7 How can I control cost?

Answer: You are responsible for operating your AWS account and paying for the hosting costs. A great way to minimize costs is to stop your instance when you are not using it. Starting your instance just takes a few minutes, so you can fire it up when you need it. To stop your instance, go to AWS EC2 console, right click the instance and choose “Stop” from the context menu. To start it again, choose “Start” from the same context menu.

Please note that even after stopping the EC2 instance, there are a few items that can still incur costs, such as EBS volumes. If you wish to stop using your HANA One instance, and do not want to pay related monthly bills, you will need to terminate your instance.

To terminate your instance, choose “Terminate” from your context menu. Once the instance is terminated, by default, only the root volume is deleted; other EBS volumes attached to the instance are not deleted automatically. If you wish to terminate your instance and no longer need your data, you may delete detached EBS volumes using AWS EC2 Console or AWS APIs to avoid storage charges for unused EBS volumes.
