Functions

func NewPricingAPI

func NewPricingAPI(sess *session.Session, region string) pricingiface.PricingAPI

NewPricingAPI returns a pricing API configured based on a particular region

Types

type Provider

type Provider struct {
	// contains filtered or unexported fields
}

Provider provides actual pricing data to the AWS cloud provider to allow it to make more informed decisions regarding which instances to launch. This is initialized at startup with a periodically updated static price list to support running in locations where pricing data is unavailable. In those cases the static pricing data provides a relative ordering that is still more accurate than our previous pricing model. In the event that a pricing update fails, the previous pricing information is retained and used which may be the static initial pricing data if pricing updates never succeed.
