Cloud platform refers to hardware-based services that provide computing, network and storage capabilities.
Cloud computing platforms can be divided into 3 categories:
1. Storage cloud platforms that focus on data storage;
2. A computing cloud platform focusing on data processing;
3. A comprehensive cloud computing platform that takes into account both computing and data storage and processing.
Service types of cloud platform
(1) Software as a service
Software as a service applications run entirely in the cloud. Software as a service is oriented to users and provides stable online application software. What users purchase is the right to use the software, not the ownership of the software. Users only need to use the network interface to access the application software. For average users, they usually use a simple client like a browser. The most popular software-as-a-service application today is probably Salesforce.corn, but there are many others like it. The vendor's servers are virtually partitioned to meet the application needs of different customers. For customers, the software-as-a-service approach does not require upfront investment in servers and software. For application developers, only one version of the application needs to be maintained for a large number of customers.
(2) Platform as a Service
The meaning of platform as a service is that a cloud platform provides cloud services for application development instead of building its own client infrastructure. For example, a developer of a new software-as-application service conducts research and development on a cloud platform. The direct users of the cloud platform are developers rather than ordinary users. It provides developers with a stable development environment.
(3) Additional services
Each locally installed application itself can provide useful functions to users, and an application can sometimes access the cloud Special application services in it to enhance functionality. Because these services only work for specific applications, they can be considered an add-on service. Take Apple's iTunes, for example. The client's desktop application is very useful for playing music and other basic functions, and an add-on service allows users to purchase audio and video on this basis. Microsoft's hosting service provides an enterprise-level example of providing additional services to the locally installed exchange service by adding other cloud-based functions (such as spam filtering, archiving, etc.).
