@saturnism @googlecloud #kubernetes Challenges Which host machine(s) should each service run on? Avoid port conflicts? How does the application code find the Guest Book service? How do we keep all of these service running? What happens if a host machine has trouble? Are the services healthy? How do we scale when load changes? Run this in another environment? QA, dev, another cloud, your servers?
