About EC2 and S3 Regions of Deployment for Amazon
InstallAnywhere 2021
The creation of an S3 bucket (which you upload files to) on the AWS Management Console is region-specific. Amazon has given you the flexibility to create data buckets at seven different regions across the world:
| • | US East (Northern Virginia) Region |
| • | US West (Northern California) Region |
| • | US West (Oregon) Region |
| • | South America (Sao Paulo) Region |
| • | EU (Ireland) Region |
| • | Asia Pacific (Tokyo) Region |
| • | Asia Pacific (Singapore) Region |
Note:It is always beneficial to deploy the AMI to the region that is closest to your customer base. For example, if your business runs in South America only, it is best to base your deployed AMI in the Sao Paulo region. This results in faster response times. Also, both the S3 bucket and AMI instance would be deployed to the corresponding region, which would help customers reduce costs.
You can create an S3 bucket in any of these regions. Amazon guarantees that the S3 bucket will be created in the respective region and that the user-uploaded files will be stored in the specified region.
The same region specification applies to EC2 as well. The launching and running of EC2 instances can be done in any of these regions.
Tip:To avoid cost overhead of data transmission from S3 bucket to instance launch region and also to make instance launching more efficient by avoiding data transmission time-overhead, it is advised that the S3 bucket creation and running of EC2 instances should be done in a same region.
Specifying the Amazon Instance Region
You can specify your S3 and EC2 region settings by making a selection in the Select the region for deployment list on the Appliance Configuration tab of the Build Appliances view on the Build page.
