Frequently Asked Questions

Common questions about Lambda compute platform.


General

What is Lambda?

Lambda is a privacy-focused compute renting platform. Unlike traditional cloud providers (AWS, Google Cloud, Azure), Lambda ensures your data, logs, and processes remain completely private—even from us.

Key Differentiator: Zero-knowledge architecture means we can't access your data even if we wanted to.

How is Lambda different from AWS/Google Cloud/Azure?

FeatureLambdaTraditional Clouds
Provider Access to Logs✗ None✓ Full access
Provider Access to Data✗ Encrypted with your keys✓ Can access
Memory Privacy✓ Hardware-encrypted (SGX/SEV)✗ Visible to hypervisor
Zero-Knowledge✓ Yes✗ No
Egress Fees✗ Free✓ Expensive ($0.09/GB)

Who should use Lambda?

  • Healthcare orgs handling HIPAA data
  • Financial services with sensitive transactions
  • Legal firms needing client confidentiality
  • Researchers with proprietary datasets
  • Privacy-conscious developers
  • Anyone who values data sovereignty

What can I run on Lambda?

Virtually anything that runs on Linux:

  • Web applications & APIs
  • Databases (PostgreSQL, MySQL, MongoDB, Redis)
  • Machine learning workloads
  • Batch processing & ETL
  • Game servers
  • CI/CD pipelines
  • Custom applications

Privacy & Security

Can Lambda access my data?

No. Our architecture makes this impossible:

  1. Client-side encryption: You encrypt data before upload
  2. Hardware isolation: Secure enclaves (SGX/SEV) prevent hypervisor access
  3. No keys on platform: Your encryption keys never leave your control
  4. Blind orchestration: We manage infrastructure blind to contents

What if Lambda gets hacked?

Even if our control plane is compromised:

  • Attackers cannot decrypt your data (no keys)
  • Cannot access instance memory (hardware encryption)
  • Cannot read storage (encrypted with your keys)
  • Cannot inspect network traffic (end-to-end encryption)

How do I verify my instance is secure?

Use remote attestation:

lambda attest inst_abc123 --output proof.json
lambda verify proof.json

This cryptographically proves your workload runs in a genuine secure enclave.

Can you help debug my application?

Not by default (we can't see your logs). But you can grant temporary, scoped access:

lambda support grant-access inst_abc123 \
  --duration 24h \
  --scope "logs:read" \
  --reason "Debugging memory leak"

This creates an auditable access log.

What happens to my data if I delete my account?

All instances and volumes are destroyed immediately. Data is securely erased (DoD 5220.22-M standard). Backups are deleted within 24 hours.

Do you comply with GDPR/HIPAA?

Yes. Lambda is:

  • ✓ SOC 2 Type II certified
  • ✓ HIPAA compliant (BAA available)
  • ✓ GDPR compliant
  • ✓ ISO 27001 certified
  • ✓ PCI DSS Level 1

See Compliance Documentation →


Pricing & Billing

How much does Lambda cost?

Starting at $0.05/hour ($36/month) for compute-1x instances.

Free Tier: 750 hours/month of compute-1x (runs 1 instance 24/7 free).

See Pricing →

Do you charge for data transfer?

No. Unlike other clouds:

  • ✗ No inbound fees
  • ✗ No outbound fees
  • ✗ No inter-instance fees
  • ✗ No cross-region fees

All data transfer is free.

What's the "privacy premium"?

Lambda costs ~$100-150/month more than traditional clouds for equivalent compute. This pays for:

  • Hardware secure enclaves
  • Blind orchestration infrastructure
  • Enhanced security auditing
  • Zero-knowledge architecture

For many use cases, this is offset by free egress.

Can I get a refund?

Prorated refunds within 7 days of instance creation. Running time is non-refundable. Unused committed hours don't roll over.

Do you offer discounts?

Yes:

  • Committed Use: Up to 40% discount for 12-month commitments
  • Volume: 10-20% for $10K+/month usage
  • Academic/Nonprofit: 50% discount with verification
  • Startups: Apply for startup credits

Technical

What regions are available?

8 regions globally:

  • US: us-west-1 (California), us-east-1 (Virginia)
  • EU: eu-west-1 (Ireland), eu-central-1 (Frankfurt)
  • Asia: ap-southeast-1 (Singapore), ap-northeast-1 (Tokyo), ap-south-1 (Mumbai)
  • South America: sa-east-1 (São Paulo)

What operating systems can I use?

  • Debian (10, 11, 12)
  • CentOS Stream (8, 9)
  • Rocky Linux (8, 9)
  • Fedora (38, 39)
  • Arch Linux
  • Custom images (bring your own)

Can I use Docker?

