-## SAAS - Private Cloud Gateway (PCG)

-
-Palette supports on-prem environments through the Private Cloud Gateway (PCG) component. PCG provides support for isolated private cloud or data center environments. When installed on-prem, PCG registers itself with Palette, allowing for secure communication between the SaaS portal and the private cloud environment. The gateway also enables end-to-end lifecycle management of Kubernetes clusters in private cloud environments directly from the SaaS portal.
