Initially, the platform, the service vendor, establishes its own market differences based on the language it supports, such as Java or. NET, but in the end they continue to evolve to support multiple languages and, ultimately, the infrastructure that serves to support data storage, messaging, application services, and mobility. The market provides a variety of PAAs for developers. Although it seems that PAAs vendors are very similar, but there are many differences. Consider the types that can be controlled, and if so, developers can configure them on the infrastructure. Ideally, PAAs vendors manage all of the implementation ...

Cloud computing (cloud computing) is an internet-based computing method in which shared hardware and software resources and information can be provided on demand to computers and other devices. 　　Cloud is actually a metaphor of the internet and the Internet. The core idea of cloud computing is to manage and dispatch a large number of computing resources with network connection, and form a computing resource pool to serve the users on demand. A network that provides resources is called a "cloud." Narrow cloud computing refers to the delivery and making of IT infrastructure ...
