Today, Amazon AppStream 2.0 is introducing On-Demand fleets, a new type of fleet that can help you optimize your streaming costs. With this addition, you can now select between two different types of fleets when building your AppStream 2.0 streaming environment. With Always-On fleets, users get instant-on access to their applications, but you are charged streaming fees for all instances in the fleet, even if no users are connected. With On-Demand fleets, users experience a small delay accessing their first application. However, you are only charged streaming fees for instances when users are connected, and a small, fixed hourly fee for instances in your fleet that are not being used. On-Demand fleets provide an additional way to help you reduce your streaming costs while retaining the capability to use features such as auto-scaling your fleet size based on user demand, monitoring, and easy updates to your applications.