Yes! Docker works perfectly:

# Install Docker
sudo apt update && sudo apt install docker.io

# Run containers
docker run -d nginx

Kubernetes also supported.

How do I SSH into my instance?

# Using Lambda CLI (easiest)
lambda ssh inst_abc123

# Or standard SSH
ssh lambda@203.0.113.42

# With specific key
ssh -i ~/.ssh/my-key lambda@203.0.113.42

Can I get a static IP?

Yes. All instances get static IPs by default. They don't change unless you release them.

How do I resize an instance?

lambda resize inst_abc123 --type compute-8x

Causes ~30 seconds of downtime during resize.

Can I attach multiple volumes?

Yes. No limit on volumes per instance:

lambda create volume --name data1 --size 100GB
lambda create volume --name data2 --size 500GB
lambda attach volume vol_abc123 --instance inst_xyz789
lambda attach volume vol_def456 --instance inst_xyz789

What's the maximum instance size?

  • CPU: 32 vCPU (compute-32x)
  • RAM: 256 GB (memory-32x)
  • Storage: 4 TB (storage-16x)
  • GPU: 4x H100 80GB (gpu-h100-4x)

Need larger? Contact sales@lambda.io for custom configurations.


Performance

How fast are Lambda instances?

On par with major clouds:

MetricLambdaAWS EC2
CPU Performance100%100%
Storage IOPS40K+40K+
Network Bandwidth10 Gbps10 Gbps
Encryption Overhead~5%N/A

Privacy adds minimal overhead.

Is there any performance impact from encryption?

Minimal:

  • Storage: ~5% overhead (hardware-accelerated AES)
  • Network: ~2ms latency (TLS overhead)
  • CPU: <1% (SEV/SGX overhead)

For most workloads, this is negligible.

What's the SLA?

  • Uptime: 99.95% (4.35 hours downtime/year)
  • Network: 99.9%
  • Support Response: Varies by plan

Enterprise customers can get custom SLAs up to 99.99%.


Backup & Recovery

How do backups work?

Take snapshots:

# Manual snapshot
lambda snapshot create inst_abc123 --name "before-deploy"

# Scheduled snapshots
lambda snapshot schedule inst_abc123 --frequency daily --retain 7

Snapshots are encrypted with your keys.

Can I restore to a different region?

Yes:

# Copy snapshot to different region
lambda snapshot copy snap_abc123 --to-region eu-west-1

# Restore in new region
lambda create instance \
  --from-snapshot snap_abc123 \
  --region eu-west-1

What if I lose my encryption keys?

Your data is unrecoverable without keys. This is by design—neither you nor Lambda can decrypt without the key.

Best Practices:

  • Store keys in encrypted vault (1Password, Bitwarden)
  • Keep offline backup in secure location
  • Consider key escrow for organizations

Account & Billing

How do I delete my account?

To delete your account:

  1. Go to Dashboard → Settings → Account
  2. Scroll to "Delete Account" section
  3. Review what will be deleted
  4. Click "Delete My Account" and confirm

Alternative: Use the CLI:

lambda account delete --confirm

Or contact support@lambda.io for assistance. All data is permanently deleted within 24 hours.

Can I transfer ownership of instances?

Not directly. You can:

  1. Take snapshot
  2. Share snapshot with another account
  3. Other account restores from snapshot
lambda snapshot share snap_abc123 --with-account acct_xyz789

Do you offer enterprise agreements?

Yes. For $10K+/month commitments, we offer:

  • Custom pricing
  • Volume discounts
  • Dedicated support
  • Custom SLAs
  • On-premise deployment options

Contact sales@lambda.io


Troubleshooting

Can't connect via SSH

  1. Check instance status: lambda status inst_abc123
  2. Verify firewall: lambda firewall list inst_abc123
  3. Check SSH key: lambda ssh-keys list
  4. Try different key: ssh -i ~/.ssh/other-key lambda@ip

Instance won't start

  • Check quotas: lambda quotas
  • Verify billing: lambda billing status
  • Try different region
  • Check status page: https://status.lambda.io

High CPU/memory usage

# Check metrics
lambda metrics inst_abc123

# SSH in and investigate
lambda ssh inst_abc123

Lost encryption key

If you lose your encryption key, data is unrecoverable. This is a feature, not a bug—it ensures even we can't access your data.

Prevention: Store keys securely and maintain backups.


Migration

How do I migrate from AWS?

  1. Export data from AWS
  2. Create Lambda instance
  3. Transfer data (scp, rsync, or upload)
  4. Test thoroughly
  5. Switch traffic
  6. Terminate AWS resources

See Migration Guide →

Can I run Lambda and AWS in parallel?

Yes. Use Lambda for sensitive workloads, AWS for others:

AWS: Public-facing services

Lambda: Backend with sensitive data
