Can be thought of as a USB being able to write the bytes in a file
Amazon EBS enables you to createindividualstorage volumes and attachthemto an Amazon EC2 instance
Volumes are automatically replicated for redundancy within its Availability Zone by default
Amazon EBS offers block-level storage
It can be backed up automatically to Amazon S3 through snapshots
io2 and io3 (Provisioned IOPS) are the only volume types that can be attached to two instances simultaneously. All of the other options can only be attached to one
Snapshots
Point-in-time snapshots
Recreate a new volume at any time
If you accidentally delete a resource like a snapshot, it will be kept for some time in the Recycle Bin. A retention rule must be created
This can only be done for storage EBS and AMI's
Encryption
Encrypted Amazon EBS volumes
No additional costs
Elasticity
Increase capacity
Change to different types
Volumes
EBS volumes persist independently from the instance.
Charges you by the amount you provision in GB per month until you release the storage
IOPS –
General Purpose SSD:
Charges you by the amount you provision in GB per month until storage is released.
Magnetic
Charged by the number of requests to the volume
Provisioned IOP SSD
Charged by the amount that you provision in IOPS (multiplied by the percentage of days that you provision for the month)
Snapshots
Added cost of Amazon EBS snapshots to Amazon S3 is per GB-month of data stored
Data Trandfers
Inbound data transfer is free.
Outbound data transfer across Regions incurs charges
Amazon S3 Standard•
Amazon S3 Intelligent-Tiering
Amazon S3 Standard-Infrequent Access (Amazon S3 Standard-IA)
Amazon S3 One Zone-Infrequent Access (Amazon S3 One Zone-IA)
Amazon S3 Glacier
Amazon S3 Glacier Deep Archive
The bucket name must be globally unique; you cant use underscores for the name
Amazon S3 buckets are associated with a Region
The bucket is redundantly stored across multiple AWS facilities within your selected Region.
Built to be durable even if two AWS facilities go down
The durability is built for 11 9's (99.99999999999)
Means you will lose 1 file in a year if its multiple terabytes
Amazon S3 automatically manages the storage behind your bucket while your data grows. You can get started immediately, and your data storage will grow with your application needs
It scales to handle a high volume of requests. You do not need to provision the storage or throughput, and you are billed only for what you use
Storing application assets
Static web hosting
Backup and disaster recovery (DR)
Staging area for big data
AWS Pricing
Storage class type
Standard storage is designed for:
11 9s of durability
Four 9s of availability
S3 Standard-Infrequent Access (S-IA) is designed for:
11 9s of durability
Three 9s of availability
Amount of Storage
The number and size of objects
Requests
The number and type of requests (GET, PUT, COPY)
Different rates for GET requests than other requests
Data Transfer
Pricing is based on the amount of data that is transferred out of the Amazon S3 Region
Data transfer is free, but you incur charges for data that is transferred out
Data transferred in FREE ; transferred out NOT FREE
Amazon EFS is
File storage in the AWS Cloud
•Works well for big data and analytics, media processing workflows, content management, web serving, and home directories
•Petabyte-scale, low-latency file system
•Shared storage
•Elastic capacity
•Supports Network File System (NFS) versions 4.0 and 4.1 (NFSv4)
•Compatible with all Linux-based AMIs for Amazon EC2
Amazon EFS provides file storage in the cloud. With Amazon EFS, you can create a file system, mount the file system on an Amazon EC2 instance, and then read and write data from to and from your file system.
Every availability zone will have a mount point. We can then connect it to an instance that belongs to your VPC subnet
Used for long-term and archive data.
