Data Operations: Charges apply for read, write, and delete operations. The cost varies by tier and operation type.
Data Transfer:
- Data In: Generally free into Azure.
- Data Out: Charges apply for data egress from Azure to the internet. Data transfer within the same Azure region is typically free.
Redundancy Options: You can choose different redundancy options (LRS, ZRS, GRS, RA-GRS) which impact the monthly storage cost.
Capacity Reservations: Reserve capacity for predictable workloads and potentially lower costs.
Important Note: Pricing is an estimate and can vary significantly by region. Always refer to the official Azure Blob Storage pricing page for the most accurate and up-to-date information. Transaction costs for Archive tier are higher due to the longer retrieval times.
