 Cloud Proxies are special types of remote collectors that enable vRealize Operations Cloud to collect and monitor data from on-premises data centers. Cloud Proxies establish a one-way communication channel from the on-premises environment to the vRealize Operations Cloud, and they securely upload data to the cloud instance without requiring any inbound ports to be opened on the firewall. Cloud Proxies can support multiple vCenter Server accounts and other management packs, and they provide data persistence and high availability features12. References: 1: Configuring Cloud Proxies in vRealize Operations 2: Managing Cloud Proxies in vRealize Operations
