Odoo with high availability on AWS

[EspiritoSantoAlex]

I am implementing Odoo ERP to work with high availability on AWS. I configured the Docker cluster service called ECS, but when I use more than one instance, Odoo seems to lose control of sessions, generating different types of errors and bad behavior.
What should I configure to fix this problem?

P.S. Using just a single instance, Odoo works perfectly.

Odoo stores session files on disk on each instance, so depending on which instance is connected to, the session may or may not be there. A couple ideas:

1. Configure ALB ¹ to use same instance for a given session.
2. Install an Odoo module ² to store sessions in the database instead.
