- Geo-Replication & Private Link - Workload Identity (OIDC) - Declarative Domain-Specific DSL
- ACR Tasks Base Image Patching - Actions Runner Controller(ARC)- actionOnUnmanage Auto-Purge
- Cosign & Defender Scanning - Azure Pipelines Multi-Stage - denySettingsMode Anti-Drift
| Capability | Azure Solution | AWS Equivalent | GCP Equivalent | Key Cloud Native Differentiator |
|---|
| Container Registry | Azure Container Registry (ACR) | Amazon ECR | Artifact Registry | Geo-replication replicates images across regions with a single unified FQDN; ACR Tasks automates base OS patching. |
| CI/CD Automation | Azure DevOps & GitHub Actions | AWS CodePipeline / CodeBuild | Cloud Build & Cloud Deploy | Keyless OIDC federation eliminates stored secrets; Actions Runner Controller (ARC) runs ephemeral pods on AKS. |
| Infrastructure as Code | Azure Bicep | AWS CDK / CloudFormation | Google Cloud Deploy / Config Connector | Zero-day support for all Azure resource providers without waiting for third-party engine updates. |
| Lifecycle & Anti-Drift | Azure Deployment Stacks | CloudFormation Drift Detection | Terraform State Locking | Natively purges deleted resources (actionOnUnmanage: delete) and blocks console tampering via deny-assignments. |
