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.
Docker Swarm is the Docker-native solution for deploying a cluster of Docker hosts. You can use it to quickly deploy a cluster of Docker hosts running either on your local machine or on supported cloud platforms. Before…
This tutorial will cover setting up a Hadoop cluster on the cloud provider. The Hadoop software library is an Apache framework that lets you process large data sets in a distributed way across server clusters through leveraging basic programming models….

In this tutorial, we’ll show you how to use Ansible, a configuration management tool, to install a production Elasticsearch cluster on Ubuntu 14.04 or CentOS 7 in a cloud server environment. We will build upon the Ansible and Tinc VPN tutorial to ensure that your Elasticsearch nodes will be secure from computers outside of your own network.
In this guide, you will configure an active-active MariaDB Galera cluster. For demonstration purposes, you will configure and test three Debian 9 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.
MySQL cluster is a software technology which provides high availability and throughput. In short, there is one or more management nodes which control the data nodes (where data is stored). After consulting with the management node, clients (MySQL clients, servers, or native APIs) connect directly to the data nodes.
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.
In this guide, you will configure an active-active MariaDB Galera cluster. For demonstration purposes, you will configure and test three Ubuntu 18.04 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.
