This tutorial will show you how to create a High Availability HAProxy load balancer setup on the cloud provider, with the support of a Floating IP and the Corosync/Pacemaker cluster stack. The HAProxy load balancers will each be configured to split traffic between two backend application servers. If the primary load balancer goes down, the Floating IP will be moved to the secondary load balancer automatically, allowing service to resume.
As businesses and other organizations increasingly depend on internet-based services, attention is being focused on creating reliable infrastructure that minimizes costly downtime. In this article, we will discuss three areas where improvements could lead to less downtime for your organization. These areas are monitoring and alerting, software deployments, and high availability.
Sharded databases have been receiving lots of attention in recent years, but many don’t have a clear understanding of what they are or the scenarios in which it might make sense to shard a database. This conceptual article goes over what sharding is, some of its main benefits and drawbacks, and also a few common sharding methods.

In this article, we will see how to exploit some of the truly excellent and unique possibilities offered by the cloud provider’s global cloud server / data-centre infrastructure to have a geographically-distributed, highly-available application set-up for minimal downtime (and thus dataloss) by managing DNS responses.
Keepalived is a service that can monitor servers or processes in order to implement high availability on your infrastructure. In this guide, we will use the `keepalived` daemon to monitor two web servers. The secondary server will take over the web traffic if the primary server experiences issues by automatically claiming ownership of a shared Floating IP address using the cloud provider API.
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.

Once your application is up and running in a cloud server environment, you may be wondering how you can improve your server environment to make the leap from “it works” to a full-fledged production environment. This article will help you get started with planning and implementing a production environment by creating a loose definition of “production”, and by showing you some components that you can add to your existing architecture to make the transition.
