Data center virtualization and cloud computing research and analysis

Virtualization has become a major catalyst for modern data centers, increasing resource utilization, system support options, and resilience, and cloud computing technology is driving it further, making it possible for computing users to provide on-demand configuration and scalability, What is your organization's acceptance of virtualization and cloud computing compared to other technologies in the IT industry?





earlier in 2011, the TechTarget Data Center website searchdatacenter.com released a data center decisions 2011,dcd:2011 Survey, To understand the reader's trends and understand the impact of enterprise data center changes, the survey received more than 1000 professionals from various it fields to respond positively. In this article, we analyze the results of the research on virtualization and cloud technology selection and compare it with the 2010 survey results.




Degree of virtualization in
data centers





Server virtualization has infiltrated the Enterprise data center, and IT professionals are becoming more confident about the technology, dcd:2011 require participants to answer the current status of server virtualization in their organization, and the findings indicate a significant drop in the number of first-time deployments and expansions between 2010 and No. 2011. , as shown in table 1, is understandable because 60% of the objects involved in the survey are currently using server virtualization.

Different uses of
virtualization




The most popular server virtualization use for
is to increase the availability of disaster recovery (DR) and workload, dynamically allocate computing resources and maintain a standardized "Huang image" for rapid deployment of new virtual machines, and server virtualization can also be used as a private cloud platform.




"Some companies think virtualization is green technology, data centers may have 10 years of old systems running, and now they can buy two physical hosts," said Bill fittings,
, head of steel pipe and tubing manufacturer at Illinois State Niles. , perform physical to virtual migrations, migrate old system workloads to virtual machines, and reduce the amount of hardware space. ”





Since 2010-2011, the data center virtualization approach is still very standard (table 1), although virtualization technology is increasing, but the main purpose has not changed significantly.





virtualization arrives at the end of the enterprise





virtualization is now beyond server applications, desktops, notebooks, tablets, smartphones and other endpoint devices are beginning to talk about virtualization, and endpoint virtualization is not a new technology, and many organizations have made basic assessments.





Kleyman said: "The data center will be on the LAN in the form of data flow of the entire desktop to the thin client or dumb terminal, the technology allows the maximum user experience, because only when the user needs the technology flow, reducing the mobile desktop experience required traffic."





DCD Survey results show that the adoption of endpoint virtualization has increased between 2010 and No. 2011 (table 1), and IT organizations have deployed or expanded its use to improve endpoint security and maintenance efficiency.





Virtualization deployment Encounters resistance





not all IT professionals are ready for virtualization, and quite a few are just evaluating virtualization technology and are not planning to deploy in 2011.




The reason why the
organization did not use virtualization was not very different from the same period last year, there are many commonalities, as shown in table 2, where people who manage small environments with only a few servers think that there is no need to add new technologies, on the other hand, the applicability of the application is also a concern because the old or proprietary/ Internally developed applications are probably not suitable for virtualization.








Table 2: Common reasons for not using virtualization


management and budgeting are also important reasons to prevent virtualization from entering the enterprise, often because the organization does not use virtualization because of lack of budget or higher UPS expense approvals, IT professionals should quantify the benefits of virtualization, such as reduced hardware costs, reduced downtime, and so on.





Virtualization Product Selection





There are three major server virtualization vendors to choose from: VMware, Microsoft and Citrix, when asked about the main virtualization products deployed in the enterprise, most of the 2010 and 2011 respondents chose VMware (table 3), DCD : 2011 Of those surveyed have migrated to the latest version of Vsphere 4.0.








Table 3: Most deployed Virtualization products


Microsoft Hyper-V and Citrix xenserver significantly lag behind vsphere, fewer than 3% of respondents deployed other virtualization platforms, such as Oracle VMs, Ubuntu KVM, host partitions, Redhat Enterprise Linux KVM and IBM AIX WPAR (workload partition Management). 123 Next Page
