Data Center Cloud Computing Tour

Today, if you don't know about cloud computing, someone will say you're out, because all of it is talking about cloud computing. But how does cloud computing connect with existing data centers? How do you get the Express on cloud computing from existing data centers? I do not want to explore the concept of cloud computing here, and from the data Center cloud computing trip to analyze the impact of cloud computing.

Before exploring the data center's cloud-computing journey, it is necessary to clarify a myth: Many people think that Amazon, Microsoft and so on have built the cloud platform, directly to the existing data center to move up the cloud is not started? We all know that cloud computing is divided into private cloud and public cloud, Google, Microsoft and so on are built by the public cloud, at the same time, cloud computing can be divided into proprietary cloud and common Cloud, Google, Microsoft and so on build is proprietary cloud. We can easily migrate existing applications to the common public cloud, but the proprietary public cloud cannot afford it. Proprietary cloud needs to be developed specifically to meet applications developed based on specific conditions. Traditional applications to migrate to proprietary cloud, often need to modify the source code. And we have a lot of applications in our existing data centers that don't have the source code, even if you have the source code, you may not be able to find the development team of the year to modify it, which makes the proprietary cloud only suitable for certain application scenarios, for our existing data center dozens of, or even hundreds of applications, often powerless. All, the data center of the cloud trip can not take the exclusive cloud this train. So where should the data center's cloud trip start?

First, the data center's cloud-computing journey starts with building a resource pool. Without the pooling of resources, cloud computing would be impossible to talk about. The so-called pooling of resources, including computing resources, network resources, storage resources of the pool. Only after the pooling of resources can flexible configuration, dynamic adjustment, to be able to have flexibility, improve stability and security. Resource pooling is the first and particularly important step in the entire cloud. When choosing a resource pooling scenario, consider the following five areas:

1. Build on a reliable, proven basis

2. Provide a platform for shared IT services

3. Provide a complete solution for virtualization and cloud computing management

4. Support your entire IT infrastructure

5. Proven in tens of thousands of customer deployments

VMware's Vsphere 4.0, released last year, is the industry's first cloud operating system and the best tool for resource pooling. Vsphere 4.0 has already been able to provide some cloud computing capabilities, and Vsphere 4.1, released in July this year, has been further upgraded from all levels, with the introduction of memory compression technology, storage and network I/O control capabilities to further improve efficiency, control, and selectivity, More to meet the needs of cloud computing platforms. VMware vsphere 4.1 has been fully enhanced from the above five areas to fully meet the needs of the data center to build a public cloud for the private cloud and cloud service providers, and recently VMware, VMworld 2010 in San Francisco, has released and Bluelock, Colt, SingTel, Terremark and Verizon provide VMware Vcloudtm Datacenter Service, an important success story for VMware Cloud Solutions, marking the VMware vsphere and VMware VCLOUDTM director become the most trusted base platform for both private and public clouds. The new features of Vsphere 4.1 are shown in the overview diagram below.
