Scheduling a Powershell script to run weekly in AWS - amazon-web-services

Question

So, I've got the following powershell script to find inactive AD users and disable their accounts, creating a log file containing a list of what accounts have been disabled:
Import-Module ActiveDirectory
# Set the number of days since last logon
$DaysInactive = 60
$InactiveDate = (Get-Date).Adddays(-($DaysInactive))
# Get AD Users that haven't logged on in xx days
$Users = Get-ADUser -Filter { LastLogonDate -lt $InactiveDate -and Enabled -eq $true } -
Properties LastLogonDate | Select-Object #{ Name="Username"; Expression=.
{$_.SamAccountName} }, Name, LastLogonDate, DistinguishedName
# Export results to CSV
$Users | Export-Csv C:\Temp\InactiveUsers.csv -NoTypeInformation
# Disable Inactive Users
ForEach ($Item in $Users){
$DistName = $Item.DistinguishedName
Disable-ADAccount -Identity $DistName
Get-ADUser -Filter { DistinguishedName -eq $DistName } | Select-Object #{ Name="Username"; Expression={$_.SamAccountName} }, Name, Enabled
}
The script works and is doing everything it should. What I am trying to figure out is how to automate this in an AWS environment.
I'm guessing I need to use a Lambda function in AWS to trigger this script to run on a schedule but don't know where to start.
Any help greatly appreciated.

I recomment to create a Lambda function with dotnet environment: https://docs.aws.amazon.com/lambda/latest/dg/lambda-powershell.html
Use a CloudWatch Event on a Scheduled basis to trigger the function:
https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/RunLambdaSchedule.html
An alternative, if you like to to have a more pipeline style execution you could use CodePipeline and CodeBuild to run the script. Use again CloudWatch to trigger the CodePipeline on a scheduled basis!
