PaaS

Platform as a Service (abbreviated as PaaS) is a platform for developing software delivered as a service, where development can take place either online or offline.
In the latter case, the developer, after downloading part of the platform, can develop the software within their own infrastructure and upload it through synchronization with the public platform.
PaaS service providers allow the publication and sale of the software developed within the Cloud platform.

Some use case scenarios for the PaaS model:

• Development frameworks.
  The PaaS model provides a framework that developers can use to build or customize cloud-based applications. Much like creating an Excel macro, a PaaS solution allows developers to create applications using integrated software components. Cloud features such as scalability, high availability, and multi-tenancy are included, reducing the amount of code developers need to write.
• Analytics or business intelligence.
  Tools provided as a service with a PaaS solution enable organizations to analyze data and perform data mining operations, uncovering insights and patterns, and predicting outcomes to improve forecasting, product design decisions, ROI, and other business decisions.
• Additional services.
  PaaS solution providers may offer other services that enhance applications, such as workflow, directories, security, and scheduling.
