Fictional case study

AWS security architecture case study

April 2026.

A fictional case study for Rossco's Coffee, covering security architecture and migration planning on AWS.

The plan starts from an evaluation of the current environment and a vulnerability and risk assessment, then sets out the target architecture, how to test and migrate to it, and how to run it afterwards.

What it covers

  • Evaluation of the current cloud architecture, access control and security controls
  • Cloud and service models, security and sovereignty, and designs for high demand and infrastructure failure
  • Access control, data storage and encryption, classification, network segmentation, and privilege, authentication and authorisation
  • Testing environments, QA, disaster recovery, blue-green deployment and the migration strategy
  • Log scrubbing, remote log monitoring, maintenance and lifecycle management
  • A cloud incident response plan with disaster recovery and reporting

A 36-page planning case study. The architecture is proposed rather than presented as a live production system, and AWS services and guidance change often.
