Hey @Ishaan, follow these steps to configure your Beanstalk's auto-scaling group:
- 
Open the Elastic Beanstalk console.
 
- 
Navigate to the management page for your environment.
 
- 
Choose Configuration.
 
- 
On the Capacity configuration card, choose Modify.
 
- 
In the Auto Scaling Group section, set Min instances to 2.
 
- 
Choose Apply.
 
In step 5, I've mentioned setting min instances to 2. That is to ensure High Availability.
