With the increasing of enterprise informatization application system, the space, electricity distribution system and air conditioning refrigeration of data centers tend to be saturated. Simultaneously, the utilization rate of the servers is generally low. In order to solve the contradiction between the development of data center and the rapid growth of information resources, the concept of cloud computing and the virtualization technology provide the means to optimize the traditional data center. Therefore, cloud computing data center appears. Then in this article, there will be an overview of cloud computing data center.
Before coming into today’s topic, it will be better to have a knowledge of some information about cloud computing and traditional data center, by which you will find what relations exit between cloud computing and data center. Simultaneously, it also will be helpful for you to know cloud computing data center better in the following introduction to it.
What Is Cloud Computing?
Cloud computing is divided into public cloud, private cloud and hybrid cloud. Cloud computing refers to the delivery and utilization modes of information technology infrastructures in a narrow meaning; while it means that the delivery and use patterns of services in a broad meaning. Cloud computing has 3 service modes: IaaS, PaaS, and SaaS.
What Is the Traditional Data Center?
The traditional data center is the generic term of all IT devices and information systems in the network center. It provides information services for the enterprises or the public through the network. The information system contributes to the standardization of business process and the improvement of operation efficiency for the enterprises. The data center provides a stable and reliable infrastructure and running conditions for the information system, also ensures the convenient maintenance and management of the information system.
An Overview of Cloud Computing Data Center
1. What Is the Cloud Computing Data Center?
80% of cloud computing data centers in enterprises are generally deployed with private cloud. Cloud computing data center refers to the data center optimized by the means of application virtualization.
2. The Structure of Cloud Computing Data Center
The structure of cloud computing is divided into two parts: service and management. In the aspect of service, it mainly focuses on providing various services based on cloud, which includes 3 levels: Infrastructure as a Service(IaaS), Platform as a Service(PaaS), and Software as a Service(SaaS).
3. The Constructions of Cloud Computing Data Center
The core technology of cloud computing data center is the virtualization technology. The main objects of virtualization are servers, storage, network and desktop. Thus, a brand new mode to deploy and manage data center is formed. In fact, 3-clouds resources and services need to be constructed.
- The Construction of IaaS
The infrastructure layer, based on the IT resources, includes the collection of hardware resources and related management functions after virtualization. The delivery of infrastructure services to users is the most fundamental infrastructure resources, providing users with virtualized computing resources, storage resources and network resources.
- The Construction of PaaS
Platform layer, based on platform service and middleware, provides middleware and basic services related to application development, deployment and operation, which can better meet the requirements of cloud applications in scalability, availability, and security.
- The Construction of SaaS
Application layer is a collection of application software on the cloud, which are built on the environments provided by the resource and platform layer from infrastructure layer and delivered to the users through the network.
4. The Advantages and Influences of Cloud Computing Data Center
- Improving the Utilization Rate of Resources
Compared with the traditional data center, the cloud computing platform provides flexible services that can dynamically allocate and release resources in a large pool of resources according to the demands of users, without the need to reserve peak resources for each user, so that the utilization rate of resources can be greatly improved. In addition, there are more users in the cloud data center, then the cost to improve energy efficiency is relatively lower. After that, the cost can be apportioned to more servers.
- Flexible to Extend Resources and to Improve the Reliability
The “cloud” resources applied by users can be adjusted and dynamically expanded according to the requirements of their applications, able to effectively meet the needs of large-scale growth of applications and users.
- The Data Centers of Small Enterprises Are Gradually Weaken
After entering into the era of cloud computing, IT has transformed from the self-sufficient workshop mode at early period to the industrialized operation mode with a scale effect. Some small-scale data centers personally owned by enterprises will be eliminated, and the data centers with large scale and reasonable configuration resources will take place of them.
- More Specific in Specialized Responsibility Division
Cloud computing data center is larger-scale, and more specialized than data centers with small/medium scale, higher management level. In addition, it can also provide lower cost needed by unit calculation. Therefore, the costs taken in labour can be cut down to a large extent, and the specialized responsibility division is more specific.
The way to upgrade traditional data centers is found by the analyses on cloud computing and virtualization tech. This makes it possible to implement application, develop the new-generation data center to save resources and reduce power dissipation.
