Availability of editions
All editions are available in any Amazon Web Services Region that is currently supported by Amazon QuickSight.
The capacity region in which you start your Amazon QuickSight subscription is where your account's default SPICE capacity is allocated. However, you can purchase additional SPICE capacity and access your Amazon resources in any other supported Amazon Web Services Region.
You can start a new Amazon QuickSight subscription using Standard edition, choosing any default capacity region. You can then upgrade it to Enterprise edition at any time.
To manage Enterprise account settings, you must temporarily change your region for your session to US East (N. Virginia) Region. You can change it back when you have finished editing your account settings. These settings include changing your subscription's notification email, enabling IAM access requests, editing access to Amazon resources, and unsubscribing from Amazon QuickSight.
