Self-Hosted vs. Cloud Face Recognition: Pros, Cons, and When to Choose Each

The Deployment Decision

When adopting face recognition, one of the first decisions is where to run it: in the cloud via an API, or self-hosted on your own infrastructure. Each has clear advantages.

Cloud Face Recognition API

A managed service where you send images to an API endpoint and receive results.

Pros:

• No infrastructure to manage

• Instant setup — make API calls in minutes

• Automatic updates and improvements

• Scales automatically with demand

• Lower upfront cost

Cons:

• Data leaves your network

• Dependent on internet connectivity

• Ongoing subscription costs

• Less control over processing

Best for: Startups, SaaS products, mobile apps, teams without ML infrastructure.

Self-Hosted Face Recognition

Run the face recognition engine on your own servers, behind your firewall.

Pros:

• Complete data sovereignty — nothing leaves your network

• Works offline (no internet required)

• Lower per-unit cost at very high volumes

• Full control over the infrastructure

• Compliance with strict data regulations

Cons:

• Requires server infrastructure (GPU/CPU)

• You manage updates and maintenance

• Higher upfront cost

• Need technical expertise to deploy

Best for: Government, healthcare, banking, high-security environments, air-gapped networks.

ARSA Offers Both

ARSA Face Recognition API is unique in offering both deployment models:

• Cloud API at faceapi.arsa.technology — start free, scale with plans

• On-premise SDK — the same technology runs on your hardware

This means you can prototype with the cloud API and migrate to self-hosted when ready, with no code changes.

Decision Framework

| Factor | Choose Cloud | Choose Self-Hosted |

|--------|-------------|-------------------|

| Data sensitivity | Low-medium | High (regulated) |

| Internet availability | Reliable | Unreliable/none |

| Volume | Low-medium | Very high |

| Team expertise | Limited ML ops | Has infra team |

| Time to market | Need it now | Can invest setup time |

| Budget | Predictable monthly | Upfront investment OK |
