Cloud servers are increasingly respected by more and more users for their simplicity, efficiency, security, reliability, elasticity and other characteristics, for cloud servers are mainly carrying a few sides of the work, the functional level: to provide enterprises with IaaS layer of hardware resources, including distributed storage of data, distributed computing, etc.; the resource level: to provide dynamic management of resource integration, for the PaaS level to provide the relevant resources **** enjoyment! The service, compared to physical servers for enterprise users do not need to buy their own solid-state application server hardware in advance but to pay the annual fee model for cloud server leasing, although the cloud server on the one hand effectively reduces the cost of IT operations and maintenance, but at the same time, the enterprise's core data is also exposed to the outside world there is a hidden danger of data security.

With the trend of enterprises going to the cloud, more and more application software to put forward their own cloud domain software platform such as: Mingyuan cloud, Panmicro cloud, Kingdee cloud, etc., in order to solve the security risks of data exposure cloud servers are also derived from the original public cloud, private cloud, hybrid cloud, and other forms, but along with the cloud form of the evolution of the cloud, the "cloud silo, cloud vertical wells

In summary: cloud servers are indeed able to flexibly adapt, elasticity and scalability to effectively solve the difficulty of IT server operation and maintenance management, but enterprises need to face the cloud at the same time, choose wisely, do not blindly follow the trend, while taking into account the integration of cloud integration and data docking mode and standard management, to avoid just the physical application of the conversion mode of deployment and not from the fundamental solution to the actual data management and control of the enterprise's stated requirements.
