Deployment of Information-based private cloud 1

First, popularize knowledge. Cloud computing can be divided into three types from the perspective of service methods: Public clouds that provide open computing and storage services to the public ", such as Baidu search and various email services; deployed in the firewall to provide a "private cloud" for a specific organization "; and the "hybrid cloud" that combines the above two service methods ". From a technical perspective, cloud computing can be divided into four layers: Haas (hardware as a service), IAAs (Infrastructure as a service), Paas (platform as a service), and SaaS (software as a service ).

IAAs (Infrastructure-as-a-service): Infrastructure as a service. Consumers passInternetServices can be obtained from the complete computer infrastructure. For example, hardware server rent.

PAAs (Platform-as-a-service): Platform is a service.PAAsIn fact, it refers to using the software development platform as a serviceSAAS. Therefore,PAAsYesSAASA type of application. However,PAAsCan accelerate the emergenceSAASDevelopment, especially AccelerationSAASApplication Development speed. For example, personalized software development.

SAAS (Software-as-a-service): Software is a service. It isInternetThe software model is provided. You do not need to buy software, but rentWebTo manage business activities. For example, the sunshine cloud server. Baidu

Currently, in The IAAs field of the cloud computing market, vendors such as EMC, Amazon EC2, inspur information, Lenovo, and founder technology are representatives. Among the vendors that provide PAAs services, typical examples include IBM's "Blue cloud", Microsoft's windowsazure, Google's apps, and domestic Dr. Peng and chinanetcenter technologies. The top-level SaaS Field, neusoft group, yonyou, Kingdee, Kingsoft, shenzhoutaiyue, and Beijing xunbird are all leaders in the corresponding vertical fields.

We were lucky to have participated in the Privatization Project of informatization construction, from project requirements, bidding to investigation. Every process involved, and finally decided to select a new company to participate in Integrator deployment. The launch of a batch of new systems in information construction requires hardware resources, while private cloud is just ahead of the times, so this project is worth it. Let's talk about the limitations of independent servers. The most commonly used data centers are IBM x365.. sequences. To better integrate resources and achieve high availability (ha ). Private cloud is a good choice. It can improve the availability and reliability of business systems, make it easier for users to use, speed up the release of business systems, reduce hardware investment and personnel maintenance costs, and save energy. Specifically, through the comprehensive deployment of VMware virtualization solutions, we have effectively created a private cloud data center on campus and completely solved the problems of integration of teaching storage devices, Disaster Tolerance and backup, data security and stability assurance, etc, meanwhile, physical hardware resources are combined to form a shared virtual resource pool, implementing server virtualization and cloud desktop construction, greatly reducing it costs and optimizing IT resources, it accelerates the process of teaching informatization in various teaching units and actively promotes the construction of teaching, student, personnel, campus card and many other application systems and the construction of resource sharing platforms.
