Storage and Content Delivery Services Flashcards
S3 = Simple Storage Service
Highly available storage service where objects are stored in buckets.
Main Features of S3
Essentially limitless storage capacity, set security settings at the object or bucket level, logs to track access, enable versioning to avoid loss of data
S3 Storage Classes
Standard, Intelligent Tiering, Infrequent Access, 1 Zone Infrequent Access, Glacier, Glacier Deep Archive, and Outposts
Elastic Block Store (EBS)
an EC2 storage device that is attached (or removed) from an instance (similar to a flash drive). Allows data to persist when the instance is not running, good for running a DB. Can only be attached to one instance in the AZ.
EC2 Instance Store
local storage that is physically attached to the host computer (and cannot be removed). The data is still lost when the instance stops, so it’s only recommended for temporary storage needs.
Elastic File System (EFS)
A serverless network file system that ONLY WORKS WITH LINUX.
Storage Gateway
A hybrid storage service, recommended for moving backups to the cloud.
Content Delivery Network (CDN)
A mechanism to deliver content quickly and efficiently based on geographic location
CloudFront
A CDN that delivers data globally with low latency. Uses Edge Locations to cache content. Great for static websites, and helps prevent attacks on your app
Global Accelerator
Sends your users through the Amazon Global Network when accessing your content, which improves latency and availability of single-region applications.
S3 Transfer Acceleration
Improves upload and download speeds to and from S3 buckets. Uses CloudFront’s Edge Locations and allows users to upload to a central bucket.
