Three Ways To Improve Your Programming Skills

The ability to write code is a huge differentiator for every job role in an enterprise Linux environment. As an Operations and DevOps manager, I was constantly challenged to improve my team’s programming skills, and the team genuinely wanted to be more proficient. But how? Structured training is a standard answer: take a course! Our company, like many, invested enormously in learning resources. I’d sit with an engineer one-on-one and we’d ponder the online portal together, puzzling out the most appropriate Python learning path.

Experts Attempt to Explain DevOps--and Almost Succeed

What is DevOps? How does it relate to other ideas and methodologies within software development? Linux Journal Deputy Editor and longtime software developer, Bryan Lunduke isn't entirely sure, so he asks some experts to help him better understand the DevOps phenomenon. The word DevOps confuses me. I'm not even sure confuses me quite does justice to the pain I experience—right in the center of my brain—every time the word is uttered.

Digging Through the DevOps Arsenal: Introducing Ansible

If you need to deploy hundreds of server or client nodes in parallel, maybe on-premises or in the cloud, and you need to configure each and every single one of them, what do you do? How do you do it? Where do you even begin? Many configuration management frameworks exist to address most, if not all, of these questions and concerns. Ansible is one such framework.

The DevOps Issue

Every few years a new term is coined within the computer industry—big data, machine learning, agile development, Internet of Things, just to name a few. You'd be forgiven for not knowing them all. Some of these are new ideas. Some are refinements on existing ideas. Others still are simply notions we've all had for a long time, but now we have a new word to describe said notions. Which brings me to a topic we cover in depth in this issue of Linux Journal: DevOps.

Continuous Integration/Continuous Development with FOSS Tools

Up your DevOps game! Get the fundamentals of CI/CD with FOSS tools now! One of the hottest topics within the DevOps space is Continuous Integration and Continuous Deployment (CI/CD). This attention has drawn lots of investment dollars, and a vast array of proprietary Software As A Service (SaaS) tools have been created in the CI/CD space, which traditionally has been dominated by free open-source software (FOSS) tools. Is FOSS still the right choice with the low cost of many of these SaaS options?

CI/CD and the New Generation of Software Delivery: an Interview with Harness

Continuous integration and continuous delivery (CI/CD) is all the rage in the modern world of software development. But actually what is this pipeline process? It's a method or set of principles for which development teams implement and deliver code more frequently and reliably. Continuous integration embodies a coding philosophy and set of practices propelling teams to implement small and frequent code changes into version control repositories, while the continuous delivery picks up where the CI ends and automates the application's delivery

Sharing Docker Containers across DevOps Environments

Docker provides a powerful tool for creating lightweight images and containerized processes, but did you know it can make your development environment part of the DevOps pipeline too? Whether you're managing tens of thousands of servers in the cloud or are a software engineer looking to incorporate Docker containers into the software development life cycle, this article has a little something for everyone with a passion for Linux and Docker.

Take Your Git In-House

If you're wary of the Microsoft takeover of GitHub, or if you've been looking for a way to ween yourself off free public repositories, or if you want to ramp up your DevOps efforts, now's a good time to look at installing and running GitLab yourself. It's not as difficult as you might think, and the free, open-source GitLab CE version provides a lot of flexibility to start from scratch, migrate or graduate to more full-fledged versions.

FOSS Project Spotlight: Pydio Cells, an Enterprise-Focused File-Sharing Solution

Pydio Cells is a brand-new product focused on the needs of enterprises and large organizations, brought to you from the people who launched the concept of the open-source file sharing and synchronization solution in 2008. The concept behind Pydio Cells is challenging: to be to file sharing what Slack has been to chats—that is, a revolution in terms of the number of features, power and ease of use.

Improving Linux Security with DevSecOps

Ask people who run IT departments these days what keeps them up at night, and they'll probably tell you it's security—or the lack of it. With the explosive growth of malicious attacks on everything from hospitals to Fortune 500s, security—not hardware, software and even staff—is what currently makes life miserable.

VMKings' VPS Hosting Solution

The management team of cloud provider VMKing, as developers themselves, found standard virtual servers not to be well tailored to the developer community—too much or too little space, insufficient security and no support for their preferred Linux OS(!).

CloudBees Jenkins Enterprise

Although open-source software excels at innovation and leverages the immense power of talented developers dedicated to solving difficult problems, the focus is rarely on enterprise capabilities, asserts CloudBees, the hub of enterprise Jenkins and DevOps. Fortunate for Jenkins developers, CloudBees, Inc., has announced CloudBees Jenkins Enterprise, a Jen
