Explaining Hardware Virtualization and Containerization

Virtualization is the abstraction of a computer resource—such as hardware, memory, storage, an operating system, a desktop machine, or a network—built on top of the physical resource. There are many types of virtualization, and here, we look at virtualization of hardware and of an operating system, or containerization.

Selecting a Database for Your Data Needs

Data requirements vary, and with so many different types of databases, selecting which to use can be a tricky choice. It all depends on what your database will be used for, the data structure, and the scale of data. Let’s look at six popular database types so you can decide which would be best for your situation.

Agile Is Not the Same as DevOps

Agile and DevOps are two terms that are often confused with each other and sometimes used interchangeably. But they are not the same idea. While both improve software performance, these concepts are actually quite different. Let's look at their definitions, origins, and principles, as well as using each in practice.

Using a Multibranch Jenkins Pipeline with Docker

Typically, code for a Docker image is developed using multiple GitHub branches, with each branch being the code for a single Docker image tag. However, having to create and run a Jenkins pipeline for each GitHub branch can be cumbersome. Try a multibranch pipeline to integrate multiple GitHub branches simultaneously.

Using the Phalcon PHP Framework with MySQL

Some PHP frameworks now support the model-view-controller (MVC) design pattern, most notably the open source Phalcon framework. Phalcon has the lowest level of overhead due to memory and CPU for MVC applications, and it supports object-relational mapping features. Here's how you can get started with Phalcon and MySQL.

Using Kubernetes Helm Charts for Increased DevOps Collaboration

A Docker image is usually designed for a baseline functionality and can then be customized. However, customized resource definitions are typically not shared among other users who might have a similar application requirement. Here’s where Helm charts for Kubernetes can help reduce rework and increase collaboration.

Why Use Kubernetes for Your Container Management?

Kubernetes is the most commonly used open source orchestration framework for containers. It’s used for automating deployment, scaling, and management of application containers and works with many container tools, including Docker. But what makes Kubernetes so popular? And would it be useful to you? Let's take a look.
