@MaofujitaU17521616 no, you can’t install a VDI product on Pega Cloud, since it’s a managed platform and you don’t get OS or desktop control. Pega Cloud runs Pega Platform and Robot Manager; the actual RPA robots must run on Windows machines you manage, either on-prem, in your own cloud, or inside your existing VDI like Citrix or Horizon. You trigger and monitor those robots from Pega Cloud using Robot Manager work queues or APIs. Network-wise, allow outbound HTTPS 443 from the robot hosts to your Pega Cloud URL; if you need private paths, use your VPN or private connectivity options supported by Pega Cloud. For unattended work, stand up a pool of Windows VMs in your VDI or server farm, install Robot Runtime and RPA Service, and size concurrency by queue load. Keep the target business apps reachable from those VMs so UI automation is stable and low latency. For attended use, install Robot Runtime on users’ VDI desktops and register them to Robot Manager. You own patching, images, credentials, and monitoring of the robot hosts; Pega Cloud does not manage that layer. If you want everything in cloud, host Windows robots in your Azure or AWS account or a managed VDI service and link them to Pega Cloud.
