S3
Simple Storage Service is an object storage service for the cloud that is highly available
- backup and restore
- data lakes
- archival solutions
S3 Standard
- General purpose storage
- Data stored across multiple availability zones
- Low latency and high throughput

- per GB/month storage fee
- data egress (outbound data)
Recommend for:
- Frequently accessed data
Durability: 99.999999999 %
Availability: 99.99%
S3 Intelligent-Tiering
- Automatically moves your data to the most cost-effective storage class

Availability: 99.9 %
S3 Standard-Infrequent Access (IA)
- Data accessed less frequently but requires rapid access
- Data stored across multiple Availability Zones
- Cheaper than S3 standard
Recommended for:

- Infrequently accessed
- Millisecond access when needed
Durability: 99.999999999%
Availability: 99.9%
S3 One Zone-Infrequent Access (IA)
- Like S3 Standard-IA but data stored in a single Availability Zone
- Costs 20% less than S3 Standard-IA
- Data stored in this storage class can be lost
Recommended for:
- Re-creatable data
- Infrequently accessed with millisecond access
- Availability and durability not essential
Durability: 99.999999999%
Availability: 99.5%
S3 Glacier
- Long-term data storage and archival for lower costs
- Data retrieval takes longer
- 3 retrieval options: Expedited 1-5 minutes, Standard 3-5 hours, or Bulk 5-12 hours
- Data stored across multiple Availability Zones
Pricing
- per GB/month
- retrieval requests
- quantity
- data transfer out
Recommended for:
- Long-term backups
- Cheaper storage options
S3 Glacier Deep Archive
- Like S3 Glacier but longer access times
- 2 retrieval options: 12 hours or 48 hours
- Cheapest of all S3 options
- Data stored across multiple Availability Zones
Recommended for:
- long-term data archival accessed once or twice a year
- retaining data for regulatory compliance requirements
Durability: 99.999999999%
S3 Outposts
- Provides object storage on-premises
- A single storage class
- Store data across multiple devices and servers
Recommended for:
- Data that needs to be kept local
- Demanding application performance needs to be
EBS
Elastic Block Store is a storage device (called a volume) that can be attached to (or removed from) your instance
- data persists when instance is not running
- tied to one availability zone
- can only be attached to one instance in the same availability zone
Recommended for:
- quickly accessible data
- running a database on an instance
- long-term data storage
EFS
Elastic File System is a serverless network file system for sharing files
- ONLY supports the Linux file system
- accessible across different Availability Zones in the same Region
- More expensive than EBS
Recommended for:
- main directories for business-critical apps
- lift-and-shift existing enterprise apps
- big data and analytics media processing workflows
- content management and web serving
Storage Gateway
Hybrid storage service.
- connects on-premises and cloud data
- File Gateway: virtual on-premises file server
- Tape Gateway: backup with popular backup software
- Volume Gateway: family of gateways that support block-based volumes
Recommended for:
- moving backups to the cloud
- reducing costs for hybrid cloud storage
- low latency access to data
Backup
Helps you manage data backups across multiple data services
- integrates with resources like EC2, EBS, EFS and more
- create a backup plan that includes frequency and retention
EC2 Instance Store
A local storage that is physically attached to the host computer and cannot be removed.
- storage on disks physically attached to an instance
- storage is temporary since data loss occurs when the EC2 instance is stopped
- Faster with higher I/O speeds
Recommended for:
- temporary storage needs
- data replicated across multiple instances
S3 File Gateway
Allows you to store and access objects in S3 from NFS or SMB file data with local caching
Amazon FSx
Offers fully managed third-party file systems (Windows File Server, Lustre) giving users native compatibility and a feature-rich experience
