storage types

Block Storage

instance store (data lives with the instance)

block storage physically attached to instances

optimized

• speed

• not persistence

Elastic Block Store (EBS)

persistence - data can outlive the instance

(default deleted)

single availability zone

roll-back to previous snapshot

EBS multi-attach

• attach EBS to multiple instances

Object Storage

object storage = access via api

not file storage = nfs / smb

Object vs Block

object: if you make a 1 pixel change, the whole object is changed

block: if you make a 1 pixel change, the block containing that pixel is changed

Simple Storage Service (S3)

S3 storage classes

• Standard

• Standard IA (Infrequent Access)

• Standard One Zone IA (Infrequent Access)

• Intelligent Tiering

• Glacier Instant Retrieval

• Glacier Flexible Retrieval

• Glacier Deep Archive

File Storage

Elastic File System (EFS)

nfs or smb

Database types

Relational Database Service (RDS)

can imitate api of: mysql XOR postgres

why? (why not mysql / postgres

• it's faster

• integration with AWS services

Nonrelational

aka "NoSQL"

aka "Key-Value"

DynamoDB

serverless

key-value / nosql

10 trillion requests / day

Database Migration Service (DMS)
