S3 Storage Classes Flashcards
Used to detect and fix any data corruption
Cyclic Redundancy Checks
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
Storage class to store 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
Storage class to store 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
Bridge between on-premises data and cloud data
used for:
- disaster recovery
- backup & restore
- tiered storage
- on-premises cache & low-latency files access
AWS Storage Gateway
Configured S3 buckets are accessible using the NFS and SMB protocol with most recently used data is cached in the file gateway
Amazon S3 File Gateway
Does SMB Protocol have integration with Active Directory (AD) for user authentication?
Yes
Native access to Amazon FSx for Windows File Server with a local cache for frequently accessed data
Amazon FSx File Gateway
Block storage using iSCSI protocol backed by S3 backed by EBS snapshots
Volume Gateway
Low latency access to most recent data in Volume Gateway
Cached volumes
Entire dataset is on-premise, scheduled backups to S3 in Volume Gateway
Stored volumes
Backup processes using physical tapes with a Virtual Tape Library (VTL) backed by Amazon S3 and Glacier
Tape Gateway
On-premises virtualization helpful for daily NFS backups in small data centers
Storage Gateway – Hardware appliance
A fully-managed service for file transfers into and out of Amazon S3 or Amazon EFS using the FTP protocol
AWS Transfer Family
AWS Transfer for FTP (File Transfer Protocol (FTP))
AWS Transfer for FTPS (File Transfer Protocol over SSL (FTPS))
AWS Transfer for SFTP (Secure File Transfer Protocol (SFTP))
on top of Amazon S3 or Amazon EFS
AWS Transfer Family
Move large amount of data to and from on-premises / other cloud to AWS or AWS to AWS
AWS DataSync
If moving large amount of data to and from On-premises / other cloud to AWS is an agent required?
Yes
Are File permissions and metadata preserved in AWS DataSync
Yes
