A vhost, or virtual host, provides logical isolation by managing its own set of exchanges, queues, and bindings. This allows applications to run securely on different vhosts without interfering with each other. An instance can contain multiple vhosts, and a single vhost can contain multiple exchanges and queues. Producers and consumers must specify a vhost when connecting to ApsaraMQ for RabbitMQ.
Usage notes
You can delete a vhost only after deleting all its exchanges and queues, excluding the built-in exchanges.
