You can now simplify the task of running a cost effective fleet of Amazon EC2 Spot Instances by targeting multiple instance types in a single Spot fleet request. Starting today, you can include up to 20 launch specifications using the new RequestSpotFleet action. Previously, each Spot Instance request could accept only one instance type with a single launch specification.
Including multiple instance types in your fleet request can help lower your operational costs and improve your application availability. For example, if your application typically runs on c4.xlarge compute-optimized instances, but also performs effectively on c3.2xlarge, m3.2xlarge, and c4.2xlarge instances, you can target a broader set of instance types to launch your fleet in the lowest-priced pools.
You can request a fleet of Spot Instances into EC2-Classic, your default VPC, or an individual VPC subnet, in all regions except the AWS GovCloud (US) region and on all instance types available as Spot Instances today. To get started, request a fleet using the AWS SDKs or Command-Line Tools.
