Storage Need and AWS Service Solution
Immediate Access - S3
File System - Amazon EFS
Structured Data with Query - DynamoDB, RDS, CloudSearch 
Rapidly Changing Data - EBS, EFS, DynamoDB, RDS, EC2
Archival Data - Amazon Glacier
Dynamic Website Hosting - EC2, EFS
Temporary Storage - EC2 Local instance store

S3 Notes:
> 0-5TB of Data
3 Storage classes:
  S3 Standard - general purpose frequently accessed
  S3 Standard-Infrequent Access (IA) for long lived, but less frequently accessed
  Glacier - low cost archival data

Glacier Notes:
> 40 TB limit
> Highly secure, druable and flexible storage for archive and backup
> When pulling on archives - you initiate a job to pull the archive
> Using lifecycle policies you can seamlessly move between Glacier and S3 using S3 Data policies
> Can use range retrievals to managed bandwidth costs or targeted part of the archive
> Data can be put into locked 'vaults' for regulatory compliance 
> Take 3-5 hours to pull on data

EFS Notes:
Simple, scalable, elastic highly available and highly durable NFS as a service to EC2 instances.
> Allows for usage across multiple instances
> Good for multi threaded applications with concurrent access to data from multiple EC2s
> Two different modes; Gneral purpose, if over 7,000 file operations a second use Max I/O performance mode.
> EFS is optimized to burst at hight throughput levels for short periods of time
> If using a high number of parallel EC2 - EFS is good. 
> No need to provision in advance
