Changing Environment Type

In AWS Toolkit for Eclipse, the Environment Type section of your environment's Configuration tab lets you select either Load balanced, auto scaled or a Single instance environment, depending on the requirements of the application that you deploy. For an application that requires scalability, select Load balanced, auto scaled. For a simple, low traffic application, select Single instance. For more information, see Environment Types.
