Systems and Methods for Generation of a Tenant-Specific Service for a Software-As-A-Service Platform

Technologies are provided for generation of an executable package that provides a tenant-specific service. Generation of the executable package can be based on customization assets and a core codebase. The core codebase can define core modules that provide a core service that is common across tenants. Each core module includes one or multiple extension points. The customizations can be defined within one or multiple virtual partitions, where a virtual partition includes a filesystem or another type of non-transitory storage structure. The VP can include multiple customization resources and customization components. The customizations can permit building extension modules that can be mapped onto respective extension points of core module(s) in order to customize the common core service and yield the tenant-specific service. The core codebase can be built to generate built core modules. The executable package can be formed by combining built extension modules and built core modules.
