= ROSA tested cluster maximums

Consider the following tested object maximums when you plan a {product-title} (ROSA) cluster installation. The table specifies the maximum limits for each tested type in a ROSA cluster.

These guidelines are based on a cluster of 102 compute (also known as worker) nodes in a multiple availability zone configuration. For smaller clusters, the maximums are lower.

= Control plane and infrastructure node sizing and scaling

When you install a {product-title} (ROSA) cluster, the sizing of the control plane and infrastructure nodes are automatically determined by the compute node count.

If you change the number of compute nodes in your cluster after installation, the Red Hat Site Reliability Engineering (SRE) team scales the control plane and infrastructure nodes as required to maintain cluster stability.
