AWS Data Storage Options

Economist often deal with large and complicated data.  However, the degree to which data is expanding in business, academia, and government in many instances has outpaced the storage and computing capacity of individual personal computers, powerful as they may be. Therefore economists must continue to evolve and adapt to new technologies for storing and modeling ever more expansive data. One such technology is Amazon Web Services(AWS).

The goal of this post is to describe how to create new data storage capabilities by using Amazon Web Services. The first step is to set up and create a new AWS account, next explore the different storage options below.

Elastic Block Storage (EBS)

How is it used?

EBS is a volume-based storage that isn’t associated with any particular instance; rather, it’s attached to instances to provided additional storage. It can be attached for that instance but is detached from the instance when it terminates

To summarize:

S3, thigh highly scalable object

EBS, the volume storage offering

DynamoDB, the highly scalable key-value service

Glacier, the inexpensive and highly durable archiving service

Guidelines when choosing among AWS storage services:

  1. Become knowledgeable about all services
  2. Leverage the strengths of the services so Amazon does the heavy lifting so you don’t have to
  3. Choose services that are appropriate and necessary
  4. Use what-if approaches to make service choices (e.g. what is our users grow by 10 times)
