US Patent 9935828 Application controller to support incremental deployment

A system includes reception of a request associated with a cloud-based application at an external port of a container associated with the cloud-based application, passage of the request to an application controller associated with the cloud-based application, determination of whether the request includes a command to modify the cloud-based application, invocation of a function to execute the command if it is determined that the request includes a command to modify the cloud-based application, and forwarding of the request to the cloud-based application at a second port different from the external port if it is determined that the request does not include a command to modify the cloud-based application.
