Data Locality

Customer chooses where to place data

AWS regions are geographically isolated by design

Data is not replicated to other AWS regions and doesn’t move unless you choose to move it

Data Locality in practiceBlock level storage

Instance Storage (Elastic Cloud Compute - EC2)

Elastic Block Storage (EBS)

Object level storageSimple Storage Service (S3)

Database storageRelational Database Service (RDS)

Auditing - Comparisonon-prem vs on AWS

Start with bare concreteFunctionally optional – you can build a secure system without itAudits done by an in-house teamAccountable to yourselfTypically check once a yearWorkload-specific compliance checksMust keep pace and invest in security innovation

on-prem

Start on base of accredited servicesFunctionally necessary – high watermark of requirementsAudits done by third party expertsAccountable to everyoneContinuous monitoringCompliance approach based on all workload scenariosSecurity innovation drives broad compliance

on AWS

What this means

You benefit from an environment built for the most security sensitive organizations

AWS manages 1,800+ security controls so you don’t have to

You get to define the right security controls for your workload sensitivity

You always have full ownership and control of your data
