Fault-Tolerant
Ready to have redundant resources ready to take over completely
Highly Available
Some degredation is acceptable in order to be highly available
S3 Storage Classes
Standard, Standard Infrequent Access, Onezone Infrequent Access, Glacier
S3 Standard Storage
Performance sensitive use cases, millisecond access
S3 Standard Infrequent Access Storage
Millisecond access, charges retrieval fee so more expensive than standard for frequently accessed data. Can be deployed across multiple availability zones, minimum 30 days storage, 128 KB minimum size fee
S3 One Zone Infrequent Access Storage
Millisecond access, charges retrieval fee so more expensive than standard for frequently accessed data. Only deployed in one availability zone, minimun 30 days storage, 128 KB minimum size fee
S3 Glacier Storage
Minute access, cheaper, mainly for backups, 90 days minimum storage
What is the Max Throughput of the General Purpose SSD EBS storage type
250 MiB/s
What is the Max Throughput of the Provisioned IOPS SSD EBS storage type
500 MiB/s normally and 1,000 MiB/s on nitro based instances
What is the Max Throughput of the Throughput Optimized HDD EBS storage type
500 MiB/s
What is the Max Throughput of the Cold HDD EBS storage type
250 MiB/s
What is the minimum day storage for S3 Standard-IA and S3 OneZone-IA
30 days - you will be charged for 30 days even if you only use it for 1 day.
What is the minimum day storage for S3 Glacier
90 days - you will be charged for 90 days even if you only use it for 1 day.
What is the minimum size fee for S3 Standard-IA and S3 OneZone-IA
