  • Deployment procedure needs few minutes to finish. The user is constantly informed by viewing the logs aggregated from all the nodes of the application.

    • The total deployment time depends on the cloud infrastructure selected, as the spawning of new VMs might take more time in some IaaS.

    • Total time is also affected by the network delays between the cloud infrastructure and the docker registry that is used to fetch the components container image.

  • When deployment finishes all nodes turn green

    • On the instance list the application is shown as “DEPLOYED”.
