An instance is an independent Message Queue for RabbitMQ resource entity that includes basic resources such as virtual hosts (vhosts), exchanges, and queues. This topic describes how to create an instance, view instance details, upgrade an instance, downgrade an instance, and renew an instance in the Message Queue for RabbitMQ console.
