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 GCP Confidential VMs?

Google Cloud Confidential VMs use AMD SEV and Intel TDX to encrypt VM memory during processing. GCP excels at enterprise features with seamless lift-and-shift migration, comprehensive compliance certifications, and deep integration with Google's ecosystem including BigQuery, Cloud Run, and Vertex AI.

Key Advantages

GPU TEE for Confidential AI

GCP Confidential VMs only protect CPU workloads. Their A3 GPU instances lack TEE protection, exposing AI models and data. Phala provides true GPU TEE with H100/H200, keeping your AI workloads confidential end-to-end.

Break Free from Google Lock-in

GCP ties you to Google's ecosystem with proprietary APIs and services. Phala uses standard TEE technologies, enabling deployment on any cloud or on-premises infrastructure without vendor dependency.

Transparent vs Black Box

Google's confidential computing relies on proprietary systems you cannot audit. Phala is fully open-source, allowing you to verify every component and process for true security transparency.

Decentralized Trust Model

GCP requires trusting Google as a centralized authority. Phala uses blockchain-secured attestation and key management, removing single points of control and enabling community-governed trust.

When to Choose Each Solution

Choose GCP Confidential VMs if you're already committed to Google Cloud, need easy lift-and-shift VM migration, and your workloads are CPU-only without AI/GPU requirements.
Choose Phala Cloud if you need confidential AI with GPU TEE support, want multi-cloud flexibility, or require infrastructure sovereignty with open-source transparency.
GCP offers convenient integration with Google services but creates vendor lock-in, while Phala requires containerization but provides true portability.
Consider control vs convenience: GCP manages everything but limits your options, while Phala gives you full control over your confidential computing infrastructure.

Pricing Comparison

Phala Cloud

Transparent pay-what-you-use pricing starting from $0.10/hour for CPU TEE and $0.50/hour for GPU TEE. No enterprise markup, hidden fees, or long-term commitments required.

GCP Confidential VMs

Premium GCP pricing with enterprise SLAs, Confidential VM surcharges on top of standard Compute Engine costs. Often requires committed use discounts for cost optimization.
