Abstract: Techniques for a code reviewer service to provide recommendations on source code are described. A code reviewer service may run rules and/or machine learning models to provide the recommendations. A machine learning model may identify one or more predicted issues of source code, and the code reviewer service may provide one or more recommendations based at least in part on the one or more predicted issues. Code reviewer service may allow a pull request for a code repository to trigger the generation of recommendations for the source code in the repository. The recommendations may be posted on the pull request.

Abstract: A method for selecting a communication protocol for a virtual desktop instance in a service provider environment may include providing to a client computing device, access to a virtual desktop instance running on a server computer using a first communication channel associated with a first communication protocol. A request for functionality from a user of the device is detected, the requested functionality being unsupported by the first communication protocol. A second communication protocol from a plurality of available communication protocols may be selecting based on the requested functionality. The second communication protocol may support the requested functionality. A user authorization for using the second communication protocol can be verified.

Abstract: Virtual workspaces can be provided using shared resources and network-attached storage. A workspace client can access a virtual workspace created under a customer account. For specific types of data, such as pixel data used to render the display component of the workspace on the workspace client, the data can be prevented from being transmitted over a public network. Private security gateway interfaces can be created in the customer environment that can be attached to respective security gateways in the workspace environment. Routing rules are configured such that pixel data for a workspace is only transmitted to the workspace client through a security gateway and over a secure connection to the corresponding private gateway interface in the customer environment, which can direct the pixel data to the workspace client.
