This chapter describes node design options that enable you to build a cluster for a wide range of workload-handling capabilities, expanding on the information provided in Technology and Deployment Process Overview. Usually, the platform design process ensures that the OpenShift Container Platform 4.3 cluster can meet initial workloads. The cluster must also be capable of being scaled out as the demand for workload handling grows. With a clear understanding of your workloads, it is easier to approach CPU sizing, memory configuration, network bandwidth capacity specification, and storage needs. Many operational factors can affect how the complexity of a container ecosystem affects operational latencies. Best practice is to add a safety margin to all physical resource estimates. Our goal in providing this information is to help you get Day-2 operations underway as smoothly as possible.
