Hello!


I'm researching Odoo Enterprise and I'm looking for some guidance on the hardware requirements. I know there's a lot of YMMV (Your Mileage May Vary) in this question but I'm really just looking for a ballpark estimation on the hardware to run a high quality deployment.


I plan to run it in Azure with one or more Linux VMs (to save costs on Windows licensing). We will have about 25 users, using various apps. Here's the apps I plan to use from the outset.


Heavy usage:

  • CRM

  • Invoicing

  • Sales

  • Sales

  • Accounting

  • Inventory

  • Manufacturing

  • Purchase

Light usage:

  • Documents

  • Maintenance

  • Quality

  • Marketing Automation

  • Easypost integration


How many VMs should I plan to deploy and which role(s) would they each hold? And for each VM what should I plan to allocate for CPU, memory, and initial storage?


Thank you!

With 25 Users we would recommend a single VM with multiple cores - probably 1 or 2.

A worker consumes a CPU.

See https://www.odoo.com/documentation/14.0/setup/deploy.html#builtin-server

As a rule of thumb, you should count about 1 worker per 25 users or 5000 daily visitors. It can vary much depending on the database usage and website.

1 worker is about 6 concurrent users.

CONCURRENT means "at the same time" so for Odoo, this would be 6 users ALL clicking a button at the exact same time.  Remember 99% of the time users are probably reading or typing (not clicking buttons) and that doesn't count as 'using' Odoo.  Only when you click a button, running a report, importing data, etc.

Without knowing what these your users would do, 6 concurrent is normally equated to 25 users.

A very rough rule would be 1 worker per 25 regular users. 

If those users log in once a day to submit their timesheet, they would be considered LIGHT users.  If those users enter Sales Orders all day long, one call after the other without a break, they would be considered HEAVY users. 

For some Customers 1 worker could support 50 users. 

It really depends on how much time each User spends in Odoo and what they do when they are there.

Thanks for the info and link. I see it mentions memory too.

What about storage? Any guidance there? I suspect that is also minimal unless Odoo does a lot of logging. We're currently Microsoft NAV users and the database is huge because of the logging I have turned on.

Side note... does/can Odoo log all user activity? Can I answer the question, "Who changed the price of this item and when?"

Storage is what you need for the database (master data plus transactions) as well as attachments (uploads). How many Products? Customers? Vendors? Orders? Transfers? Invoices? Payments? Notes? per User per Day? There is default logging of many fields and you can customize Odoo to log more and/or leverage third party modules for audit logging. I would recommend you start with Odoo.sh, which you can do monthly, as we give you access to not only the shell of the VM but statistics on usage you can leverage to scale up when you self-host. It starts at $73 a month - see https://www.odoo.sh/pricing
