Get vCPU count for a given AWS instance type in Go using AWS client

I've the AWS instance type(e.g. c5.18xlarge etc.) in my config files. During runtime, I would like to fetch the number of vCPUs(e.g. 72) from here: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/cpu-options-supported-instances-values.html and do some computations and launch instances based on the number of vCPUs. I can store this data from the webpage in a map and refer the map, but is there a way to fetch this information from AWS using AWS go client?

You can use DescribeInstanceTypes

For example:

package main

import (
    "fmt"

    "github.com/aws/aws-sdk-go/aws"
    "github.com/aws/aws-sdk-go/aws/session"
    "github.com/aws/aws-sdk-go/service/ec2"
)

func main() {
    sess, _ := session.NewSession(&aws.Config{
        Region: aws.String("eu-west-1")},
    )

    svc := ec2.New(sess)

    resp, _ := svc.DescribeInstanceTypes(&ec2.DescribeInstanceTypesInput{})

    for _, v := range resp.InstanceTypes {
        fmt.Println(*v.InstanceType, v.VCpuInfo)
    }

}
