Cloud Concepts Flashcards
Provides developers and IT teams with secure, durable, highly-scalable object storage.
S3
File that does not change
Flat File
Folder in the cloud
bucket
If you write a new file and read it immediately afterwards you will be able to view that data.
Read after Write Consistency
RAW
If you update an EXISTING file or delete a file and read it immediately - you may get the oder version or you may not since changes to objects take a little bit of time to propagate.
Eventual Consistency for PUTS and DELETES of Existing files
Storage class to deliver object storage to on-premises AWS Outpost environments
S3 Outposts
S3 charges
Storage Requests Storage Management Pricing Data Transfer Pricing Transfer Acceleration Cross Region Replication
Enables fast, easy and secure transfer files over long distances between your end users and an S3 Bucket
Transfer Acceleration
What does Transfer Acceleration take advantage of
Amazon CloudFront’s globally distributed edge locations.
As data arrives at an edge location it is routed to S3 over an optimized network path
Transfer Acceleration employing Edge Location
You can use these to make entire S3 buckets public
Bucket Policies
S3 Versioning: Stores all versions of an object
including all writes and deletes
S3 Versioning: Great for
Backups
S3 Versioning: Once enabled, versioning cannot be disabled
Only Suspended
S3 Versioning: Does this with lifecycle rules
Integrates with them
S3 Versioning: to provide an additional layer of security use this
Multi-factor authentication
