Data Center trend analysis: cloud computing and green

Core tip: Throughout history, in the past, regardless of the application level or size of the data center, server leasing is only stuck in the past limited http://www.aliyun.com/zixun/aggregation/13748.html "> Infrastructure, Using traditional simplified instruction set computer and traditional mainframe, each infrastructure is isolated from each other, without forming a unified organic whole. In the past data centres, resources have not been used efficiently and fully. Moreover, the traditional data center resource configuration and deployment are mostly manual, without corresponding platform support, so that a large amount of human resources in the heavy duplication of work, lack of self-service and automatic deployment capacity, both time-consuming and cost, but also seriously affect the efficiency.

In the era of cloud computing, the data center needs to be advanced to the centralized large-scale sharing platform, and the data center can realize the real-time dynamic expansion to realize self-service and automatic deployment service.

Today's increasingly popular new IT models, such as cloud computing, virtualization and cloud storage, once again show that the isolated, lack of organic integration of data center resources in the past has not been effectively utilized, and can not meet the current diverse, efficient and massive business application requirements.

The data center gradually transitions to the cloud, which includes both a private cloud and a public cloud. Private cloud is to transform and restructure the existing data center of the enterprise, automate the dispatch and distribution of resources through cloud computing, and implement a data center architecture of automatic deployment, automatic management and automatic operation. The public cloud is a service provider that builds IT infrastructure and provides business services to external users who can access these services over the network without having cloud computing resources. Compared to private cloud, all the applications, services, and data of the public cloud are stored in the cloud, and user data is not stored in the enterprise's internal data center.

The so-called "plum although the snow three points white, snow is lost a section of incense", in contrast, the private cloud than the public cloud in the data security has better performance, but the public cloud will be more than the private cloud has a more "strong cloud structure." Therefore, from the point of view of the evolution of data center, the discussion of what "cloud" has no real meaning, we should pay more attention to the role of data center in the future development and the historic change.

In the long run, the data center needs to gradually transition to the "cloud infrastructure for mainstream enterprise adoption, proprietary architecture for critical applications" phase, and ultimately achieve a "strong cloud architecture for all the load", regardless of mainframe or x86 are integrated into the cloud, the hardware and software resources to achieve a high degree of integration.
