Linux vs Windows – the big server check

The duel between Linux and Windows may have an obvious victor on the home computer front, but the battle for server use paints a very different picture: since the beginning, Linux has defeated Windows, as usage figures show. But many users remain unconvinced by statistics and rightfully ask the question: what are the actual differences between the two platforms? [...]  

Module tests in software development

Module tests are one of the most effective methods of identifying as many errors in the source code as possible early on in the software development process. The special feature: the smallest isolatable components of a program are placed in a neutral test environment. If errors appear, it’s obvious they are occurring in the module being tested, which makes them easy to correct. [...]  

Docker Tools | The container platform eco system

Docker significantly simplified the use of software containers with its efforts at standardisation. The lean container platform is part of a growing ecosystem that provides users a wide range of application options in the realm of software deployments, orchestration of containers, and multi-container applications, as well as continuous integration (CI) and continuous delivery (CD). In this guide, we present the most popular Docker tools and extensions, and elaborate on the role of container technology within a digital infrastructure platform. [...]  

Docker tutorial: Installation and first steps

The open source container platform Docker is quite exciting to the open source community. As an alternative to hardware virtualizsation based on virtual machines, Docker has made the use of software containers acceptable outside of the Linux universe. In our tutorial for beginners, we break down the Docker trend from the ground up. With these clear, step-by-step instructions, learn how to install Docker, what the deal is with its images, and how to download these images from the Docker hub and run them locally as containers.

Archiving and Compression Using Linux

Archiving and compressing files contributes positively to the security and stability of a system. For Linux and other unix-like systems, there are countless free programmes with which you can create unaltered or compressed archive files over the command line and extract them as well. One of the classic packing programmes for Linux is tar. Today, the tool still counts as one of the leading archiving tools and plays an important role especially for compression tools, like bzip2.

What is CentOS? Versions & system requirements

Finding a suitable operating system that meets your own requirements is usually not very difficult in the private sector. Most of the time, it’s just down to personal taste whether you favour Windows, macOS, or Linux. The search for a system solution for enterprise and server environments is far more difficult and complex. When selecting, factors such as long-term support, security, and cost play a decisive role. An often underestimated operating system for this sector is the RHEL derivative, CentOS. [...]  

Ubuntu: The Linux system for everyone

Whether a home PC, work laptop, or website server – without an operating system, the management of hardware resources wouldn’t be possible. Windows systems have proven themselves over the years, and Apple computers run with Mac OS X as the standard, but Linux distributions are no longer a niche in the server environment. Ubuntu, for example, continues to build on traditional open source structures, but over the years, has developed into a multimedia platform that’s characterised by more than just user comfort. [...]  

A comparison of different servers

Carry out a server comparison and you will notice that website operators have a large selection to choose from. Professional hosts offer virtual, dedicated, and cloud based servers in different performance levels. How do these server models differ from one another? What features does a root server have in comparison to a managed server? Which type of hosting is best for your web project? Take a look at the overview. [...]  

Server Containers: virtualisation without emulation

The introduction of Software containers is widely regarded as a revolution in server administration. The idea of isolating applications in virtual runtime environments is nothing new, but with platforms like Docker, users can enjoy extensive functionality, which facilitates working with server containers. So, what exactly can application containers do? [...]  

Screenshots on Mac and Windows

What exactly is a screenshot? How do you create one? And how do the different screenshot shortcuts work when trying to create screenshots on Mac and Windows? Besides the built-in features on operating systems, what are the other, third-party options when it comes to screenshot tools? We’ll take you through our introductory guide to making screenshots and the best keyboard shortcuts and screenshot programs to help you. [...]
