Your development team is using an Elastic beanstalk environment.
After a week, the environment was torn down and a new one was created.
When the development team tried to access the data on the older environment, it was not available.
Why is this the case?

The AWS documentation mentions the following.
Elastic Beanstalk applications run on Amazon EC2 instances that have no persistent local storage.
When the Amazon EC2 instances terminate, the local file system is not saved, and new Amazon EC2 instances start with a default file system.
You should design your application to store data in a persistent data source.

http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/concepts.concepts.design.htmlElastic Beanstalk is an AWS service that simplifies the process of deploying and scaling web applications. It enables developers to deploy their applications without worrying about the underlying infrastructure. Elastic Beanstalk uses Amazon Elastic Compute Cloud (EC2) instances to run the application and Elastic Block Store (EBS) volumes to store data.
In this scenario, the development team was using an Elastic Beanstalk environment to run their application. After a week, the environment was torn down and a new one was created. When the development team tried to access the data on the older environment, it was not available.
The reason for this is that the underlying EC2 instances in Elastic Beanstalk environments are created with no persistent local storage. This means that any data stored on the local disk of the EC2 instance is lost when the instance is terminated. In Elastic Beanstalk, the EC2 instances are created from Amazon Machine Images (AMIs) that do not have any local storage attached to them. Instead, they use EBS volumes to store data.
However, it's important to note that Elastic Beanstalk provides an option to store data persistently. You can configure your application to use an external data store like Amazon RDS or DynamoDB. In this case, the data would be available even if the environment is terminated and a new one is created.
In summary, the reason why the development team was not able to access the data on the older environment is that the underlying EC2 instances in Elastic Beanstalk environments are created with no persistent local storage. However, it's possible to store data persistently by configuring your application to use an external data store like Amazon RDS or DynamoDB.
