I want to terminate some environments from Elastic Beanstalk but when I click on terminate environment the following warning appears:

Terminating this environment will also terminate its associated resources.

* URL - name-environment.eu-west-1.elasticbeanstalk.com will be released.

* Additional resources – any resources associated with this environment will also be terminated.

I want to terminate all the environments inside the app ‘App1’ (Region: Ireland) and I want to keep the environments inside the app ‘App2’.

My question is.. Is there a possibility that some of these resources could also be used by other environments? And if this is possible, would I be able to see what environments are using the same resources before terminating the environment?

I also need to delete the database used by the environments that I have to terminate (database ‘staging’) but I need to keep ‘dev-django-db’ and ‘prod-django-db’ databases because they are the databases used by the environments inside the ‘App2’ app.

I can see that all of them share the same VPC and that is why I’m wondering if when I delete the staging database that could affect in any way to the other two databases.

The VPC is likely the default VPC for that AWS account and shouldn't be affected by deleting an Elastic Beanstalk app.

If you are intending on keeping any data beyond a short-lived experiment (and certainly in production), it's a good idea to create your RDS databases independently from your Elastic Beanstalk resources. This will ensure that your data isn't tied to the lifecycle of an app/environment. This might mean additional creating/exporting/saving/importing/configuring of database users/credentials for your Django app but will be worth it to save the worry about accidentally deleting a database!

Relevant documentation.

Thanks Blair,

In my case the databases that I'm using for the Django Elastic Beanstalk environments were created outside Elastic Beanstalk then I connected with the environments using inbound rules.

So I guess that if the 'staging' database is removed it should affect the new databases even if they share the default VPC.

What I don't understand very well is how the EC2 instances work and if there is a chance that terminating an environment could eliminate instances that are used in the DB.
