# Scale Development and Testing with XXL On-Demand Sandboxes

On-demand sandboxes for B2C Commerce stores now support Extra Extra Large (XXL) instances, designed for the most demanding commerce development and testing needs.

On-demand sandboxes for B2C Commerce stores now support Extra Extra Large (XXL) instances. XXL instances are new, high-capacity instances designed for the most demanding commerce development and testing needs. The new XXL option is an addition to the current support for XL (Extra Large), L (Large), and M (Medium) on-demand sandboxes.

XXL instances have significant CPU and storage resources to empower large-scale development and testing activities, complex integrations, and high-performance workloads.

**Where:** This change applies to B2C Commerce.

**How:** Contact your Salesforce Commerce Cloud admin for assistance with setting up and getting access permission to an XXL instance.
