Multi Laravel Instances with One common database

Hey guys,

We have already built a nice Laravel instance and plan to create 2 new instances. The goal is to build a kind of environment with one feature by instance (and by url)

Exemple : Instance 1 (we already have) : https://instance1.com (let users build a website) Instance 2 : https://instance2.com (let users handle orders and payments) Instance 3 : https://instance3.com (let users access to a backend if he payed)

We want to make it great for the users : If one user is logged to an instance, he is automatically logged on the others.

From now, we think to do like this :

• One common database for all the instances
• The table users is "shared"
• Other tables are specific for each instance (maybe with a prefix in the table, like : instance1_table, instance2_table)

Questions :

• Is it the good way to do this in Laravel ?
• How can we manage to let the user session shared between instance ( same APP_KEY, and it's gonna work directly ) ?
• How to be sure to don't put the mess at every migrations ?

Thanks a lot

Jo
