For several years, Azure users have been able to significantly reduce the price of virtual machines by purchasing Reserved Instances (RI). Microsoft is slashing the price of Azure computers - in some cases by as much as 72 percent - in exchange for paying upfront compute costs of one to three years.
Now,How Reserved Instances reduce the cost of Azure VMs, Azure Storage Reserved CapacitypromiseReduce the cost of Azure Blob Storage.
It seems very simple.
Assuming you've committed to long-term data retention in Azure and can afford itcapital outlayswhy don't you want to lower your storage costs?
However, there are some key requirements for Azure Storage reserved capacityforwardgo buy it.
Carrot: potential for significant cost savings
Let's look at the main motivation for using Azure reserved storage capacity: cost savings.
Figure 1. Azure Storage reserved capacity savings.
as you can see,Azure Storage reserved capacityHave a measurable impact on spending on Azure. Here's another look at the data arranged in tabular form:
Table 1. Monthly comparison of storage costs per GB of reserved Azure storage capacity.
as you can see,Savings using Azure Storage reserved capacity are very attractive - 34% savings on hot and cold tiers and 17% on archive tiers.
Given the huge savings, especially on hot and cold tier data, why not just buy reserved capacity? What is a stick?
Item 1: Make sure you are actually storing the blob
While this may seem obvious, an important first step is to ensure that your data in Azure Blob Storage is actually eligible for reserved capacity savings. There's nothing more irritating than making a large prepaid purchase only to find out it doesn't work.
To apply Azure Storage Reserved Capacity to data in Azure, you must:
- Make sure the data is thereblob storage.For Azure Storage, a lot of data may not be a blob.Azure Storage reserved capacity can only be used for blobs or data from Azure Data Lake Storage Gen2.
- Make sure you're not using a premium storage account.Premium storage accounts, even blobs in premium storage accounts, don't support reserved capacity.
In other words, the following items do not apply to reserved capacity savings: Premium Storage Accounts, General Purpose v1 (GPv1) Storage Accounts, Azure Data Lake Storage Gen1, Page Blob, Azure Queue Storage, Azure Tables, and Azure Files.
Stick 2: Is it economically viable for your level?
As you can see in the chart above, the savings on data stored in the hot and cool tiers are around 34%, assuming a 3-year upfront payment. For many companies, this is enough to justify the initial capital expenditure.
However, the situation looks less encouraging when it comes to the archival layer. Saving 17% and 3 years upfront, there's a hard question to ask:17% savings really worth investing 3 years in advance? While this varies from company to company, I think for many the answer is no.
However, there is a really nice option available:You can choose to be billed monthly for Azure Storage reserved capacity at no additional cost! This basically makes the whole opex vs capex thing moot as you can use any model with reserved capacity.
Having said that, here's another point: is there an option to cancel early? if you doMicrosoft will charge a cancellation fee of 12%.for the remainder of the term. If you think you might want to cancel sooner, please be aware of this before proceeding.
Stick 3: Get the saved data first
At Veritas, we've noticed a pattern in some of our customer conversations. From the beginning, these customers wanted to take advantage of the cost savings associated with reserving Azure storage capacity.
The problem is that often these customers are in the early stages of deployment and are still busy entering data from the registry into Azure Blob Storage accounts managed by Veritas.Azure Storage reserved capacity works on a use-or-lose basiswhich means if you prepay for 1 PB of reserved capacity and use less than that amount,Unused reserved capacity is not transferred, it is simply lost.
The obvious requirement here is to delay the purchase of reserved capacity until the data is processed. That said, a tiered approach also makes sense, where you buy blocks of reserved capacity when you reach a certain threshold. The size of these limits basically comes down to the smallest commit that allows for reserved capacity, which we'll discuss next.
Stick 4: Store enough data
The minimum Azure Storage reserved capacity commitment is 100 TB. This means that if you store less than 100 TB, you end up with unused capacity that is just wasted.
Nothing shocking here; a clear requirement is to have at least 100 TB of data before considering reserved capacity.
Step 5: Make sure the level of access and redundancy suits you
When purchasing Azure Storage Reserved Capacity, you must choose:
- sign.
- Disk size (100 TB or 1 PB drives).
- zone.
- access layer.
- Redundancy level.
All five of these ingredients block their retention capacity and only apply to sites that meet these criteria. So now the bar is raised:You not only need at least 100 TB of data, but also 100 TB more with the same subscription, region, access level and redundancy.
Figure 2. Buying Reserved Capacity from Azure Storage.
What happens if you decide to change your data access level or redundancy level after purchasing reserved capacity? APPROX,The affected data will no longer be eligible for the reserved capacity, and will be charged at Pay-Ahead (PAYGO) rates, and unused reserved bandwidth is forfeited.
This means you must be absolutely sure that the level of access and redundancy is right for you before you decide to purchase Azure Reserved Storage capacity.
Clause 6: Do not include operations
Another important consideration is that the savings you get from reserved Azure storage capacity is not a percentage of the total cost, but only a portion of the storage. Reserved capacity is not available for operations and all operations will continue to be billed on a pay-as-you-go basis.
This may seem like a minor issue, but at Veritas, customers with billions of objects are surprised to realize that they are saving less than they expected by reserving capacity. This doesn't mean they still don't save with reserved capacity, it's just that the actual storage cost savings they achieve is only a fraction of the total cost of Azure Blob Storageaccount.
at the end
While Azure Storage Reserved Capacity can provide incredible cost savings for many businesses, there are some issues. Please consider these requirements carefully before deciding to purchase reserved capacity.

Azure Archive Storage offers low-cost, durable, and highly available secure cloud storage for rarely accessed data with flexible latency requirements. Archive Storage provides secure data transfer to the cloud using HTTPS, and automatically secures that data at rest using 256-bit AES keys.
Under which circumstance should you configure your blob storage account as a hot storage tier? ›You should configure your blob storage account as a hot storage tier when your data is accessed frequently, requires low latency, and is actively in use, such as for big data analytics, content delivery, backups, and telemetry data.
When might you use Azure file storage? ›Azure Files can be used to replace or supplement traditional on-premises file servers or network-attached storage (NAS) devices. Popular operating systems such as Windows, macOS, and Linux can directly mount Azure file shares wherever they are in the world.
What is the disadvantage of Azure files? ›Azure file shares require using the storage account key, which provides access to your entire storage account.

In which scenario would you choose blob storage over files storage? ›Blob storage is optimized for storing massive amounts of unstructured data, such as text or binary data.
What is the difference between block blob and page blob? ›They are named block blobs because files larger than 100 MB must be uploaded as small blocks, which are then consolidated (or committed) into the final blob. Page blobs are used to hold random-access files up to 8 TB in size.
Why might you prefer Azure data storage over an on premises solution? ›
Azure is recommended not only because it is popular, but because it makes sense for your business.
