View source for OCI Foundations - Storage


== Introduction ==

Persistent Storage / Non-Persistent Storage
Local NVMe attached to an instance
Copied to a NAS -> Block Volume
File Storage -> 2 Compute Instances can share files/directories
Object Storage -> Photos, Videos, Log files typically accesible via HTTP

Data Migration Services:
* Data Transfer Disk: send disk to Oracle
* Data Transfer Appliance: send larger system
* Storage Gateway: on-premise

Durable: multiple copies

== Object Storage ==

* Ideal for unstructred/semi-structured data (photos, logs, etc)
* Regional, public service

* Objects: key/value pair + metadata
* Flat heireachy, unique name in namespace
* Namespace must have globally unique name
* Namespace -> Bucket -> Object

* https://objectstarage.us-sanjose-1.oraclecloud.com/n/intoracleohit/b/development/o/log.zip
** Namespace: intoracleohit
** Bucket: development
** Object: log.zip

Standard Tier (hot):
* Instantaneous retrieval
* Fast, immediate access
* Most recent copy
Infrequent Access Tier (cool):
* Min storage for 31 days
* Retrieval fees
* Lower storage cost
* eg for backups

Archive Storage Tier (cold):
* Seldom accessed
* Min retention requirement of 90 days
* Restore time: 1 hr
* Downloaded to standard tier in 24 hours
* remote tape access

Lifecycle Managhement, eg:
* After 30 days standard -> archive
* After 60 days, delete

Auto-tiering:
* Can move between Stanard and Infrequent Access tier to reduce costs.

Auto-versioning

Encryption:
* On by default
* Can specify your own keys
