How to Size an Odoo Server

Properly sizing your Odoo server ensures optimal performance, cost efficiency, and room for growth. Here are the key factors to consider when calculating your server requirements.

Key Factors in Server Selection

  • Concurrent Users: The number of users actively working in Odoo at the same time, typically 10-30% of total users.
  • Module Complexity: Heavy modules like Manufacturing, Accounting, or custom integrations require more resources.
  • Database Size: Larger databases need more RAM for caching and faster storage for queries.
  • Workload Type: Report-heavy or API-intensive workloads need additional CPU and workers.

Cloud vs Dedicated Hosting

Cloud VPS (Recommended)

Best for most Odoo deployments. Offers flexibility to scale resources up or down, pay-as-you-go pricing, and easy provisioning. Ideal for businesses with variable workloads or growth plans.

Dedicated Servers

Consider for large enterprises with 100+ concurrent users, strict compliance requirements, or predictable high-resource needs. Offers guaranteed resources without virtualization overhead.

Multi-Cloud Strategy

OEC.sh supports 14+ cloud providers, allowing you to choose based on regional performance, pricing, or compliance needs without vendor lock-in.

Frequently Asked Questions

Common questions about Odoo server sizing and resource requirements.

How do I calculate Odoo server size?
To calculate Odoo server size, consider your concurrent users (typically 10-30% of total users), number of databases, module complexity, and workload type. Use our calculator above to input these factors and get instant RAM, CPU, and storage recommendations. A general rule is 2GB base RAM plus 150MB per concurrent user, with 2 workers per 10 concurrent users.
What server size do I need for Odoo?
Server size for Odoo depends on your usage: Small deployments (1-20 users) need 4GB RAM, 2 vCPU. Medium deployments (20-50 users) need 8GB RAM, 4 vCPU. Large deployments (50-100 users) need 16GB RAM, 8 vCPU. Enterprise deployments (100+ users) need 32GB+ RAM with separate database servers. Our calculator provides personalized recommendations based on your specific requirements.
How many workers should I configure for Odoo?
Configure Odoo workers using the formula: (2 x CPU cores) + 1 for the base, with approximately 2 workers per 10 concurrent users. Each worker handles one request at a time and uses 150-200MB RAM. For example, 30 concurrent users would need 6-8 workers. Also configure 1-2 cron workers for background jobs. Never exceed 2 workers per CPU core to maintain performance.
What is the best cloud instance for Odoo?
The best cloud instance for Odoo depends on your workload. For small deployments, use AWS t3.medium, DigitalOcean 4GB, or Hetzner CX31. For medium deployments, consider AWS m5.large, DigitalOcean 8GB, or Hetzner CX41. For large deployments, use dedicated instances like AWS m5.xlarge or Hetzner dedicated servers. OEC.sh supports 14+ cloud providers, allowing you to choose based on price, performance, and region requirements.
Should I use shared or dedicated hosting for Odoo?
Use dedicated hosting for production Odoo deployments with consistent performance needs, more than 10 concurrent users, or sensitive business data. Shared hosting can work for development, testing, or very small deployments. Dedicated resources ensure predictable performance without noisy neighbor issues. Cloud VPS instances offer a good balance of cost and dedicated resources for most Odoo deployments.
How do I estimate Odoo resource usage?
Estimate Odoo resource usage by monitoring: RAM usage (base 2GB + 150MB per worker), CPU usage (spikes during reports and heavy operations), database size (starts at 100MB, grows 1-5GB per year depending on transactions), and storage for attachments. Use Odoo's built-in profiler and PostgreSQL monitoring. Start with calculated minimums and scale up based on actual usage patterns.
What are the minimum server requirements for Odoo?
Minimum Odoo server requirements are: 2GB RAM (4GB recommended), 2 vCPU cores, 20GB SSD storage, PostgreSQL 12+, Python 3.8+, and Ubuntu 20.04+ or Debian 11+. For production use, double these minimums. Odoo 17+ requires more resources than older versions. Always include headroom for growth and peak usage periods.
How does database size affect Odoo server requirements?
Larger databases require more RAM for PostgreSQL caching and more CPU for query processing. For databases under 10GB, standard configurations work well. For 10-50GB databases, increase PostgreSQL shared_buffers to 4GB+ and consider SSD storage. For databases over 50GB, use a separate PostgreSQL server with dedicated resources. Monitor slow queries and optimize indexes as your database grows.
