Unlike the SSU, they're distributed separately from the regular CUs. In that case, always install/integrate the SSU before engaging with the CU. Power users or system admins may still prefer to deal with the CAB variant for ease of deployment. The servicing stack is the code that installs other operating system updates, hence Microsoft usually bundles them with CUs before publishing a standalone MSU package. In some cases, you might need to apply a Servicing Stack Update (SSU) before installing the newest Cumulative Update (CU). Since they're cumulative in nature, the latest rollup package can update the target Windows version to thce most recent build, regardless of what the previous build number was.

The primary focus of this index is centered around the Cumulative Updates (also known as Monthly Rollups), which include both security and reliability updates that are packaged together.
