Google is giving developers a new storage option in its cloud. Cloud Filestore, which will launch into beta next month, essentially offers a fully managed network attached storage (NAS) service in the cloud. This means that companies can now easily run applications that need a traditional file system interface on the Google Cloud Platform.

Traditionally, developers who wanted access to a standard file system over the kind of object storage and database options that Google already offered had to rig up a file server with a persistent disk. Filestore does away with all of this and simply allows Google Cloud users to spin up storage as needed.
