Elastic Block Store (EBS)

EBS Volumes

  • It’s a network drive (there might be a bit of latency)
  • It’s locked to an Availability Zone (AZ)
  • Have a provisioned capacity (size in GBs, and IOPS)
    • You get billed for all the provisioned capacity
    • You can increase the capacity of the drive over time
  • Delete on Termination attribute
    • Controls the EBS behaviour when an EC2 instance terminates
  • You don’t have to detach a volume or restart the instance to change it
  • Increase volume size (you can only increase, not decrease)
  • Change volume type
    • GP2 -> GP3
    • Specify desired IOPS or throughput performance (or it will guess)
  • Adjust performance (increase or decrease)
