S3 replication, S3 Storage Classes - Coggle Diagram
S3 replication
Replication
CRR - cross region replication
SRR - same region replication
atts
Must enable Versioning in source and destination buckets
Buckets can be in
different AWS accounts
Copying is asynchronous
Must give proper IAM permissions to S3
Note
Only new objects are replicated
To replicate existing objects, using S3 Batch Replication
Replicate existing objects
Replicate objects that failed replication
For Delete operations
relicate
delete markers
from source to target
Deletions with a version ID are not replicated
Usage
CRR
Low latency access
Replication across accounts
compliance
SRR
Log aggregation
Live replication between production and test accounts
S3 Storage Classes
S3 Glacier Storage Classes
S3 Glacier Flexible Retrieval
Expedited: 1 => 5 minutes
Standard: 3 to 5 hours
bulk: 5 to 12 hours - free retrieval cost
Minimum storage duration of 90 days
S3 Glacier Deep Archive
For long term storage
standard: 12hours, Bulk: 48 hours
minimum storage duration of 180 days
S3 Glacier Instant Retrieval
Milisecond retrieval => great for data accessed once a quarter
minimum storage duration of 90 days
Attrs
Low-cost object storage for archiving / backup
Price = price for storage + object retrieval cost
Standard - General Purpose
used for frequently accessed data
Low latency and high throughput
sustain 2 concurrent facility failures
Standard-Infrequent Access (IA)
Less frequently accessed
but requires rapid access when needed
Lower cost than S3 standard
but you will have a cost on retrieval
Use cases: Disater recovery, backups
Attrs
Move between classes manually
Move between classes by using S3 lifecycle configurations
Durability vs Availability
High durability => for all classes
Availability: Measures how readily available a service is
Varies depending on storage class
S3 Intelligent Tiering
Attrs
Small monthly monitoring and auto tiering fee
allow you to move objects automatically between Access Tiers based on usage patterns
There are no retrieval charges in S3 intelligent-Tiering
All Kinds
Freequent Access tier
Infrequent Access tier: objects not accessed for 30 days
Archive instant access tier: 90 days
Archive Access tier (optional): 90 days to 700+ days
Deep Archive Access tier (optional): 180 days to 700 days
One Zone-Infrequent Access
Storing secondary backup copies of on-premise data or data you can recreate
