If you use CentOS as the L in your LAMP stack, you may be wondering what to do after Red Hat’s announcement. Let’s look at a new community distro that aims to provide a replacement for CentOS.

Docker Swarm is a mode in which Docker deploys container services across a cluster. Spreading a service across multiple swarm nodes (systems running Docker joined to the same swarm cluster) allows us to perform load balancing and rolling updates to our application. We also can easily horizontally scale by adding more nodes and scaling services […]

If you’ve been putting off learning how to use Docker in your PHP projects, here is your chance: we’re going to start from scratch, and we’re going to cover a lot of ground to take a PHP application from running locally to running in containers, then a cluster, and ultimately in Kubernetes. Let’s get settled […]

Virtualmin is a web hosting and cloud computing control panel. A hosting control panel is a web-based application that runs on a server and manages all the aspects of a hosting account. This includes account information, websites, web servers, databases, mail servers, and all the other services which ultimately work together to allow you to […]

This month, we’re going to dive into a practical application of Ansible by building a playbook with roles to implement a fully functional Linux, MySQL, PHP, and NGINX web server. By the end, you should be able to take the playbook we build together and extend it to suit your requirements.

Any career today requires continual learning and curiosity for success. Building web applications with PHP is not exempt. The PHP of today is light-years better than the scripts that initially made up “Personal Home Page/Form Interpreter.” In this issue, we examine moving between frameworks, understanding your mental health, contributing to open source, and more.

Ansible is an open-source IT automation tool used for configuring systems and deploying applications. Red Hat supports Ansible in the enterprise by offering support contracts and funding employees who contribute. Ansible communicates over SSH, so there is no need to install any extra software (such as PHP, Apache, NGINX, Redis, and others) on the remote […]

In recent years, a different way to build applications has arisen called serverless computing. This term is not a good name; I’m reminded of the adage that there are two hard problems in programming: naming things, cache invalidation, and off-by-one errors. Serverless computing as a name implies no servers, but there are servers—you don’t think about them though. A better way to think about it is that the servers and the management of them are abstracted away and the provider manages the allocation of resources, not the application architect.

The tech industry is always awash with new ideas that are actually old. One which gained traction in the last ten years is the idea of “DevOps.” This term is the combination of “Development” and “Operations” and is meant to show these two roles can be combined for more efficiency.

Your job doesn’t end when you finish writing and committing code. Someone has to ensure a web application is available online, scalable, and secure. This issue collects articles to help you improve and fine-tune your DevOps processes.
