The use of cloud server features, companies can put a very low cost access to high computing power, that is, companies no longer need to invest in expensive hardware, the burden of frequent maintenance and upgrade costs. The beauty of cloud computing is one that is based on the calculation of the need to allocate users can maximize the performance of large-scale computer clusters, but also to make better resource allocation. If you only use 5% of the resources, we only need to pay that part of what you need. 
In the absence of a cloud server, if the developer intends to develop applications, you first need to consider the purchase and maintenance of the server problem, be prepared to pay, detailed plan, connection and maintenance. Small developers usually buy or lease a server, and then will host its go out, then, you will be responsible for hosting the other factors of each server room, electricity, and internet access. For businesses, we need to establish myself this whole system, which is obviously a great investment.
Meanwhile, as companies share infrastructure services through the cloud server, cloud computing can allow people to get a lot of very cheap computing resources. And compared to spend money to buy their own computers and networks, users can lease almost all the services required, which also led to the outbreak of enterprise innovation. Before companies need to build their own data center, you can use these technologies to the fast-growing low-cost, and get more data, that is, from Groupon and LivingSocial Amazon's AWS services to growth services Rackspace now buy giant, if Groupon build their own server for data processing, estimated in this period will be a drag on their own servers caused by "dead."
Similar live such a huge consumption of today's big data, it is difficult for enterprises' responsibility. Especially in the last byte of data centers are present in the form of business in addition to software and hardware investment, but also inevitably land and maintenance costs (such as human resources, backup power, air-conditioned environment) but also on the increase investment, this not only occupy a lot of costs, with a variety of resources and regulation is also a lack of flexibility.
Until the technology of cloud computing, such a predicament can be to get rid of the burden on businesses quickly becomes lighter, enterprises can migrate data center entities to hybrid cloud computing infrastructure network, run by virtualization technology, and can also rely on the cloud calculation process to quickly resolve some of the problems, in conjunction with sophisticated software and related services, compared to the previous server and processing speed, cloud data center architecture can achieve high performance and stable operation at the same time. Companies will move to the cloud data center, in addition to can enjoy the same service entity data center, but also can bring considerable economic benefits, saving a lot of cost in the past must continue to pay. 
But cloud computing also not as easy to be accepted by users, there are different specific cultural factors, and other regulatory and business risk appetite will affect companies in different businesses, and cloud computing brings no privacy and sharing will affect the acceptance of this, and will therefore affect the implementation of cloud computing business planning. Many companies will choose to carry out further work on risk assessment of cloud computing can not be estimated in order to avoid losses.
Enterprises also need to understand their technology strategy, which is determined according to: whether the company plans to transfer most of its business to the cloud? Has the plan in this case selective use of cloud computing? These issues will affect whether companies will be willing to bear the risk of cloud computing number, especially corporate culture issues mentioned before. These are the challenges of cloud computing to the enterprise, companies need to put data on the cloud server which also need to be considered. 
As for how to choose a cloud computing service provider, we need to also consider the specific circumstances of service providers at the same time considering the needs of the self. First, the cloud data center infrastructure service provider must have excellent cloud computing network, which is to ensure smooth data transfer and will not appear any major security problems during transmission. Second, whether the cloud data center architecture there is enough space and flexibility, which is to allow users to select different deployment of cloud resources to meet their own needs. Finally, there is whether service providers of management software is simple enough to use, so that enterprises in the office can grasp all aspects of the data center, and can be read at any time, just as the same data center management entity.
We can say that cloud computing brings light treatment can successfully help enterprises in the low starting point can be obtained with mature companies equal services, although the current cloud computing is not yet mature, the current cloud computing industries are only emerging, the future of our cloud computing We have more expectations. At the same time, for the post-PC era veteran manufacturing giant Hewlett-Packard, Dell, cloud computing is to give them a chance of recovery. In general, cloud computing is a sea of blue, but also must be a win-win situation, and the future of cloud computing how to develop more worth the wait.
