EBS Performance Optimization

Pick the right EBS volume type, read the credit and exceeded-check metrics that explain slow storage, and tell the difference between a volume that is throttled and an instance that is.

Intermediate 28 minutes 5 Learning Objectives
  1. Explain how I/O size connects IOPS to throughput, and why a volume can hit one limit while the other is idle
  2. Compare gp2, gp3, io1, io2 Block Express, st1, and sc1 on their performance ceilings and provisioning models
  3. Calculate the burst duration of a gp2 volume from its size and credit balance
  4. Determine from CloudWatch metrics whether the volume or the instance is the constraint
  5. Modify a live volume's size, type, IOPS, and throughput with Elastic Volumes, and state the limits on doing so
