At any point of time, any Hardware Node and Container is characterized by a status (or state).
A Hardware Node may have two statuses only:
'online'
meaning that the Node is up and running and
'offline'
meaning that the Node is down.
A Container, in its turn, may have five stable statuses and a number of transitional statuses. If the Container is in one of the stable states, it means that it is likely to continue in this state until its administrator performs a task that would change its status. If the Container is in one of the transitional states, it means that it is currently passing from one stable state to another. During a transition stage, no operation can be performed on the Container until the transition is finished.
The stable statuses are:
