Chapter 1. Purpose of this document In this document, we offer a validated, private cloud solution for running Red Hat OpenShift Container Platform 4.12 on Red Hat OpenStack Platform 16.2. Red Hat OpenShift Container Platform, Red Hat OpenStack Platform, and Red Hat Ceph Storage are the key architecture components of our solution. This document is not an implementation guide, but a supplement to product documentation. You can find complete, supported, and fully tested individual product documentation for all three architecture components in the Additional documentation links section. 1.1. Red Hat tested solution This document presents our recommended practices for an OpenShift on OpenStack solution. We analyse each component and explain the options. We then highlight that selection for implementation. All recommendations made are tested together, in a lab, by Red Hat's OpenShift on OpenStack Quality Engineering (QE) team. This document reflects a truly working and tested solution. For specific implementation steps and procedures, Red Hat product documentation has the details required for a successful deployment. Combined with the review and testing assurances from this solution document, we are able to provide a holistic and practical solution to form the basis of any OpenShift on OpenStack implementation. 1.1.1. Scaling and Performance Testing While all efforts have been made to evaluate the solution against real world scenarios, we are unable to test against every possibility. You should view this solution as a baseline for deployment and it is recommended that you perform comprehensive performance testing for your specific workloads and usage patterns. Control plane nodes should be sized carefully according to expected cluster size and growth and storage solutions implemented and tuned accordingly. Where possible, this document has been updated to reflect customer experiences under real world conditions, combined with the best solutions from our global engineering and services teams. For more information, see Recommended infrastructure practices or speak to your Red Hat account team. 1.2. OpenShift on OpenStack simplifies your cloud native journey Red Hat's tested solution for implementing OpenShift on OpenStack is a key component in simplifying your cloud native journey. We have engineered and fully tested the solution across both OpenShift and OpenStack to ensure reliability and interoperability. We support both platforms and ensure they work together to give you a flexible, production-grade foundation supporting your organization throughout your modernization journey and beyond. Running OpenShift on OpenStack will assist your business to: Migrate workloads over time. Running Red Hat OpenShift on Red Hat OpenStack Platform gives you the flexibility to run both virtualized and containerized applications side by side on the same integrated, supported foundation, helping to make migration and transformation projects easier. Build cloud-native skills and accelerate DevOps practices. By combining containers and virtual machines in a consistent solution IT operations staff and developers work in a unified platform helping teams to grow and develop cloud-native processes and methodologies together. Access proven expertise and support across both platforms. We support both platforms, simplifying and streamlining issue resolution with a single point of contact. Plus, we offer services and training to help your organization develop the practices, tools, and culture needed to more efficiently modernize existing applications and build new cloud-native ones.
