Generic locker to give identity to machines in an AWS ASG

Shantanu,

Let’s sketch out an usecase that I think should address the simpler scenario where:

  1. You have a spotfleet on AWS
  2. You maintain external EBS volume(s) per instance in the spotfleet that have the state
  3. When spotfleet gets a termination recommendation or notice, you immediately start to drain the old one and spin up a new node
  4. When that new node comes up, you setup (using userdata) with the same “node specific” metadata and attach the relevant external EBS volume(s)
  5. You essentially have migrated the old node to the new node

Does this properly capture your usecase we can work on or did I lose details/context in the translation?
