Can Openshift be the right choice?

OpenShift is a platform for operating containers in a corporate environment. It facilitates the standardization of the operation of your applications and at the same time simplifies the operation and increases the safety and reliability of the operation. It allows you to assign selected permissions to, for example, supplier companies and thus have control over a larger part or the entire application development cycle. At the same time, it brings you a unified way of monitoring and collecting logs.
