## What does Phala Cloud do?

Phala Cloud is a decentralized confidential computing platform that enables developers to deploy AI applications with full privacy guarantees. Built on open-source technology, it provides GPU TEE support for confidential AI workloads, blockchain-secured key management, and multi-cloud deployment flexibility without vendor lock-in.

## What are AWS Nitro Enclaves?

AWS Nitro Enclaves are Amazon's enterprise solution for confidential computing, providing hardware-isolated compute environments within EC2 instances. 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

1. 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.

2. 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.

3. AWS Nitro requires significant AWS expertise and ties you to their proprietary platform, while Phala offers standard container deployment across any infrastructure.

4. Consider long-term flexibility: AWS creates dependency on their ecosystem, while Phala enables true multi-cloud portability and infrastructure control.
