We all know that while Microsoft provides an almost seemingly infinite amount of storage. Compare this to your normal datacentre virtual infrastructure, you often need to do some capacity planning for expected Virtual Machine Compute and Storage way ahead of time.
As Microsoft does the capacity planning for you (and everyone else who is using their services), your own Operational Support no longer needs to order disks or more servers to keep up with your business growth and expectations.
While this is great because it relieves your Operational Support guys to do other tasks, it has its drawbacks.
The main one is that your Azure storage is never managed properly or efficiently. That is until someone starts looking into ways to reduce your Azure spend.
Recently one of our Enterprise clients contacted us to help them reduce their Azure Storage Costs.
In this and a following blog post, I’ll show you exactly how they used Cloud Storage Manager and the Azure cost savings they gained.
Just running these two simple reports and then taking action on them
saved this client $33,600 in their yearly Azure Blob Storage Costs.
How did they save money on their Azure Blob Storage?
Luckily, they had installed and been using Cloud Storage Manager for a few months now, so we had a full scan completed of all their Azure Subscription and Blob Storage Accounts.
As you can see in the picture to the right, they have quite a bit of Azure Storage in use.
How much blob storage are your VM snapshots consuming?
Once the Azure Snapshot report has generated, simply open it up in excel to see all your Azure VM snapshots.
The report provides you with information including the name of the Azure snapshot, which subscription it resides in, the Azure Storage Account, the relevant Container, size of the Azure VM snapshot, when it was created, if its a managed or unmanaged disk, the Azure Resource Group, type of snapshot created and finally any Azure Tags if you have them.
From this report, we found that they had 1168 Azure VM snapshots lingering in their environment, some well over 3 years old.
Using a simple calculation in Excel using standard Azure storage costs, ($0.02750 per TB) deleting all these snapshots saved the client just under $2,000 per month, an approximate saving of $24,000 a year.
How do you find unattached Azure VM disks?
Next on the list to reduce their Azure Storage costs, was finding unattached Azure Virtual Machine disks.
Again, this is often overlooked, to delete any disks no longer needed when decommissioning your Azure VMs.
Another standard report is run, this time All Unattached Disks.
Once the report has completed, again open it up in Microsoft Excel.
Now using the same quick costing formulas from before, we can see an estimated monthly Azure Storage cost for these unattached virtual machine disks.
After running this report, we found that the client had over 110 unattached Azure Virtual Machine Disks.
Removing all these unattached disks saved them $800 per month, so around $9,600 per year.
In a follow-up blog post, we will then dig a little deeper on more Azure Storage cost-saving initiatives using the insights from Cloud Storage Manager.
