Frequently Asked Questions
What is Azure Blob Storage?
Azure Blob Storage is a cloud service offered by Microsoft Azure. It provides various configurations (200 pricing tiers available) with pay-as-you-go and committed-use pricing options.
How much does Azure Blob Storage cost per month?
Prices range from $0.01/month for HDD - HDD LRS Overflow Snapshot Usage to $2,691,072.00/month for E80 ZRS - E80 ZRS Disk on On-Demand pricing in eastus.
Does Azure Blob Storage have a free tier?
Azure offers various free tier options. Check the official Azure pricing page for the most current free tier details for Blob Storage.
How many Azure Blob Storage pricing tiers are available?
There are 200 pricing tiers available for Azure Blob Storage. These range from entry-level configurations to high-performance options for enterprise workloads.
What pricing models does Azure Blob Storage offer?
Azure Blob Storage offers On-Demand (pay-per-hour, no commitment), Reserved/Committed Use (1-3 year commitments for significant discounts), and in some cases Spot/Preemptible pricing for interruptible workloads at the lowest cost.
How is cloud storage pricing calculated?
Cloud storage costs include three components: storage capacity (per GB/month), API requests (PUT, GET, LIST operations), and data transfer out (egress). Infrequent-access and archive tiers offer lower storage costs but charge higher retrieval fees, making them ideal for data accessed less than once a month.
Are there data transfer costs for cloud storage?
Yes. Ingress (uploading data) is typically free, but egress (downloading or transferring data out) is charged per GB. Costs vary by provider and destination — transfers within the same region are cheapest, while cross-region and internet-bound transfers cost more.
