Application Programming Interface.
Application
In WSO2 PPaaS, an application is referred to as a composite application for the purpose of grouping a set of cartridges together.
Artifact
An artifact is a deployable unit that is supported by a specific cartridge type (e.g., a PHP file in a PHP cartridge, a web app (.war) in an Application Server Cartridge).

The partitions.json file contains configurations on sample partitions.
Pod
In Kubernetes pods are the smallest deployable units that can be created, scheduled, and managed. For more information on pods, refer the Kubernetes documentation. When working with a worker manager cartridge, when an application is deployed in a Kubernetes setup, PPaaS will create pods for the required worker and manager nodes.
Region
A region demarcates a geographically separate area used to define one or more partitions. Thereby, regions provide geographical separation and redundancy.
