Platform9's Managed OpenStack enables users to deploy and operate OpenStack Hybrid Cloud with a 100% SaaS based service. The SaaS platform lets users go live with an OpenStack private cloud with its deployment tools. The Platform9 dashboard is designed to offer visibility into infrastructure across compute, storage, network, and existing workloads.
If you're having OnPremise Infrastructure and you want to use OpenStack in that case Platform9 Managed OpenStack is recommended to use it will cut down all the complexities of setting up and managing OpenStack IaaS. Platform9 also offers setting up OpenStack on Cloud Such as AWS, GCP, and Azure but wouldn't recommend using this kind of offering as Openstack performs well when underneath virtualized infrastructure is backed directly hypervisors not cloud providers.
