S3 storage Flashcards
storage class to store your frequently accessed data that is important and not replaceable, stored across at least 3 AZ. 11 9’s durability
S3 Standard
used to detect and fix any data corruption
Cyclic Redundancy Checks
storing long-lived data where access is infrequent
S3 Standard-Infrequent Access
Standard-IA has a minimum duration charge of 30 days, even if objects are stored for less, you will be billed for the full 30 days
True
Storing long-lived, yet less frequently accessed data. Only stored in one AZ. Used for not important/replaceable data
S3 One Zone-IA
low-cost storage for data archiving and long-term backup suitable for files
that are rarely accessed and takes minutes to hours for object retrieval
Amazon S3 Glacier Flexible Retrieval
used for long-lived data accessed infrequently but needs immediate/millisecond access
Amazon S3 Glacier Instant Retrieval
glacier file retrieval in 1-5 minutes
Amazon S3 Glacier expedited retrieval
glacier file retrieval in 3-5 hours
Amazon S3 Glacier standard
glacier retrieval in 5-12 hours
Amazon S3 Glacier bulk
offers a more competitive price point than S3 Glacier if your primary requirement is a durable and secure long-term storage for large amounts of data
S3 Glacier Deep Archive
glacier object retrieval in 12 hours minimum
S3 Glacier Deep Archive Standard
glacier object retrieval in up to 48 hours
S3 Glacier Deep Archive Bulk
Storing data with changing or unknown access patterns that automatically moves objects between access tiers
S3 Intelligent Tiering
policies determine how your objects are stored in your S3 bucket and lets you transition your objects from one storage tier to another, usually to reduce storage cost or to archive an object
Lifecycle Policies
reverse automatic, asynchronous copying of objects across Amazon S3 buckets
s3 replication
used to copy objects across Amazon S3 buckets in different AWS Regions
Cross-Region Replication
Needed to replicate data across accounts as the role is not trusted by the destination bucket
Bucket Policy
Does versioning need to be turned on for s3 replication?
Yes
Is s3 replication retroactive?
No
Can you replicate objects in glacier or glacier deep archive?
No
Are deletes replicated between buckets?
No
replication for log aggregation
SRR
replication for prod and test sync
SRR
replication for reslience with strict sovereignty
SRR
replication for global resilence improvements
CRR
replication for lower latency
CRR
