Odoo Server Requirements

Odoo requires its own system to work efficiently, a standalone VPS or PC with Ubuntu OS optimized for good performance with the right memory and CPU power. This depends on the number of users and the expected load they do on the system. 

You need to assign the no. of workers(Thread) in odoo configuration file. One worker can handle around 6 concurrent users. 

Configuration sample

• Server with 4 CPU, 8 Thread

• 60 concurrent users

• 60 users / 6 = 10 <- theoretical number of worker needed

• (4 * 2) + 1 = 9 <- theoretical maximal number of worker

• We'll use 8 workers + 1 for corn. We'll also use a monitoring system to measure CPU load and check if it's between 7 and 7.5.

• AM = 9 * ((0.8*150) + (0.2*1024)) ~= 3Go RAM for Odoo

Conclusion :

You will need approx 4 GB Ram dedicated for odoo, 4 CPU If you add 4+ will be an advantage on the speed performance.

Hard disk, 100 GB will be enough, but it depends if you are taking database backup every day in the same instance. then hard disk size cannot be predicted, but if you are taking database regularly and clearly it regularly only keeping last month or last week database backup then you won't need more hard disk size.

Odoo Server Architecture

As a client-server web-based application odoo can be hosted in several ways based on the requirements. The goal is to utilize the hardware or virtual servers to achieve the high performance needed.
