Kubernetes is an open source container orchestration system. It allows you to create, update, and scale containers without worrying about downtime. In this tutorial, you will deploy a PHP 7 application on a Kubernetes...

Linux's mdadm utility can be used to turn a group of underlying storage devices into different types of RAID arrays. This provides various advantages depending on which RAID level is used. This guide will cover how ...

Whether you’re adding more space for data or evaluating ways to optimize database performance, this tutorial will guide you through relocating MySQL’s data directory.

Whether you’re adding more space, evaluating ways to optimize performance, or looking to take advantage of other storage features, this tutorial will guide you through relocating PostgreSQL’s data directory.

Flexible and scalable data storage is a baseline requirement for most applications and services being developed today. With today's complex deployments, containers, and ephemeral infrastructure, the days of simply sav...

In this guide, we’ll show you how to move an Apache document root to a new location which allows you to independently scale storage for different sites.

In this guide, we discuss how to use Linux's mdadm utility to manage RAID arrays and perform day-to-day administrative tasks. We cover how to start, stop, or remove RAID arrays, how to find information about both the...

The mdadm utility can be used to create and manage storage arrays using Linux's software RAID capabilities. Administrators have great flexibility in coordinating their individual storage devices and creating logical s...

A Linux container is a grouping of processes that is isolated from the rest of the system through the use of Linux kernel security features, such as namespaces and control groups. LXD lets you create and manage these ...

Velero is a convenient backup tool for Kubernetes clusters that compresses and backs up Kubernetes objects to object storage. It also takes snapshots of your cluster’s Persistent Volumes using your cloud provider’s bl...

Databases grow over time, sometimes outgrowing the space on the file system. You can also run into I/O contention when they’re located on the same partition as the rest of the operating system. RAID, network block sto...

On Ubuntu, by default, the Nginx web server stores its documents in /var/www/html, which is typically located on the root filesystem with rest of the operating system. Sometimes, though, it’s helpful to move the docum...

In this article, we will go over the specific features of a high-availability application setup and discuss its components at a high level. At the end of each section, we’ll link out to additional resources on the top...

Linux has robust systems and tooling to manage hardware devices, including storage drives. In this article we'll cover, at a high level, how Linux represents these devices and how raw storage is made into usable space...

Continuous use of SSDs results in degraded performance if not accounted for and mitigated. The TRIM command is an operation that allows the operating system to propagate information down to the SSD about which blocks ...

Whether you’re adding more space, evaluating ways to optimize performance, or looking to take advantage of other storage features, this tutorial will guide you through relocating PostgreSQL’s data directory on an Ubun...

In this tutorial, you'll use LXD to install two Nginx-based web sites on the same server, each confined to its own container. Then you'll install HAProxy in a third container which will act as a reverse proxy. You'll ...
