Platform as a Service (PaaS) is a cloud service in which the cloud provider provides the user with a development environment in the form of a framework with which companies accelerate their app developments.
With the cloud service Platform as a Service (PaaS) and the programming interfaces provided therein, developers can be offered entire development environments with databases, middleware and application software via cloud computing. Corresponding platforms are used for the management and storage of large amounts of data. This should be particularly interesting for the development of web applications, because it provides users with an infrastructure for the development of high- performance PHP applications. In addition, the aPaaS platform, Application Platform as a Service (aPaaS), provides an application-oriented platform for newcomers, start-ups and less experienced developers.
The user can access the corresponding framework via the Internet using standardized interfaces. He always has the latest versions, does not need to worry about upgrades and has no downloads or installations. As with other cloud service models, billing for the PaaS service is based on usage. Disadvantages could arise if the user uses proprietary programming languages that the cloud provider cannot provide.
Since some applications involve highly sensitive data from the banking sector, Platform as a Service (PaaS) is increasingly being offered as a more open version, as a Public Platform as a Service, Public PaaS, and as a closed Private Platform as a Service, Private PaaS.
There is a wide range of PaaS services: Traditional development platforms but also low- code/no-code( LCNC) platforms to develop business applications or business functions. Salesforce, Microsoft Force.com and Google, among others, offer PaaS offerings for many commercial applications.
