 2. {product-title} and Kubernetes are sensitive to disk performance, and faster storage is recommended, particularly for etcd on the control plane nodes which require a 10 ms p99 fsync duration. Note that on many cloud platforms, storage size and IOPS scale together, so you might need to over-allocate storage volume to obtain sufficient performance.
 3. As with all user-provisioned installations, if you choose to use {op-system-base} compute machines in your cluster, you take responsibility for all operating system life cycle management and maintenance, including performing system updates, applying patches, and completing all other required tasks. Use of {op-system-base} 7 compute machines is deprecated and planned for removal in a future release of {product-title} 4.
