Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for validating software functionality. In some implementations, data indicating a configuration of a first server environment running a third-party installation of a first version of an application is obtained. A second server environment is generated and is configured to run the first version of the application. The second server environment can be configured to use a set of configuration settings for the first server environment that are indicated by the data for the first server environment. An installer for a second version of the application to transition the second server environment to the second version of the application is run. Capabilities of the second version of the application are evaluated using a series of tests for the application on the second server environment.

Abstract: One or more computers receive a request from a user to change a configuration of a computing environment provided by one or more servers. In response to receiving the request and before performing the requested change in the configuration of the environment, the computers determine an estimated measure of performance that represents a level of performance of the computing environment if changed according to the request and provide data indicating performance measures indicating the estimated measure of performance for the environment corresponding to the change in the configuration of the environment. After providing the data indicating the estimated performance measures, the computers receive data indicating user input confirming the request to change the configuration of the environment, and perform the requested change in the configuration of the computing environment.

Abstract: Disclosed is an improved approach to implement virtualization objects in a virtualization system.

To implement this, the virtualization object can be mounted as a target (implemented as a snapshot) that is locally accessible to the host.

Abstract: A method for generating a set of concepts related to a target concept includes accessing a set of candidate concepts, embedding the target concept and the set of candidate concepts in a semantic vector space, selecting one or more intermediate concepts from the set of candidate concepts in response to determining whether each embedded candidate concept in the set of embedded candidate concepts satisfies a predetermined relationship with the embedded target concept, and filtering the one or more intermediate concepts to yield the set of concepts related to the target concept. The method may further include generating a multiple-choice question in which the target concept corresponds to a correct answer choice and the set of concepts related to the target concept correspond to distractors.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for monitoring performance of computing systems. In some implementations, a set of tasks for a server system to perform is identified. Multiple performance testing cycles are performed, in which each of the performance testing cycles includes: sending, for each task in the set of tasks, a request for the server system to perform the task; receiving a response from the server system for each of the requests, and storing a performance measure for each of the tasks based on the response received from the server system for the task. Based on the performance measures for the multiple performance testing cycles, an evaluation is performed whether conditions are satisfied for adjusting one or more operating parameters of the server system or for providing a notification regarding the operation of the server system.
