Understanding Azure Commitment Options
Azure offers two types of commitment-based pricing for Dedicated Hosts:
-
Reserved Instances: These provide a moderate discount (20-25% savings) with slightly more flexibility in terms of deployment options.
-
Savings Plan: This option provides the deepest discounts (17-38% savings) in exchange for a longer-term commitment to using Azure services.
Important Notes:
- These prices are indicative only and based on Azure's East US region pricing for DCsv2-Type1 Dedicated Hosts.
- Each Virtual Signer instance runs in its own isolated VM for maximum defense-in-depth security.
- The Dedicated Host is charged at the host level regardless of how many VMs are running.
- Commitment terms affect pricing significantly:
- 1-year Reserved Instances offer ~20% savings
- 1-year Savings Plan offers ~17% savings
- 3-year Reserved Instances offer ~25% savings
- 3-year Savings Plan offers ~38% savings
- While it's possible to run multiple Virtual Signers on a single VM, we recommend maintaining VM isolation for enhanced security.
Prices shown are based on Azure pricing as of the calculation date. Please check the Azure Dedicated Hosts pricing calculator for current rates and to explore pricing for other regions.
Actual pricing may vary depending on the type of agreement entered with Microsoft, date of purchase, the region chosen, and the currency exchange rate.
