A cloud proxy is an appliance that enables vRealize Operations Cloud to collect and monitor data from the on-premises environment. A cloud proxy is deployed as an OVA template on a vCenter Server instance that manages the on-premises resources. A cloud proxy creates a one-way communication between the on-premises environment and vRealize Operations Cloud by uploading data from the remote collectors to the cloud service. A cloud proxy can support multiple vCenter Server accounts and other data sources that are configured in vRealize Operations Cloud1.

The other options are not appliances that are needed to achieve this goal. A reverse proxy is a server that receives requests from clients and forwards them to the origin server. A reverse proxy can provide security, load balancing, caching, and compression functions. A reverse proxy is not used to create a one-way communication between the on-premises environment and vRealize Operations Cloud2. A web proxy is a server that acts as an intermediary between a web browser and the internet. A web proxy can provide anonymity, filtering, caching, and security functions. A web proxy is not used to create a one-way communication between the on-premises environment and vRealize Operations Cloud3. A VMware proxy is not a valid appliance in vRealize Operations.
