In NSX Federation within a VMware Cloud Foundation (VCF) environment, the following components are essential:
* NSX Local Manager: Each site participating in NSX Federation has an NSX Local Manager, which manages site-specific networking and security policies.
* NSX Global Manager: This component provides centralized management and coordination across multiple NSX Local Managers, allowing for consistent policy application and network segmentation across sites.

In VMware Cloud Foundation, Lifecycle Manager within the SDDC Manager is responsible for managing the lifecycle of all components in a workload domain. This includes monitoring, upgrading, and patching ESXi hosts, vCenter, NSX, and other integrated components within the workload domain. After the new workload domain is deployed and configured, Lifecycle Manager ensures that the environment remains up-to-date and compliant with VMware's best practices, making it essential for ongoing maintenance and support.
