Microsoft Introduces Capacity Reservation Groups in Public Preview on Azure

Microsoft Announces Public Preview for Sharing Capacity Reservation Groups

In an exciting development, Microsoft has unveiled the public preview of a new feature that allows for the sharing of Capacity Reservation Groups (CRGs) across multiple Azure subscriptions. Previously, organizations were limited to deploying virtual machines (VMs) within the same subscription, but this update enhances flexibility and resource management across different accounts.

Benefits of Capacity Reservation Sharing

This new capability simplifies configuration management significantly. Key advantages include:

  • Resource Reuse: Organizations can effectively share reserved resources across various subscriptions.
  • Centralized Capacity Management: Administrators can oversee reserve allocations more efficiently.
  • Cost-Effective Scaling: Enhanced sharing allows for a more economically viable scale-out process.
  • Separation of Security and Capacity: This feature also helps in managing security concerns independently from capacity management.

Understanding Azure Capacity Reservations

For those unfamiliar with the concept, Azure’s capacity reservations permit users to allocate and control the compute resources essential for running virtual machines. With the current update, administrators now have the capability to hold onto a reservation for any desired length of time, across any public Azure region or availability zone, supporting a majority of virtual machine series. It’s noteworthy that Microsoft allows users to create and cancel these on-demand capacity reservations at their convenience, eliminating the need for long-term commitments.

Requirements for Sharing Reserved Capacity

To utilize the shared capacity reservation feature, users will need to set up at least two subscriptions:

  1. Provider Subscription: This subscription is responsible for creating and hosting the CRG.
  2. Consumer Subscription: This grants the access necessary to utilize the CRG for deploying VMs under the Capacity Reservation Service Level Agreement (SLA).

Current Limitations to Consider

Despite its promising functionalities, users should be aware of a couple of limitations:

  • Portal Support: Currently, there is no support for the Azure Portal; however, users can utilize the API and other Azure clients.
  • Re-provisioning Restrictions: During a zone outage, re-provisioning of Virtual Machine Scale Set (VMSS) VMs that utilize a shared CRG is not supported.
