OCI FinOps - Expert Knowledge

NEVER Do This

NEVER terminate instances without --preserve-boot-volume false

# DEFAULT OCI behavior: boot volume PRESERVED after instance termination
oci compute instance terminate --instance-id <ocid> --force
# Instance gone, but boot volume keeps charging at $0.025/GB/month FOREVER

# RIGHT: explicitly delete boot volume
oci compute instance terminate \
  --instance-id <ocid> \
  --preserve-boot-volume false
