What is a VPS (virtual private server)?

A virtual private server (VPS) is a compromise between shared hosting and a dedicated server. The VPS product allows web hosts to combine the strengths of both hosting models in one, cost-efficient IaaS solution. We’ll take a closer look at this hosting solution, demonstrating how a virtual private server works, exploring the advantages and disadvantages of it, and deciding who the model is best...

Four current Raspberry Pi alternatives: Single board computers by comparison

Raspberry Pi is the first choice for do-it-yourselfers around the world when it comes to single-board computers: It’s small, cheap, and meets most server and media center requirements. But more and more manufacturers are putting their own mini-computers on the market: Raspberry Pi alternatives want to set themselves apart with lower prices, more powerful hardware, or edgy and exceptional features....

MAMP: the local development environment for Mac OS X

If you’re developing a website, it’s important to regularly ensure that all the elements function as intended. Although there are no specific tools required for creating a basic info page with static content, it’s not possible to preview a project containing dynamic elements without some additional tools. The simplest solution is to use an all-in-one development environment like MAMP.

DNSSEC: internet standards for authenticated name resolution

Without the Domain Name System, users of the World Wide Web would have serious problems when trying to load websites and other online presences. It’s only thanks to this system that internet addresses appear in their trusted text format: they’re actually nothing more than combinations of numbers. The communication between browser and name server responsible for this isn’t actually as secure as you...

What’s the OSI model?

Those working with network technology are bound to encounter the ISO-OSI model sooner or later. This system subdivides communication between computer systems into seven different layers. Each of these layers is assigned a certain task. With the help of this layer model, subareas of abstract processes are able to be descriptively explained.

Resource-oriented web services based on REST

Combining different application systems has become increasingly important over the past few years. This trend is especially due to the increasing number of web applications being developed. In order to react to this trend, many different web services were developed that make data transfer across multiple systems possible. The Representational State Transfer (REST) is an architectural style that...

Server operating systems: history and today’s situation

Operating systems have gone through some major changes over the years. While their beginnings are rooted in more humble, purely text-based user interfaces, today’s options have evolved into complex software packages with graphical interfaces, comprising an elegant go-between for hardware and software applications. Users, who have long since been equipped with a keyboard and mouse, are able to...

VPN — secure data transfer through public networks

VPN implementations offer an affordable alternative for locally connecting networks, as well as making network resources available for external devices. In contrast to corporate networks, no private communication network is required. Instead, like the internet, VPNs rely on networks, and protect sensitive data through a process known as tunneling.

What is a web server? And which web server software is there?

The equation is simple - without it, there’s simply no web content: when a web server is out of order, then it’s no longer possible to call up any websites that are connected to it. Web servers are what allow online presences to reach the internet in the first place. But just how do these systems work? Which functions do the programs responsible for this task offer? And what’s an example of a good...
