    Abstract: In one embodiment, a system for managing a virtualization environment includes a set of host machines, each of which includes a hypervisor, virtual machines, and a virtual machine controller, one or more virtual disks comprising a plurality of storage devices and accessible by the virtual machine controllers, and a deployment system configured to receive a request to upgrade a virtualized file server on a plurality of host machines from a first program code version to a second program code version, and, for each host machine, request an upgrade token. When the host machine acquires the upgrade token, the deployment system is configured to generate a snapshot of a code image associated with the second program code version, and provide the snapshot to the host machine via the virtual disk. The virtual machine controller located on the host machine stores the snapshot on a storage device associated with the host machine.

    Abstract: Examples described herein may provide local key managers on computing nodes of distributed computing systems. The local key managers may protect secrets (e.g. cryptographic keys) in the distributed system such that risk of compromise is reduced or eliminated. The local key managers may utilize a master key to protect secrets. The master key may be protected by generating multiple key shares using a key sharing technique (e.g., Shamir's secret sharing). The multiple key shares may be stored on different nodes in the distributed computing system. In some examples, secure processors, such as trusted platform modules (TPMs), may be incorporated in computing nodes of distributed computing systems described herein. The secure processor may aid in securely protecting cryptographic keys in the event of disk or node theft, for example.
