I would like to introduce open-source Waldur platform - targeted for openstack cloud operators and implementing service delivery pipeline towards end customers. It uses modular approach and has the following core features:

* integrated marketplace and self-service for the end users (REST API and webapp) * built-in accounting, integrations with backend billing systems and payment gateways * built-in customer support/servicedesk functionality and integrations with backend servicedesk systems (Atlassian Servicedesk for example) * built-in organisation membership and user management * multi-cloud (ie multiple openstack API endpoints) support inside customer project containers

This diagram provides overview about available modules and their relations: https://waldur.com/assets/doc/waldur-diagram.pdf

Waldur openstack support is fairly mature - it has been successfully used in production deployments since 2015. Its web-based self-service for end users implements somewhat opiniated openstack tenant and resource management - based on our real-world experience and some best practices delivered from it. But also Horizon access provisioning and out-of-band tenant changes sync are supported.

More details about Waldur platform and its openstack support can be found here: https://waldur.com/#openstack
