In order to automate the reserved units for the streaming service, we can use the following code in C#:

using Microsoft.WindowsAzure.MediaServices.Client;
using System;
using System.Configuration;
using System.Linq;
namespace StreamingReservedUnits
{
    class Program
    {
        static void Main(string[] args)
        {
            //0.Nuget: Install-Package windowsazure.mediaservices 
            //1. Credentials
            var AccountName = ConfigurationManager.AppSettings["AccountName"];
            var AccountKey = ConfigurationManager.AppSettings["AccountKey"];
            //2. Get Context
            var context = new CloudMediaContext(AccountName, AccountKey);
            //3. Create tasks
            for (var index = 0; index < context.StreamingEndpoints.Count(); index++)
            {
                var endpoint = context.StreamingEndpoints.Skip(index).Take(1).FirstOrDefault();
                Console.WriteLine("Endpoint {0} has {1} units", endpoint.Name, endpoint.ScaleUnits);
                if (endpoint.State != StreamingEndpointState.Scaling)
                    endpoint.Scale(0);
            }
            Console.WriteLine("Streaming endpoint units off!");
            Console.ReadLine();
        }
    }
}

It’s available an async method for this action as well: ScaleAsync. This is an example to use it:

using Microsoft.WindowsAzure.MediaServices.Client;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.Linq;
using System.Threading.Tasks;
namespace StreamingReservedUnits
{
    class Program
    {
        static void Main(string[] args)
        {
            //0.Nuget: Install-Package windowsazure.mediaservices            
            //1. Credentials and constants
            var AccountName = ConfigurationManager.AppSettings["AccountName"];
            var AccountKey = ConfigurationManager.AppSettings["AccountKey"];
            var ReservedUnits = 0;
            //2. Get Context
            var context = new CloudMediaContext(AccountName, AccountKey);
            var task = new List<Task>();
            //3. Create tasks
            for (var index = 0; index < context.StreamingEndpoints.Count(); index++)
            {
                var endpoint = context.StreamingEndpoints.Skip(index).Take(1).FirstOrDefault();
                Console.WriteLine("Endpoint {0} has {1} units", endpoint.Name, endpoint.ScaleUnits);
                if (endpoint.State != StreamingEndpointState.Scaling)
                {
                    task.Add(endpoint.ScaleAsync(ReservedUnits));
                    Console.WriteLine("From {0} units to {1}", endpoint.ScaleUnits, ReservedUnits);
                }
            }
            Task.WaitAll(task.ToArray());
            Console.WriteLine("All endpoints updated!");
            Console.ReadLine();
        }
    }
}

Also, If we want to use a Scheduler in order to launch this task every X time, you can use Azure WebJobs following this post.

Thanks to Vito for providing me the vintage version of this code. I only had to update it 😉

Cheers!
