AWS is a secured cloud service platform that offers computing power. This is where we can run an EC2 instance for our master and slave, and then for the Marathon framework. It offers database storage as well.

We will use a MySQL database that offers more functionality to help the environment scale and grow.

For creating a VPC, EC2 instance, security groups, and load-balancers, perform the following steps:

1. Create a Virtual Private Cloud:

2. Create an EC2 instance: two for Marathon, three for Mesos master servers, and three for the Mesos slave servers:

3. Install the Mesos master application, Marathon:

4. Install ZooKeeper:

5. Insert Docker to run Docker images on all the slave servers. We will install the Mesos slave as well:

6. Use Marathon to deploy the application, and those tasks will launch on slave servers. We will use a WordPress Docker container:

Also, we will see how to load-balance Marathon and Mesos master servers. This will help to manage the Mesos UI and Marathon UI. It is not necessary to go every time on each Marathon server as the load-balancer will take care of that. If one of the master servers is down, it will redirect to another one, so this is where your management will become easy:

Use Marathon-lb HAProxy to load-balance your application request:

This was a quick overview of what we are going to cover in the upcoming chapters.
