- 1Simple Storage Service (S3)provides developers and IT teams with secure, durable,
highly-scalable object storage. Amazon S3 is easy to use, with a simple web services interface to store and retrieve any amount of data from anywhere on the web. - 2S3 Storage Tiers (5)Standard
Infrequently Accessed
One Zone Infrequently Accessed
Reduced Redundancy Storage
Glacier - 3S3 Intelligent Tieringoptimize storage costs automatically when data access patterns change, without performance impact or operational overhead
- 4S3 Standard Tiering99.99% availability
99.9999...% durability (eleven 9s)
stored redundantly across multiple devices in multiple facilities and is designed to sustain the loss of 2 facilities concurrently - 5S3 - IA (Infrequently Accessed)For data that is accessed less frequently, but requires rapid access when needed lower fee than S3, but you are charged a retrieval fee
- 6S3 - One Zone IASame as S3 - IA however data is stored in a single availability zone only, still same durability but only 99.5% availability. Cost is 20% less than S3 - IA
- 7Reduced Redundancy StorageDesigned to provide 99.99% durability
99.99% availability of objects over a year
Used for data that can be recreated if lost - 8Glaciervery cheap but used for archival only
Optimized for data that is infrequently accessed and it takes 3-5 hours to restore from Glacier - 9If the file is to be encrypted at upload time, what parameter will be included in the request headerx-amz-server-side-encryption
- 10x-amz-server-side-encryption Encryption Methods (2)AES256
aws:kms - 11Types of Workloads (2)GET-Intensive
Mixed Request Type - 12GET-Intensive Workloaduses CloudFront content delivery service to get the best performance. CloudFront will cache your most frequently accessed objects and will reduce latency for your GET requests
- 13Mixed Request Type WorkloadA mix of GET, PUT, DELETE, or GET Bucket
The key names you use for your objects cam impact performance for intensive workloads - 14Encryption at rest Server Side EncryptionSSE-S3

SSE-C - 15Edge LocationThis is the location where content will be cached. This is separate to an AWS Region/AZ
- 16OriginThe is the where all the files that the CDN will distribute.
can be an S3 bucket, EC2 instance, an ELB or Route53 - 17Distribution (2)The name given the CDN, which consists of a collection of Edge location
