Google has opened a beta programme offering managed file storage for apps running in its cloud platform.

Instead of users provisioning their own storage and providing/obtaining file interface software for their apps, they can now directly mount Cloud Filestore volumes on GCP Compute Engine VMs. The Filestore is also integrated with Google Kubernetes Engine and containers can access the same data.
