Cloud computing--at least as an extension of virtualization--has become increasingly widespread. However, cloud computing does not yet support a complex enterprise environment. So the cloud computing architecture is clear, and experience suggests that before cloud computing matures, we should focus on the details of the system's cloud computing architecture. 　　Based on some existing cloud computing products analysis and personal experience, summed up a set of cloud computing architecture, cloud computing architecture can be divided into four layers. Cloud computing architecture--the display layer is primarily used to show users what they want in a friendly way, and it takes advantage of the middleware layer below ...

One, the charm of the management of cloud computing is that users can start using their ID card and credit card, but that's the problem.

A small mobile phone application, but all-encompassing, integration of this complex information content or functional logic. To let users get the best experience in the use, quickly grasp the application of the framework structure, the navigation design is an important link. The navigation of mobile apps is similar to the role of signposts or maps in the real world. It is the virtual framework of the application software, which has the function of indicating identity and recognizing the user. For example, as a signpost, navigation can be in use, locate where the user is currently, to highlight the current view of the user important features, tell users where to go, in different views and areas quickly cut ...
