Defender for Storage cost optimization

Hi Eelco510,

I will try to summarize the advantages and disadvantages of using the script on the first day of the month and on the last day of the month.

Running on the First Day of the Month:

Advantages:

1. Up-to-Date Information: You'll have access to the most current and accurate usage data from the previous month, which is essential for well-informed decision-making.

2. Sufficient Time: With the entire month ahead, you can take your time to analyze data, make informed choices, and implement changes, ensuring effective cost optimization.

3. Maximized Savings: Initiating optimization on the first day enables you to enjoy the benefits of an optimized plan for the entire billing period, potentially leading to the highest cost savings.

Disadvantages:

1. Immediate Workload: It might require more immediate attention and effort on the first day, especially if you have numerous storage accounts to review and optimize.
   
   
   

Running on the Last Day of the Month:

Advantages:
Reduced Immediate Workload: You can set up the script and have fewer immediate responsibilities for most of the month, as it's scheduled to run on the last day.

Disadvantages:

1. Time Constraints: There's less time available for analyzing data, making decisions, and implementing changes before the new billing cycle begins. This could result in hasty decision-making.

2. Missed Savings Opportunities: Delaying optimization decisions until the end of the month may lead to missed chances for cost savings since the optimized plan won't be in effect for the entire billing period.

3. Billing Data Lag: Usage data may not be completely finalized by the last day of the month, potentially leading to less accurate cost optimization decisions.

In summary, running your cost optimization script on the first day of the month provides the advantages of current data, enough time for optimization, and the potential for maximum savings.

On the other hand, scheduling it for the last day of the month reduces immediate workload but carries the risk of rushed decisions and potential missed savings.
