The document compares security patterns and solutions between Amazon Web Services (AWS) and Microsoft Azure for cloud computing. It discusses six key areas of comparison: 1) compliance and regulatory, 2) identity authentication and authorization, 3) secure development, operation and administration, 4) privacy and confidentiality, 5) secure architecture, and 6) provides examples of specific security solutions offered by each cloud provider for different security patterns within each area.

Data Citizenship
Use AWS location Tags to designate the
location for the data processing
Azure information and location Tag. Azure
FrontDoor Service
Cryptographic Erasure Use AWS KMS Use Azure Key Vault
Shared Responsibility Model
AWS provides different Services to protect
data and systems. AWS is only responsible
for the availability and basic security of the
cloud platform
Azure provides different Services to protect
data and systems. Azure provides is only
responsible for the availability and basic
security of cloud platforms
Compliant Data Transfer AWS Location Tag Azure Location Tag
Data Retention
The Data retention policies can be defined
and executed by AWS (e.g. Lambda)
Azure provides option to define data
retention policy in Database System
Data Lifecycle AWS data lifecycle manager Azure blob storage lifecycle
International Data Remanences Database (e.g. DynamoDB) Database ( e.g. Azure Database backup)
