Today, Amazon EC2 announces an enhancement to Replace Root Volume to enable customers to easily patch or upgrade their software. The feature now supports the replacement of the root volume using an updated AMI without stopping the instance. This allows customers to update their applications and guest operating system, while retaining the instance store data, networking and IAM configuration.

Customers can use the feature to patch their software quickly without having to incur the operational costs of instance store data backups or replication. Customers with stateful workloads can use the feature to ensure that their software is up-to-date and improve their security posture by patching more frequently.
