IAM Roles for EC2 - Overview
IAM Roles for EC2 allow you to access Amazon S3 storage from EC2 without transferring your Access Key ID and Secret Access Key to the instance.
You define the Role in your IAM AWS Console and launch the EC2 instance with this role. Applications running on such instance are now able to obtain temporary Access Keys from instance metadata. These access keys are rotated during the day providing you an additional layer of security.
To connect to Amazon S3 from EC2 via IAM Role:
1. Start TntDrive and click Add New Mapped Drive.
Click the [Add New Mapped Drive] button
Add New Mapped Drive dialog will open:
Add New Mapped Drive dialog.
2. Specify Amazon S3 on EC2 via IAM Role storage type and the Bucket and click Add new drive.
