Private cloud reveals the real private cloud architecture

Everyone has their own ideas, cloud computing in everyone's eyes are different. But there is a certain consensus on many aspects of cloud computing, such as the three-tier architecture (Saas,paas and IaaS). In addition to the three-tier architecture, it is thought that clouds can be divided into three kinds: public, private, and mixed.

The benefits to the cloud: flexibility, scalability, resource sharing, cost reduction, and so on. But many companies feel uneasy about putting information on Third-party servers. These companies are thinking about whether there is a cloud-computing advantage, and they can control the solution of the information themselves.

Private Cloud

The answer is yes, the emergence of the private cloud solves the problem of the enterprise.

What is the difference between a private cloud and a public cloud?

First, we need to understand how the http://www.aliyun.com/zixun/aggregation/13422.html > Cloud Computing technology evolved. I have summed up, mainly by the following points:

Due to the gradual maturation of the key technologies, such as distributed computing, cluster technology and virtualization technology, the server functions are becoming more and more powerful and can simulate multiple virtual machines on a single server.

• For the rational use of resources, the promotion of green environmental protection

• Network bandwidth availability, coupled with browser-based application interfaces and mobile applications, integration of data centers

Dances cost control requirements, as well as service quality and delivery speed.

In this environment, cloud computing is born, public cloud usually refers to third-party providers to provide users with the ability to use the cloud, public cloud is generally available via the Internet, low-cost or even some free.

Private cloud refers to the cloud used by the enterprise itself, and all its services are not for others to use, but for their own internal personnel or branch offices. Because it is built for a single enterprise, the enterprise owns the infrastructure and can control how the application is deployed on this infrastructure, and can effectively control data, security, and quality of service.
