What is paas

PaaS stands for Platform-as-a-Service. A business model that provides a server platform as a service. The service of program provision through the network is called SaaS (Software as a Service), and the corresponding server platform or development environment in the era of cloud computing as a service to provide has become PaaS (Platform as a Service).

Features

PaaS can integrate various existing business capabilities, which can be specifically categorized as application servers, business capability access, business engines, business open platforms, and down according to the needs of the business ability to measure the basic service capabilities, call hardware resources through the API provided by the IaaS. The PaaS has the following three main features:

(1) Platform as a service: the most fundamental difference between the services provided by PaaS and other services is that PaaS provides a basic platform rather than a certain kind of application. In the traditional concept, the platform is the basis for providing services to the outside world. Generally speaking, the platform, as the basis for the deployment of application systems, is built and maintained by application service providers, while PaaS subverts this concept by specialized platform service providers to build and operate this basic platform, and to provide this platform as a service to the application system operators;

(2) Platform and services:The services that PaaS operators need to provide are not only purely the PaaS operators need to provide services, not only the basic platform, but also include technical support services for the platform, and even for the platform for the application system development, optimization and other services.PaaS operators know the most about the basic platform they operate, so the PaaS operators proposed by the application system optimization and improvement of the proposal is also very important. In the development of new applications, the PaaS operator's technical consulting and support team's intervention is also an important factor to ensure that the application system can be operated for a long period of time and stably in the future operation;

(3) Platform and services:The services provided by PaaS operators are different from other services, and the backbone of such services is the powerful and stable basic operation platform, as well as the professional technical support team. technical support team. This "platform-level" services to ensure that support SaaS or other software service providers of various applications for a long time, stable operation. the essence of PaaS is to serve the Internet resources into programmable interfaces for third-party developers to provide commercially valuable resources and services platform. With the support of the PaaS platform, the developers of cloud computing [2] have access to a large number of programmable elements, which have specific business logic, which brings great convenience to the development, not only improves the development efficiency, but also saves the development cost. With the support of the PaaS platform, the development of WEB applications has become more agile, the ability to quickly respond to the user's needs for development, but also for the end user to bring tangible benefits.

3PaaS Difference Editor

Simply put, a PaaS platform refers to an application infrastructure service in a cloud environment, which can also be described as middleware-as-a-service.PaaS platforms are located in the middle tier of a cloud architecture, with SaaS at the top and IaaS at the bottom [3]. In traditional On-Premise deployments, the application infrastructure i.e. middleware is very diverse with application servers, databases, ESBs, BPM, Portal, messaging middleware, remote object invocation middleware and so on. For PaaS platform, Gartner divided them into two categories, one is the application deployment and operation platform APaaS (application platform as a service), the other is the integration platform IPaaS (integration as a service). People often say PaaS platform basically refers to APaaS, such as Force and Google App Engine.

The China Cloud Application Platform, which was recently launched on the domestic market, can provide software vendors with a leading IaaS infrastructure platform, enabling software vendors to focus their attention on the cloudization of their application products and the demand for basic resources, including cloud servers, cloud storage, cloud monitoring and so on. The cloud server, cloud storage, cloud monitoring, etc. are completely dependent on the concept of leading, mature technology, safe and reliable IaaS platform.

China's cloud application platform will join the stationed traditional software to SaaS software transformation, the use of traditional software combined with cloud computing IaaS model, and gradually realize multi-tenant single instance application architecture to ultimately achieve high-performance applications. In the future, a large number of traditional software companies in the process of cooperation with Huayun Data, through the integration with the PaaS platform, can quickly realize the cloud and SaaS transformation.
