Functions

func GetConfigProvider

func GetConfigProvider(config Config) (client.ConfigProvider, error)

c := Must(GetConfigProvider(Config{}))

func NewCostCalculatorEC2

func NewCostCalculatorEC2(api pricingiface.PricingAPI) calculator.CostCalculator

NewCostCalculatorEC2 initializes a new cost calculator for AWS EC2 resources.

func ParseEC2

func ParseEC2(product map[string]interface{}) (calculator.Rate, error)
