Hi ComfortableHorse5 ,
This is, as always a matter of effort and deployment. As a rule, it is very unlikely that you AWS storage (EBS) would "die" - usually, when your machine "dies" (for some reason), it is the EC2 instance - in that case, you simply spin up a new instance attached to the same EBS device. To protect against EBS device failure, you should have a periodic backup of your data (daily backup is a very good solution, but you can even do an hourly backup if you'd like) - there are many ways of accomplishing that on AWS.
As always, it is always a question of the effort you put into the deployment. For a fully scalable and state-of-the-art deployment, you can use our https://github.com/allegroai/clearml-server-k8s/tree/master/clearml-server-cloud-ready , but as always, that takes more time and effort to set up and maintain,
