To deploy a Petals ESB composed of several nodes, we should be able to deploy components and SAs on each node concurrently.
As Petals CLI is able to work with only one container at a time, we should be able to launch several Petals CLI in the same time on the same machine.
In script mode, as the connexion establishment must be done in the script file, we can imagine to execute several scripts concurrently with the same Petals CLI instance. But if we can launch several Petals CLI instances in the same time, the script files can be executed concurrently launching a Petals CLI instance by script file, delegating the concurrency to the execution shell.
