Build a private cloud platform using Virtualization

cloud computing is leveraging its unparalleled advantages -- pay-per-use (pay-as-you-go) , stepping down from the cloud to the practical application level of enterprise management. Public and Private clouds are often mentioned in basic concepts of cloud computing. In plain terms, public clouds serve everyone, not a company, such as weather forecasts, maps, and emails. Private clouds are the opposite, private clouds only provide services for an enterprise, such as Amazon EC2 (Elastic Computing cloud ). These services allow users to lease virtual computers to develop or run their own applications Programs , paid by the hour.

Cloud computing provides services to users through the software and hardware platform. It can provide virtual infrastructure as needed, efficiently aggregate computing resources into resource pools, and automatically manage and schedule them, and provide external services in the form of service submission. From the operator's point of view, the operator's users provide the software and services required for cloud computing, and the software can also be provided as a service,The cloud computing platform provides three types of services: software implementation as a serviceIAAsPlatform as a servicePAAsSoftware as a serviceSAAS.

In a typical data center, when a server is assigned to a specific application, the server utilization rate is very low, and the total server capacity and cost waste can be as high as 45%, this is why virtualization and cloud computing are generated. Due to the increasing demand for applications, the server capacity is insufficient. virtualization and cloud computing solve this problem by creating resource pools. In terms of technology, cloud computing is an extension of the virtualization concept, and virtualization is the foundation of three categories of cloud computing services. At present, some enterprises have been applied in some data centers.

IDCThe study reports that the virtual private cloud business will grow significantly in the next three years. During a visit to 355 Chinese IT executives and chief information officers, IDC found that nearly half of respondents suggested building private cloud computing platforms based on internal data centers.

Private clouds do not use traditional data centers, but use a combination of highly virtualized computing, storage, and network functions to optimize it performance and utilization, while providing enterprises with services that improve efficiency and flexibility. With the help of the management software framework that implements automated self-service resource configuration and cost allocation functions, private cloud combines Virtual Server Management with sometimes physical server management. Compared with the public cloud, private cloud has obvious advantages in high availability, utilization of existing IT resources, impact on existing IT processes, compatibility with existing IT resources, service quality, and data security, however, IT investment in the early stage, resource utilization efficiency and technical maturity are not as good as public cloud.

Private cloud computing systems are favored by Web 2.0 companies such as Amazon, Google, and Salesforce. Of course, Microsoft is no exception,Earlier in November this year, Microsoft released hyper-V cloud. This cloud computing solution is intended for users who wish to own their own private clouds. This solution provides hardware vendors with a guide, it also provides software suites for deploying Private clouds.
