Globally unique resources that provide access to data management services and serve as the parent namespace for the services.
The price difference between GPv1 and GPv2 is account-specific and depends on your storage usage patterns.
In general:
- GPv2 typically provides lower capacity (storage) pricing than GPv1.
- Transaction charges are billed differently in GPv2, with pricing varying by operation type and access tier (Hot, Cool, Archive), whereas GPv1 uses a simpler transaction model.
- As a result, accounts with large amounts of stored data and relatively few transactions often see cost savings after upgrading, while highly transactional workloads should be evaluated more carefully.
To estimate the impact for your account:
- Use the Azure Pricing Calculator and compare GPv1 and GPv2 pricing for your region and redundancy option.
- Review your storage account metrics, especially Transactions, over at least one full billing cycle.
- In Azure Monitor Metrics, split transaction data by API Name to understand whether your workload is primarily reads, writes, or listing operations, since these can affect GPv2 costs differently.
- Consider whether you will benefit from access tiers (Hot, Cool, Archive) and Azure Storage Reserved Capacity, both of which are available with GPv2 and can further reduce long-term costs.
Also keep in mind that the upgrade from GPv1 to GPv2 is a one-way operation, so it is worth validating expected costs and access tier settings before migrating.
