SAA

Here's a quick cheat-sheet to remember all these services:

EMR (Elastic Map Reduce): Big Data / Hadoop / Spark clusters on AWS, deployed on EC2 for you

Glue: ETL (Extract Transform Load) service on AWS

OpsWorks: managed Chef & Puppet on AWS

ElasticTranscoder: managed media (video, music) converter service into various optimized formats

Organizations: hierarchy and centralized management of multiple AWS accounts

Workspaces: Virtual Desktop on Demand in the Cloud. Replaces traditional on-premise VDI infrastructure

• Update multiple account and regions with a signle operation

• Max execution time of 1 year
• human approval feature

• Hadoop
• Map Reduce for big data

• Chef & Puppet

• Covert media files

• Virtual Desktop Infrastructure
• VDI
• Cloud Desktop

• ETL
• Catelog

• Chef Service

• Create various accounts ... separate their dev, test...

• NOT: "Edit EC2 instance rle to add permissions to S3":  This would allow the first app to access S3 as well, which is a security risk.

SAP

• Steop functions does not integrate natively with AWS Mechanical Turk, SWF does
• Activity task, you need to install activity worker to poll the step functions

• Handle recesive tasks
• AWS Mechanical Turk

• EMR within a VPC available only single AZ
• For high speed, use EBS for temporary storage
• For Permanent storage use S3
• Hive intgrate with DynamoDB 

• Core Node: run task and store data
• Task Node: just run task
