Chapter 7

1. a: Orchestrators will not know anything about your application logic. On the other hand, we have quickly reviewed the interfaces that use orchestration to ensure that containers get the appropriate volumes of data on distributed environments.
2. c: Orchestrators will not manage application data, nor do they know anything about your application logic. The orchestrator will take care of the application components' health and will run a new instance if one of the required instances dies.
3. a and b: Distributed environments will help us to deploy applications with high availability and improved performance. But on the other hand, we will have new challenges because we need to be able to distribute application logic and components' interactions on different nodes.

4. a and b: Answers a and b are correct, while c is not, because application components can be managed one at a time. Therefore, upgrades will only impact one application component if the application logic knows how...
