Until now, we have looked at a very basic architecture, featuring just one master server and one Marathon server, which, together, form our development environment. But now, as we have to develop a production environment, we will have to add more components. Accordingly, our plan of action includes the following:
- Adding one Marathon server
- Adding two more master servers
- Adding three slave servers
This will cause our architecture to look like the following:
The packages that we will need to install on each of the components should be evident from the architecture shown in the above diagram. For Marathon servers, we will need to install the Marathon package; for Masters, we will install ZooKeeper; and on the slaves, we will install Docker, which is a container that will enable our applications to run. This is how we will be distributing our package installation...
