  • Go to EC2 services

  • Select 'Add tags' and add a tag called Name equal to 'i2pc-volume-x' (replace x by your user number)
  • Click on 'Create Volume'
  • Set Volume size to 1 GB and Availability Zone to the one of your instance (IMPORTANT)

Attach a volume to an instance

  • Select your volume (named i2pc-training-volume-x)
  • Click on 'Actions' and select 'Attach volume'
  • Wait till it finishes attaching (refresh)
  • Go to your 'Instances' and start your instance (i2pc-machine-x)
