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