Built on custom Nitro hardware, they offer strong security guarantees with CPU and memory isolation, comprehensive compliance certifications, and seamless connectivity to AWS services.
Key Advantages
Where AWS Nitro Stops, Phala Keeps Going
Beyond CPU-Only Computing
AWS Nitro Enclaves are limited to CPU workloads. Phala extends confidential computing to GPU TEE with H100/H200 support, enabling private AI inference and training at enterprise scale.
Open-Source Transparency
While AWS uses proprietary Nitro hardware and closed-source attestation, Phala provides fully auditable open-source infrastructure. Every component can be verified and deployed independently.
Multi-Cloud Freedom
AWS locks you into their ecosystem with Nitro-specific implementations. Phala runs anywhere - on-premises, AWS, GCP, or Azure - using standard TEE technologies like Intel TDX and AMD SEV.
Decentralized Key Management
AWS controls your keys through centralized KMS. Phala uses blockchain-secured governance where key management decisions are transparent and community-controlled, not controlled by a single company.
When to Choose Each Solution
Choose AWS Nitro Enclaves if you're already deep in the AWS ecosystem, need immediate enterprise support, and your confidential workloads are CPU-only with no AI/GPU requirements.
Choose Phala Cloud if you need GPU TEE support for AI workloads, want infrastructure sovereignty without vendor lock-in, or require full transparency through open-source auditability.
AWS Nitro requires significant AWS expertise and ties you to their proprietary platform, while Phala offers standard container deployment across any infrastructure.
Consider long-term flexibility: AWS creates dependency on their ecosystem, while Phala enables true multi-cloud portability and infrastructure control.
