Capacity reservation enables you to reserve compute capacity in an Azure region or an availability zone for any duration of time. Unlike reserved instances, you do not have to sign up for a 1-year or a 3-year term commitment. You can create and delete reservations at any time and have full control over how you want to manage your reservations.
Once the capacity reservation is created, the capacity is available immediately and is exclusively reserved for your use until the reservation is deleted.
Benefits of capacity reservation include:
- Once deployed, capacity is reserved for your use and always available within the scope of applicable SLAs
- Capacity reservation can be deployed and deleted at any time with no term commitment
- It can be combined automatically with reserved instances for term commitments discounts
