I have a local Scalr deployment and I was following the 3 Tier Web App tutorial.
All steps work fine, but when I try to deploy the farm in AWS, all the machines get stuck after Cloud-init.
Here is the last line of the log
Cloud-init v. 0.7.5 finished at Mon, 27 Mar 2017 13:06:49 +0000. Datasource DataSourceEc2. Up 67.80 seconds
Then the machines stay like that indefinitely.
