vCloud Director allows you to quarantine files (vApp templates and media files) that users upload to the system. You can enable upload quarantine and use third-party tools (for example, a virus scanner) to process uploaded files before vCloud Director accepts them.

You can use any Java Message Service (JMS) client that understands the STOMP protocol to monitor and respond to messages from the vCloud Director quarantine service.

When an uploaded file is quarantined, a JMS broker sends a message to a request queue on a cloud cell. The receiver decides whether to accept or reject the upload by sending a message to a response queue.
