[Google Pipelines API](https://cloud.google.com/genomics/v1alpha2/pipelines “Google Pipelines API”) (PAPI) formerly known as JES, is used when launching an analysis. PAPI starts a virtual machine per task and provides the inputs, the WDL telling it what to do, the environment to do it in (the Docker image), and requests the outputs when it’s done. Each virtual machine’s (VM) requirements can be specified in the task (RAM, disk space, memory size, number of CPUs) and once the task is done, the VM will shut down.
