VMware Cloud was designed from the ground up to be simple to consume, allowing your operations teams to focus higher up the stack and away from the undifferentiated heavy lifting associated with hardware infrastructure.
This means, the management, health, and lifecycle of the underlying hardware infrastructure (compute, network, and storage) is the responsibility of the VMware Cloud Provider. This includes lifecycle management of the VMware component stack and the adding and removing of physical hosts for scaling and maintenance purposes.
From your perspective as a consumer of the platform, your operational responsibilities and overall observability capabilities now begin at the VMware software layer, which includes ESXi, NSX, and vSAN. Capturing the appropriate metrics from these components in addition to your enterprise workloads will form the building blocks for achieving full-stack observability.
