Openshift and Openstack are cloud computing technologies developed by Red Hat Inc. Openstack turns servers into the cloud. It can automate resource allocation by giving customers access to virtual resources such as VPS, blockchain and object storage, among others.
Openshift, on the other hand, is a containerization technology that provides a platform as a service (PaaS). It is a framework that runs on various cloud services like AWS and Google Compute Engine, so developers can easily deploy and test their applications without having to deal with real servers.
You can run Openshift on top of an Openstack-supported cloud service if you want, but they are essentially independent products that can be used separately.
In this paper, we compare these two parameters.

Containerization support in Openstack is optional and is intended more for use as a VPS. In general, hypervisors such as Xem, VMware or KVM are used to run virtual machines on which containers can run.
Openshift is a framework built around containers. It takes the concepts of Kubernetes and packages them in a way that makes it easy for enterprises to build and deploy applications in the cloud.
Openstack itself is not an exclusively distributed system. Sure, you can take control of an entire data center with Openstack, but it won’t be as global as a Kubernetes cluster.
Again: Turning multiple remote Openstack installations into a single distributed system requires many additional layers of software.
Openshift, on the other hand, is an inherently distributed system because of its integration with Kubernetes. This means that the entire system has one or more master nodes that control different worker nodes. Red Hat also provides solid network support to facilitate communication between these nodes.

Openstack allows users to offer infrastructure as a service. You can manage servers and provide services that are typically outsourced to cloud VPSs such as AWS, Azure, DIgitalOcean, and Google Compute Engine. Openstack makes creating your own personal cloud much easier. All you have to do is buy the devices that meet your specific needs.
Openshift works according to a completely different concept – Platform-as-a-Service. It can containerize the application your company develops, making it much easier to create and deploy new projects in the field.
Users are now not required to run Openshift on Openstack, but can work together seamlessly if they choose to. Just as you start by allocating a VPS and installing Openshift on it before you start working on your applications, you can do the same with Openstack.
Users can also split applications between a public service and your private cloud. Openshift ensures that some parts of your application remain in the private cloud and the rest in the public service. This is achieved by explicitly telling Openstack to run data-related pods on private nodes.
These are two completely different technologies, with completely different tasks. Which one you choose depends solely on what you want to achieve.
If you want to create a personal cloud from a server, Openstack is the solution. If you are looking for a container-based framework as an alternative to Kubernetes, you can choose Openshift.
