Cloud Base: Cloud computing services landing Hardware Guarantee

2010, the National Development and Reform Commission to identify cloud computing as a key development projects, while approving Beijing, Shanghai, Hangzhou, Shenzhen and Wuxi as the first batch of cloud computing five model cities, today, all over the built, under construction or will be built in the cloud computing base in the spring springing up. So what is cloud computing? What about cloud computing services?

Cloud computing is the development of distributed processing (distributed Computing), parallel processing (Parallel Computing) and Grid computing (grids Computing), which automatically splits large computational handlers into countless smaller subroutines through the network, A large system of multiple servers is calculated and analyzed to pass the processing results back to the user. With cloud computing technology, Web service providers can handle tens of millions of billions of dollars of information in a matter of seconds to achieve the same powerful network services as supercomputers.

The goal of the cloud computing system is to run on the PC, or stand-alone, personalized operations on a single server migrate to a large number of server "Clouds", which is responsible for processing the user's request and outputting the results, which is a system centered on data operation and processing.

Cloud computing consists primarily of SaaS, PaaS, and IaaS services at three levels.

SaaS (software-as-a-service): Software as services. It is a mode of providing software over the Internet, and instead of buying software, users hire web-based software to manage business activities.

PaaS (platform-as-a-Service): platform--services. PAAs actually refers to the software development platform as a service, in SaaS mode to submit to the user. Therefore, PAAs is also an application of the SaaS model. However, the advent of PAAs can accelerate the development of SaaS, especially the development of SaaS applications.

IaaS (infrastructure-as-a-Service): infrastructure is service. Users can get services from a sophisticated computer infrastructure over the Internet.

The core of cloud computing is to move the operation of the business to the cloud, to reduce the cost of individual enterprise users, so the cloud needs to support the data center, while the cloud computing platform needs to build on the basis of the hardware platform, only to build a large-scale cloud base, to ensure that the cloud services safe landing.
