Host-level hardware and OS management including kernel patches, hardware failure handling, and network interfaces. This layer is managed by the host — you typically never need direct terminal access for these tasks
Automatic update pipeline for the operating system and core server software, controlled on the host's schedule. Note that application-level updates (for example, WordPress plugins or themes) may follow different schedules depending on your provider
