Techniques for atomic live updates to operating systems are described herein. For example, a computing system can generate a first version of a binary large object (BLOB) file indicating first metadata for each file of a first version of an image for an operating system. The computing system can generate a second version of the BLOB file indicating second metadata for each file of a second version of the image. The second version can include new files associated with an update to the operating system. The computing system can execute the update to the operating system by remounting, by a file system for the operating system, the second version of the image of the operating system using the second metadata of the second version of the BLOB file.

A file system executing on a computing device may store a placeholder for a file on secondary storage of the computing device. The placeholder may comprise a sparse data stream containing none or some of the data of the file and information which enables the remotely stored data of the file to be retrieved from the network. As some or all of the data for the file is being stored remotely, the computing device may rely on a storage virtualization provider to create metadata for the file. Thus, the file system executing on the computing device may receive, from the storage virtualization provider, a request to store metadata associated with the file. In response to this request, the file system may store the metadata as a Binary Large Object (BLOB) in a secondary data stream of the placeholder for the file.

A data platform provides for encryption of secrets. During operation, an application of the data platform receives a secret and communicates the secret to an encryption client of the data platform. The encryption client generates an encrypted secret using a Data Encryption Key (DEK) and the secret. The encryption client communicates the DEK to an encryption server of the data platform while retaining the encrypted secret. The encryption server generates an encrypted DEK using a Transit Encryption Key TEK. The encryption server communicates the encrypted DEK to the encryption client and the encryption client generates a binary large object (blob) using the retained encrypted secret and the encrypted DEK. The application stores the blob on a data storage device.
