configuring odoo for high availability on AWS ECS

Question

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.

The sessions are stored as files in /sessions/ so you need a shared storage like AWS EFS to share it between your instances. Or you can use a module to store the sessions on a database, like https://apps.odoo.com/apps/modules/13.0/wk_redis_session but you may still face issues with the filestore, containing PDF etc but also assets bundles that will stay not-shared.
