The bulk of the storage capacity in the archive tier is quite inexpensive, while the highest cost factor is the data on the performance tier. Here are the monthly storage costs we should expect from this scenario in the West US 2 region: Tier The math for storage is simple: Let’s say we have 2,250 TB of data in Azure, spread across the Hot (600 TB), Cool (200 TB), and Archive (1,450 TB) tiers. As an example, here’s a look at Microsoft’s object storage pricing for their West US 2 region: However, flat rate fees are all you’ll find with the low-touch and archive tiers. Generally, these are the three main categories of storage tiers, though we anticipate providers will release additional variations and options over time.Īmong the major cloud providers today, you’ll find volume discount prices for some of the performance tiers (i.e., the monthly cost per gigabyte decreases as your data volumes passes certain thresholds). Just don’t be too aggressive with what you move to archive tiers because they have the highest activity costs and the slowest retrieval response times. Archive tiers are geared for workloads that are very unlikely to require access but indeed require long-term storage. You can wait for hours for a recall to complete, and even expedite a request for a fee. The archive tiers in the cloud are actually physical tape libraries, so retrieval times aren’t immediate, but the storage costs are incredibly low. This includes GCP’s Coldline, Glacier from AWS, or Microsoft’s Archive tier. However, activity costs increase over the performance tiers. Low-touch tiers offer availability and low-latency retrieval times with lower storage costs. Low-touch tiers are for data requiring ready access but the information is mostly inactive. This includes the S3 Standard – Infrequent Access tier from AWS, or Microsoft Azure’s Cool tier. However, these tiers also come with the highest prices for object storage. Performance tiers are designed for active or hot data that’s highly transactional, offering the best availability SLAs, lowest activity costs, and lowest latency. This includes the Hot or Premium tier of Azure Blob Storage, or the S3 Standard tier in AWS. Let’s look at the different cloud storage levels, as follows: Storage costs are the simplest math in the cloud pricing equation Egress costs do not incur when you access data from resources residing within the same region. There’s a fee for downloading data from any cloud storage where the payload delivers outside of the cloud region. This is more a network activity cost factor than a storage price variable. A per-gigabyte fee to read data, typically present with particular storage tiers. However, charges for storage operations can add up to meaningful amounts when you’re performing numerous tasks on high-object-count workloads.
API-based actions incur minimal costs, typically per 10,000 procedures. And each cloud provider has different tiers of storage that offer vastly different cost, performance, and availability levels. These costs are typically expressed as a cost per gigabyte per month or a price per terabyte per month or year. There are several cloud storage cost variables you need to be aware of, including: So, once you get familiar with the approach to cloud storage pricing, you’ll be in a better position to evaluate the cost-effectiveness of all the major cloud providers based on your organization’s needs. The fact is cloud storage pricing is complicated, it doesn’t always cost less than on-premises options, and egress charges are unlikely to be a budgeting problem for you.ĭespite the complexities of cloud storage pricing, the good news is that the object storage offerings from Amazon Web Services (AWS), Microsoft Azure, and Google Cloud Platform (GCP) all have similar pricing models for cloud storage. So, I hope to provide some clarification to help you have a better understanding of cloud storage pricing so you know what to expect. We routinely see people express confusion about cloud storage pricing. With all the talk about the lower costs of cloud storage (outside of variable egress fees), how do you figure out what’s best for your organization?
What’s more, the process of untangling the pricing of cloud storage services can cause confusion and frustration.
It’s no secret the cost of ownership model for on-premises storage is nothing like the way enterprise cloud storage pricing works.
