  1. EBS
    1. Elastic Block Store
    2. storage volumes with ec2
    3. virtual hard disk
    4. types
      1. general purpose ssd - gp2
        1. 3 IOPS per GiB, up to 16000 IOPS per volume
      2. general purpose ssd - gp3
        1. 3000 IOPS, 125 MiB/s regardless of volume size
        2. can scale up to 16000 IOPS
      3. provisioned IOPS SSD - io1
        1. up to 64000 IOPS per volumn. 50 IOPS per GiB
        2. high performance / mose expensive
      4. provisioned IOPS SSD - io2
        1. latest
        2. higher durability and more IOPS

        notion image
      5. Throughput Optimized HDD - st1
        1. hardware
        2. low-cost
        3. 40 MB/s per TB, up to 250 MB/s per TB
        4. max 500 MB/s per volume

        3. max 250 MB/s per volume
        4. cannot be a boot volume
        notion image
    5. diff between IOPS and throughput
      1. IOPS: times
      2. Throughput: number of bits
  1. volumes
    1. volume exist on EBS
  1. snapshot
    1. exist on s3
    2. are incremental
    3. consistent snapshots: stop the instance and take a snap
    4. share only in the same region
    5. exist on the same AZ as EC2
    6. can resize on the fly
    7. can switch volume on the fly
  1. encrpte
    1. AES-256

    1. safe info from memory to disk
    2. do not need to reload the operating system
    3. RAM must be less than 150GB
  1. EFS
    1. Elastic File System
    2. content management
    3. use NFSv4 protocol
    4. 1000s Concurrent Connections
    5. 10 Gbps Throughput

    1. file system
    2. based on Windows server
  1. AMI: Amazon Machine Image
  1. EBS vs Instance Store
    1. Instance Store: ephemeral storage
    2. EBS can be stoped, IS cannot
  1. platform
    1. EFS: linux
    2. FSx: Windows
    3. FSx for Lustre:
