloud computing data center
Cloud computing data centers are essentially made up of cloud computing platforms and cloud computing services. Cloud computing services including applications, software, tools and computing resources services to users through a variety of means of communication; the hardware and software platform of cloud computing platform to support these services including the safe and efficient operation of the. Through cloud computing platform of hardware and software of one or more data center integration, virtual computing resources pool to form a hierarchical (Storage Pool), and to provide computing, storage and network communication capacity dynamically and extended, to support cloud computing services.
The cloud computing platform is the backbone of the cloud computing center, located at the heart of cloud computing technology. It takes the data as the center, behind the technology to virtualization, through the establishment of physical and computing resource pool adjustment, integration in the distribution network server cluster (Cluster), storage cluster, combined with the ability of dynamic allocation and smooth expansion of resources, provide safe and reliable application of data service.

2, the implementation process of cloud computing data center
The implementation of cloud computing data center is not a simple hardware and software integration project, need careful evaluation and overall planning before implementation, fully consider the cloud computing data center management mode, and the future mode of operation into the overall planning, so that it can fully play the role of cloud computing platform.
Combined with the investigation and research of cloud computing center user needs and the implementation experience abroad, the implementation of the cloud computing data center infrastructure is divided into the following 5 stages:
1) planning stage: to build a cloud computing center for strategic issues to deal with, top management should pay attention to and support greatly, and clear in each stage to achieve the goal of planning and deployment in business innovation and transformation of the height of IT service.
2) preparation stage: according to industry characteristics, fully understand the user using the cloud computing data center to service and application requirements to obtain, and adequate assessment of the cloud computing platform, select the appropriate technical architecture. At the same time, the operability of system expansion and migration is fully considered, and the continuity of infrastructure platform technology and the continuity of core business are guaranteed.
3) the implementation stage: resource virtualization based cloud computing center, by constructing a virtual platform to support heterogeneous platform, can satisfy the security, reliability, scalability and flexibility and other aspects of the service requirements.
4) the deepening stage: on the basis of realizing the virtualization of the platform architecture, we must also realize the automation of various resource allocation and distribution, and lay the foundation for overall management and self-service.
5) application and management phases: the basic features of cloud computing are openness, cloud computing platform provides standard API implementation, compatible with existing applications. All application porting is a gradual process, and the cloud computing infrastructure needs good core applications, not just new requirements. At the same time, cloud computing platform construction is a closed loop (Closed-loop) process, which needs continuous improvement.
