Testing AWS Managed Microsoft AD Resilience using AWS Fault Injection Service
Microsoft Workloads on AWS Blog
This article discusses how to test the resilience of AWS Managed Microsoft AD using AWS Fault Injection Service (FIS), a tool for conducting controlled chaos engineering experiments.
- AWS Managed Microsoft AD operates domain controllers across two Availability Zones, managed by AWS
- FIS provides three methods for testing network connectivity disruption: All, Availability-Zone, and Prefix-List
- Comprehensive observability is crucial, including CloudWatch metrics, network traffic monitoring, and Windows Event logging
- Testing should start in development environments with a progressive approach
- The test involves creating an FIS experiment template to disrupt connectivity to a specific domain controller
The goal is to validate application behavior during Active Directory service disruptions, helping organizations improve their disaster recovery and resilience strategies.
