Around OCI Object Storage : Main concepts

Today, let’s talk about the categories of OCI Object Storage Tiers.

First let’s check some basic concepts around OCI Object Storage . The Object storage service is one of the OCI storage services , like , Block Volume , File Storage ..

The particularity of OCI Object Storage is that provides reliable, secure, and scalable object storage. It’s highly durable and cost efficient, and designed for unstructured data, supports private access from OCI resources in a VCN(Virtual Cloud Network).

It’s a storage architecture that stores and manages data as objects

There are two options at bucket creation level with respect to storage tiers:

1. Standard Storage tier bucket : which contain objects with different storage tier assignments.
2. Archive storage tier bucket: Only contain objects with an archive storage tier assignment.

Also we differentiate 3 types for the storage tiers , here the list and the characteristics for each type:

1. Standard : It’ s a default storage tier, and used for data that you need to access quickly, immediately and frequently.
   • Need to consider that the cost is more higher comparing to the other tiers.
   • Auto-tiering is enabled.
   • There are no retrieval charges and no retention requirements.
2. Cool Tier (Infrequent Access Storage Tier) : Access to data infrequently.
   • Storage costs are lower than standard.
   • Minimum retention period is : 31 days.
   • When you need to access objects , you are charged a per GB data retrieval fees.
   • Use case : Backup of on-prem datas.
3. Archive Storage Tier : For data that must retained for long periods of time.
   • It contain only objects with archive storage tier assignment.
   • Has a lowest storage cost.
   • To restore the objects, they must be restored and returned to the standard tier before they are available for access.
   • Minimum storage retention period is : 90 days .

Best Practice !

It’s recommend to use CLI , SDK or API for larger files , instead of , using the console to upload objects.
Why?
Object storage supports uploading files up to 10TiB , the memory capacity and browser capability can have an impact on uploading files on bucket.
