MelanieKraintz007 explores Azure Red Hat OpenShift’s new Confidential Containers, detailing how this general availability release advances cloud security and zero-trust for confidential workloads on Azure.

Confidential Containers Now Available on Azure Red Hat OpenShift (ARO)

Announced at Microsoft Ignite 2025 in San Francisco, Microsoft and Red Hat have launched Confidential Containers for Azure Red Hat OpenShift (ARO), delivering hardware-based data protection to containerized workloads in the public cloud.

What are Confidential Containers on ARO?

Confidential Containers on ARO combine Azure’s Confidential Computing features with Red Hat OpenShift, letting organizations encrypt data in use, at rest, and in transit. Sensitive workloads run inside Trusted Execution Environments (TEEs) built on AMD SEV-SNP or Intel TDX, ensuring hardware-level isolation and workload integrity via attestation (zero-trust).

Technical Highlights

  • Rollout Timing: Available in major Azure regions following Ignite 2025
  • OpenShift Version: Supported with ARO 4.15 and later
  • Hardware Support: AMD SEV-SNP, Intel TDX for CVMs (Confidential Virtual Machines)
  • Peer Pod Architecture: Each container isolated from host and other cluster workloads
  • Workload Attestation: Verifies code and data integrity before execution
  • Security Consistency: Uniform zero-trust across cloud, hybrid, and on-premises deployments
  • Compatible Workloads: Confidential and standard containers run side-by-side; supports existing CI/CD processes

Benefits for Organizations

Category Value
Security Hardware isolation and attestation prevent privileged access
Compliance Meets mandates (HIPAA, GDPR) for sensitive data
Hybrid Consistency Consistent security model on-prem, hybrid, and cloud
Performance Optimized Confidential VMs reduce overhead
Simplicity Easy enablement from OpenShift console
Workload Integrity Attestations confirm trusted execution

Designed Use Cases

  1. Regulatory Compliance: Process confidential data under privacy mandates
  2. Secure DevOps Environments: Isolate dev/test/prod with enclave security
  3. Confidential Analytics: Analyze regulated/proprietary data

Getting Started & Resources
