# Managed Runtime 21.9

The B2C Commerce Managed Runtime 21.9 release.

## Release Highlights

- In this release, we introduce the Salesforce Commerce Cloud Managed Runtime.

- **[Deploy PWA Kit Storefronts with the Managed Runtime (Generally Available)](https://help.salesforce.com/s/articleView?id=commerce.managed_runtime_rn_21_9_release.htm&release=264.0.0&type=5)**  
    The Managed Runtime deploys and operates PWA Kit storefronts so that front-end teams don’t have to worry about the operational cost and complexity of running mission-critical, highly scalable infrastructure. Set up single sign-on for authentication and authorization. Manage project users and permissions, auto-scale environments to handle traffic spikes, and protect against denial-of-service attacks.
