title: Latency between services in google app engine
body: <p>I would like to break out my app hosted on Google app engine into various services, and use other runtimes.</p>
  
  <p>The purpose is for performance, the information I cannot find is what is the latency between different services within a single google app engine application. To clarify I am interested in the communication latency as using HTTP.</p>
  
  <p>Also what would be the latency between GAE and another Google service such as functions or Run?</p>
