Architecture

The Cloud Controller Bridge (CC-Bridge) components translate app-specific requests from the Cloud Controller to the Diego Database. These components include the following:

• Stager

  • Translates staging requests from the Cloud Controller into generic Tasks and LRPs
  • Sends a response to the Cloud Controller when a Task completes

• CC-Uploader

  • Mediates uploads from the Rep to the Cloud Controller
  • Translates simple HTTP POST requests from the Rep into complex multipart-form uploads for the Cloud Controller

• Nsync Bulker

  • Periodically polls the Cloud Controller for each app to ensure that Diego maintains accurate DesiredLRPs counts

• Nsync Listener

  • Listens for app requests
  • Updates and creates the DesiredLRPs count and updates DesiredLRPs through the BBS

• TPS Listener

  • Provides the Cloud Controller with information about currently running LRPs to respond to cf apps and cf app APP_NAME requests

• TPS Watcher

  • Monitors ActualLRP activity for crashes and reports them the Cloud Controller
