Server virtualization is still a hot trend today, and it is getting hotter. Gartner believes that the number of virtual machines deployed on servers in 2011 will be more than the total number of deployments in the nine years from 2001 to 2009, and will be popular among medium-sized enterprises of 100 to 1,000 people, even surpassing the world's top 500 companies. Such a big business.
popular at the same time, users of server virtualization still has a few misconceptions. Whether these misunderstandings involve issues such as market, direction of development, and virtualization strategy, these misconceptions can lead to poor investment and wrong decisions. So we have to correct these problems and clear out the big mistakes in server virtualization.
Myth # 1: virtualization wave of heat as before
the end of 2009, about 10.8 million servers virtualized, a year later that number It will rise to 20 million, and by 2011 it will be nearly 35 million. From the overall penetration of virtualization in the server market, only 19% of workloads were virtualized at the end of 2009, and by 2014 it is expected to be close to 70%. Therefore, we believe that in the overall architecture of server hardware, virtualization management software and data center, the impact of server virtualization in the market is still very large, not to be underestimated.
Myth 2: server virtualization primarily for large enterprises
early adoption of server virtualization users are mainly large enterprises. But according to recent surveys, about 30% of medium-sized companies have started the virtualization process before 2009. By last year, this number had almost doubled. Large enterprises need to deploy virtual machines when upgrading or deploying new servers. Midsize companies tend to virtualize many servers at once with the help of outsiders. And many small businesses have joined the ranks of server virtualization within a year.
Myth # 3: Using server virtualization can save money
no doubt, server virtualization through consolidation and standardization, can reduce the potential financial, energy, the data center The cost of space and other space. Although low-end virtual machine technology may be cheap, virtualization increases the complexity of IT operations and requires new management tools. These new issues will bring new spending. In addition, server virtualization requires centralized storage, and migrating legacy systems to NAS or SAN architectures is quite expensive. Therefore, only server virtualization can achieve better standardization and automation, and it is possible to increase or even reduce operating costs.
Mission 4: Choosing virtualization is just a new product
When many companies start to virtualize projects, they don’t realize that they can reduce costs. What are the consequences of server virtualization. There is nothing wrong with saving money, but virtualization will lead to a shift in the overall IT strategy of the enterprise, moving towards a flexible and efficient, cloud computing direction. In addition, technologies deployed on virtual servers will impact existing infrastructure management tools and day-to-day operational processes. To be on the safe side, companies should prepare an alternative to this before starting virtualization.
Myth 5: virtualization and IT
only virtualization related to the sweeping trend affecting IT departments, they need to relax the existing rules, so that different Workloads enable the sharing of computing resources. More importantly, it is necessary to respond quickly to the needs of IT customers. Virtualization makes IT hardware resources no longer constrained by business application deployment. When IT customers need computing or storage resources, virtual servers can be delivered in 2 or even 20 minutes instead of the past 2 months. This speed has fundamentally changed the service delivery business. Gartner customers report that many companies that use virtualization tend to double their business. This confirms that faster delivery speeds lead to greater business volume.
Myth 6: VMware lack of a dominant competitor
in server virtualization VMware although it still occupies 85% of the virtual machine market share, but this The situation is quietly changing. In 2010, there were quite a few virtual machines deployed on Microsoft Hyper-V, especially small businesses that were new to virtualization. In addition, 5% of the virtual machines chose Citrix's XenServer. The server virtualization market is growing and competition is growing. In particular, the virtualization market for mid-sized companies has seen significant growth over the past two years. In the low-end market, the price war has been fierce, and the final price cuts and discounts are likely to occur.
