How is the cloud computing platform classified?

Cloud computing platform can be divided into 3 categories: data storage-oriented storage-type cloud platform, data processing-oriented computing cloud platform and computing and data storage processing integrated cloud computing platform. Cloud computing platform Services obvious features:

(1) Services everywhere users need only a computing device with basic computing power and an effective Internet connection to use the service anytime, anywhere. In this sense, any networked application has the potential to be a cloud computing platform.

(2) have access to the cost of users have the need to use the service, but do not have the independent provision of the service economic or technical conditions. For example, some companies need to perform large-scale operations on a regular basis, but it is not worth buying a computing device with large-scale computing power. By developing a customer base to allow multiple users to share the cost of supercomputers, the supercomputer enables its users to complete computing tasks with less cost without computing equipment.

(3) Users decide to use the cloud computing platform to provide computing power (including processor, memory, storage, network interface), but do not care about the user's application type. Users use the computing power provided by the cloud computing platform and take full account of the (technical and economic) constraints set by the cloud computing platform to develop colorful applications. Cloud computing platforms that meet the above conditions can be subdivided into infrastructure services (IaaS, such as online storage and database services), platform as services (PaaS, such as the amp virtual host and Java EE Application Server containers), and software as services (SaaS, For example, Google Docs). Many manufacturers mention cloud computing, often refer to distributed computing (distributed Computing), parallel Computing (parallecomputing), Grid computing (grid Computing), Practical computing (Utility Computing) and so on. In fact, users don't care about the variety of new terminology, they only care about the availability of a service and the cost of using the service. To be honest, these concepts are just the technical details that cloud-computing platform providers need to know when they create cloud computing platforms, and they can be thought of as cloud computing, but not the nature of cloud computing.
