On-Premises vs. Cloud Hosting for LLMs Like DeepSeek-R1: A Detailed Comparison

Want to host Deepseek-r1 for inference but are unsure whether to run it on a local server (on-premises) or a cloud server (AWS, GCP, Azure). Each approach has pros and cons depending on cost, latency, security and scalability.

Comparing the benefits of local vs. cloud hosting across key factors like performance, cost, security, control and scalability.

Benefits:

• Lower Operational Costs (After Setup): No recurring cloud fees after initial hardware investment.
• Full Control: Self management of all configurations, updates and optimizations.
• Data Privacy & Security: No external exposure, great for sensitive workloads.
• Low-Latency Inference: No network lag since everything runs locally.
• Custom Hardware Choices: Optimize RAM, GPU, CPU based on workload.

Challenges:

• High Upfront Cost: Expensive hardware purchase (GPUs, power, cooling).
• Limited Scalability: Adding more compute power requires physical upgrades.
• Manual Maintenance: Hardware failures and software updates are your responsibility.
• Power & Cooling Costs: Running AI workloads demands constant power & cooling.

Benefits:

• Scalability on Demand: Increase/decrease resources dynamically.
• Lower Initial Cost: Pay as you go pricing eliminates large upfront investments.
• Managed Infrastructure: Cloud providers handle maintenance, security and availability.
• Global Accessibility: Deploy once, access from anywhere.
• High-Performance GPUs Available: Use A100, H100 or TPU instances instantly.

Challenges:

• Recurring Costs: Usage based pricing can become expensive over time.
• Latency (Network Delays): Dependent on internet speed and cloud region.
• Vendor Lock-in: Harder to migrate if heavily integrated with a single cloud provider.
• Data Privacy Risks: Sensitive data stored offsite may have compliance issues.

Cost Efficiency

• Local Server: After initial investment
• Cloud Server: Flexible pay-as-you-go pricing

Performance

• Local Server: No network latency
• Cloud Server: High-performance GPU access

Scalability

• Local Server: Limited physical scaling
• Cloud Server: Instantly add/remove resources

Security

• Local Server: Complete data privacy
• Cloud Server: Data stored in external cloud

Maintenance

• Local Server: Manual updates & repairs
• Cloud Server: Managed infrastructure

Deployment Time

• Local Server: Slow setup (hardware purchase)
• Cloud Server: Immediate instance availability

Custom Hardware

• Local Server: Fully customizable
• Cloud Server: Limited to cloud instance types

• Choose a Local Server if:

• Need of low latency inference with no network dependency.

• The project requires high data privacy (e.g., confidential research).

• Want long-term cost savings by avoiding cloud fees.

• Already have a dedicated IT team to manage hardware & maintenance  

• Choose a Cloud Server if:

• Need on demand scalability for fluctuating workloads.

• Want a fast setup with no upfront hardware purchase.

• Prefer managed infrastructure with security updates.

• Don’t mind paying for cloud usage in exchange for flexibility.

Both local and cloud hosting have advantages.

• If priority is control, privacy and predictable costs then local hosting is best.
• If priority is scalability, fast deployment and managed services then cloud hosting is the better option.
