In this guide, you will configure an active-active MariaDB Galera cluster. For demonstration purposes, you will configure and test three CentOS 7 Droplets that will act as nodes in the cluster. MariaDB is an open source relational database system that is fully compatible with the popular MySQL RDBMS system. Galera is a database clustering solution that enables you to set up multi-master clusters using synchronous replication.
Mesosphere is a software solution that expands upon the cluster management capabilities of Apache Mesos with additional components to provide a new and novel way to manage server infrastructures. In this tutorial, we will briefly explain what each key component of Mesosphere does, starting with Apache Mesos, and show how each is used in the context of Mesosphere.

Etcd is a globally distributed key-value store that is available in CoreOS installations. By registering services in this store, related applications can adjust their configuration based on the values available. In this guide, we will demonstrate how to configure `confd` to monitor `etcd` in order to dynamically generate an Nginx configuration. Continuous polling of `etcd` allows us to configure Nginx as a load balancer that adjusts its list of backend servers as they are started or stopped.

The fleet daemon and the fleetctl utility program are essential for managing your CoreOS cluster. A cluster-wide interface to individual systemd instances, this system allows you to manage services throughout your clustered environment. In this guide, we’ll get familiar with these components.
Consul is a service discovery system that can be used to easily keep track of the health and availability of various parts of your infrastructure. In this guide, we will focus on getting a production-ready consul configuration set up in order to easily manage the consul processes.
