AWS Storage Fundamentals
Block, file and object storage, plus configuring S3, with boto3 examples and a services comparison.
Block storage is the most familiar type of storage for a system administrator, as it corresponds to how a traditional hard drive works. In AWS, the corresponding service is EBS (Elastic Block Storage).
EBS volumes are presented from arrays managed by AWS and exposed to EC2 instances as virtual disks. Multiple EBS volumes can be attached to the same EC2 instance, and in some cases an io1/io2 volume can be shared between multiple instances via EBS Multi-Attach.
Key principle: On an update, only the modified blocks are rewritten — not the entire file. This is the main advantage of block storage for I/O performance.
