The Elastic Beanstalk deployment types include: All at Once, Rolling, Rolling with Additional Batch, Immutable, and Traffic Splitting.
What is the All at Once deployment type?
The All at Once deployment type involves a service interruption where everything goes down. Rolling back requires a further All at Once Update.
What is the Rolling deployment type?
The Rolling deployment type involves reduced capacity during deployment. Rolling back requires a further rolling update.
What is the Rolling with Additional Batch deployment type?
The Rolling with Additional Batch deployment type maintains full capacity. Rolling back requires a further Rolling Update.
What is the Immutable deployment type?
The Immutable deployment type maintains full capacity. To roll back, delete the new instances. It is the preferred option for mission-critical production systems.

What are the two options for deploying RDS when working with Elastic Beanstalk?
The two options for deploying RDS when working with Elastic Beanstalk are: inside Beanstalk and outside Beanstalk.
What is the inside Beanstalk option for deploying RDS?
Inside Beanstalk, it is quick and easy to add a database. However, the database is also terminated when you terminate the Elastic Beanstalk stack. This option is suitable for development and testing only.
What is the outside Beanstalk option for deploying RDS?
Outside Beanstalk, deleting the stack doesn’t impact the database. Additional configuration is required, such as security group and connection information. This option is suitable for production environments and offers more flexibility.
