EC2 Instance Storage - Coggle Diagram

- - - - 1000s of concurrent NFS clients, 10GB+ /s throughput
      - Grow to Petabyte-scale network file system, automatically
    - - set at creation time
      - latency sensitive use cases (web server, CMS, etc)
      - max I/O - higher latency, throughput, highly parallel (big data, media processing)
    - - Bursting
      - Provisioned: set your throughput regardless of the storage size
      - Storage Tiers (life cycle management - move file after N days)
        
        Standard: for frequently accessed files
        
        Infrequent access (EFS-IA): cost to retrieve files, lower price to store
- - - - Combining 2 or more volumes and getting the total disk space and I/O
      - If one disk fails, all the data is failed
      - Use cases
        
        application that needs a lot of IOPS and doesn't need fault-tolerance
        
        a database that has replication already built-in
      - Using this, can have a very big disk with a lot of IOPS
    - - Same as RAID 1 - except that here it writes to all the volumes below logical volume
- - - - Cost effective storage, low-latency
      - System boot volumes, virtual desktops, development and test environments
      - 1 Gb to 16 Tb
      - gp3: baseline 3000 IOPS and throughput of 125 MiB/s; can increase IOPS up to 16,000 and throughput up to 1000 Mib/s independently
      - gp2: Small gp2 volumes can burst IOPS to 3,000; size and volume of IOPS are linked, max IOPS is 16,000; 3 IOPS per GB, means at 5334 GB we are at the max IOPS
  - - - Provisioned IOPS (PIOPS) SSD
        
        Critical business applications with sustained IOPS performance
        
        Apps which need more than 16,000 IOPS
        
        Great for database work loads (sensitive to perf and consistency)
        
        io1/io2 (4GB-16TB): max PIOPS independently from storage size; can increase PIOPS independently from storage size; io2 have more durability and more IOPS per GB
        
        io2 Block Express (4GB - 64TB): Sub-millisecond latency; Max PIOPS: 256,000 with an IOPS:GB ratio of 1,000:1
      - Supports EBS multi attach
  - - - 125 MB to 16TB
      - Throughput optimized HDD (st 1)
        
        Big Data, Data Warehouse, Log processing
        
        max throughput 500Mb/s - max IOPS 500
      - Cannot be a boot volume
      - Cold HDD (sc 1)
