Abstract: Virtual workspaces can be provided using a shared resource environment. A workspace accessed under a customer account can perform an upgrade or downgrade of the operating system by building a new workspace instance instead of modifying an existing workspace instance. A workspace bundle can be obtained that includes a machine image for the target operating system, as well as configuration information and information for default applications installed for the workspace. A new workspace instance can be created using the workspace bundle and user-specific configuration information. A workspace agent can perform a simplified install of the applications using information from the prior workspace. One or more new data volumes can be created using a snapshot from the prior workspace. Once configured, the new workspace instance can be made available to the user. The process can be repeated using the prior workspace bundle if an operating system downgrade is requested.

Abstract: Virtual workspaces can be provided using shared resources and network-attached storage. A workspace accessed under a customer account has a unique key generated using a combination of a customer master key and an encryption context. The encryption context is specific to the workspace, such as may include a hash of specific values for the workspace. When a new instance is generated, a first data volume is generated using a machine image and data snapshot encrypted under a current encryption key. The snapshot is copied to a new snapshot, and a new encryption key obtained that is based on the customer master key and the current encryption context. The snapshot is used to create a new data volume encrypted under the new encryption key. The new volume is attached to the workspace instance such that data transmitted between the workspace and the new volume is encrypted under the volume-specific encryption key.
