This tutorial will demonstrate how you can use Corosync and Pacemaker with a Reserved IP to create a high availability (HA) server infrastructure on the cloud provider. Corosync is an open source program that provides cluster membership and messaging capabilities, often referred…
In this guide, you will configure an active-active MariaDB Galera cluster. For demonstration purposes, you will configure and test three Debian 10 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.
Zabbix is open-source monitoring software for networks and applications. In this tutorial, you will configure a Zabbix-based monitoring system on two Ubuntu 18.04 machines. One will be configured as the server, and the other as a client that you’ll monitor. The server will use a MySQL database to record monitoring data and use Apache to serve the web interface.

Corosync is an open source cluster engine used to implement high availability within applications. This tutorial will demonstrate how to use Corosync and Pacemaker to create a high availability (HA) infrastructure on the cloud provider with CentOS 7 servers and Reserved IPs. To facilitate the process of setting up and managing the cluster nodes, we are going to use PCS, a command line interface that interacts with both Corosync and Pacemaker.
It doesn’t matter if you’re running a small blog, a large application, or an API; you never want it to be offline. A single point of failure is any part of your infrastructure that will cause downtime if it fails. A highly available infrastructure has no single point of failure. A highly available configuration is not only important for redundancy. It will also be faster and more cost effective to scale your infrastructure as well.

Prepare your eCommerce website for large traffic spikes during the holiday season, scale sales, and grow your business along the way.
In this guide, you will configure an active-active MySQL Galera cluster with three Ubuntu 18.04 servers. Clustering adds high availability to your MySQL database by distributing changes to different servers. In the event that one of the instances fails, others are quickly available to continue serving. Galera is a database clustering solution that enables you to set up multi-master clusters using synchronous replication.
