    379379=== Demo 1: no Self-healing service ===
    380380
     381For testing purposes, we have also created a client application that requests temperature information from nodes running the appropriate service. The interval between requests has been arbitrarily been set at 2 seconds. In the screenshot, you may see that, when a node fails, the number of read values drops:

    381385=== Demo 2: Self-healing inside an island ===
    382386
     387In this second demo we will be starting the Self-healing service and repeat the node failure simulation.
     388
     389At the service's startup, it loads the config file and recognizes the resources that it needs to monitor:

     392
     393We repeat the node failure several times. In the screenshot you may see that node failure was repeated three times, but each time the self-healing service starts the service on a node to fill-in for the missing information. Only once the node failure was so close to the client's request that the latter could only read 1 value. The other times, the nodes were up again in time for the client to read enough values:

    383397=== Demo 3: Self-healing across islands ===
