Three main approaches to cloud computing "landing"

The fourth annual benchmark survey, conducted by platform company in 2011 at the International Super Computer Conference (ISC2011), also shows that as more and more enterprises use private cloud to significantly improve the resource utilization of the data center, the degree of understanding and recognition of the technology by business decision-makers has improved markedly. The number of companies planning to deploy a private cloud has grown from the previous 28% to the current 33%.

The root cause of
's need for cloud computing is that traditional it methods don't work. In the face of fierce competition in the market, the existing application and Server island model can not meet the ever-changing needs of enterprises. Today, it is expensive, unresponsive, and well-funded, but ultimately the resources available are underutilized. Most servers use only 20% or less. The lack of flexibility, time and cost of buying expensive systems to meet each business requirement is equivalent to installing a small generator in each office to ensure power. IT departments must provide a competitive service model that delivers infrastructure and computing resources through Plug and Play, Pay-per-use services. Cloud computing is leading us towards that goal.


　　


So, despite the current hype on cloud computing, cloud computing is definitely not a flash in the pan, it's the next logical step in the development of the data center from mainframe to client/server to the current cloud computing process. Of course, before implementing the cloud strategy, companies must identify the authenticity and evaluate the value of cloud computing correctly.


　　

The best way for
to assess the value of cloud computing is to assess the economic drivers that make large and medium-sized enterprises adopt private clouds. Cloud computing enables IT departments to maximize the efficiency of computing, network, and storage resources, while reducing costs, speeding the delivery of IT services, and leveraging the power of resource sharing. This helps businesses deliver IT services faster-by eliminating or simplifying enterprise-entrenched islands IT systems migrate to an infrastructure that can respond to new business requirements in real time, reduce IT costs-more efficient use of IT resources, meaning that fewer servers are needed, reducing the footprint of the data center, Power and cooling requirements, in addition, there is no longer a need for IT organizations to provide a resource-configured island of excess infrastructure for each application to meet expected peak demand and reduce capital expenditure.


　　


Three ways to cloud computing


　　


all roads lead to Rome! Although there are many ways to move from an existing client/server infrastructure to cloud computing, for enterprise users, platform believes there are three ways to be the most important and proven to be the most effective. These three ways are:


　　


from virtual machines to the cloud-for users who already have applications deployed on virtual machines, you can combine virtual servers to form manageable virtual machine clusters. As the number of virtual machine clusters increases, so does the need for resource sharing, and companies start deploying virtualized management platforms to automate the provisioning of virtual machines and computing resources across virtual machine clusters, creating a private cloud that is run by the IT department within the enterprise.


　　


from grid to cloud--some businesses are already running grids. This distributed system is managed by IT personnel and is often shared by compute-intensive or data-intensive applications. Virtual machine technology is not used in grids because each application can easily consume all the resources on a single server. In addition, multiple servers are often used together to run parallel applications. By deploying cloud management software, the grid can expand its scope to support more types of applications. Virtualization Technology and resource configuration tools enable the enterprise grid to become a private cloud.


　　


from desktop to cloud-applications can migrate from dedicated servers to shared infrastructures and access from client devices.


　　


Enterprises can choose any of the above approaches, and even choose several ways to implement cloud computing for different applications or different business units. To ensure success, the adoption of cloud computing should follow an orderly, step-by-step approach, rather than a hope for overnight. The progress made depends on the scalability and cost-effectiveness requirements of a particular application, or on features such as automation of business processes.
