Schools, public authorities or small businesses can also profit from them. Two examples of typical application...

Digitalisation: shape the future sustainably with Green IT Solution

Digitalisation: shape the future sustainably with Green IT Solution

Germany, with its focus on the automotive industry, is under increasing pressure in the global economy. Until now, the main threat to the competitiveness of manufacturing organisations was lower wage costs abroad: whether nearby or further afield. Previously, the most important argument for Germany as a production location was the excellently-trained workforce and globally-recognised engineering achievements which, when combined with precise and mature manufacturing technology,...

Air conditioning for data center

Air conditioning for data center

Where waste heat is produced, cooling is necessary. Data centers are particularly genned up on this: in a data center, hundreds of switches, CPUs, RAM modules in the terabyte range and power-hungry GPUs perform their duties. Without the appropriate expertise, a correspondingly poor air cooling of server racks & co. threatens - and that can become expensive very quickly. The importance of air conditioning in data...

Clouds are made of steel

Clouds are made of steel

Cloud Computing - today, in part two of our series, I would like to look at the three service models and the deployment models used in cloud computing. The infrastructure level is the base and provides the functionality on which the other levels are built. A well-known offering in the IaaS area is, for example, the Amazon Elastic Compute Cloud (EC2). Comparable with hardware you buy in shops, you can book a virtual machine (VM) at Amazon, which acts like a new computer: usually operated with Linux (but here as well, the user is free to decide and can also use other operating systems), you can log in to this machine and find nothing apart from a freshly installed operating system.


What are clouds?

What are clouds?

We’ll be lucky if anyone reads this sentence to the end, cloud computing is old hat after all. But that just depends! The truth is, all larger (IT) organisations have something to say about it, the young and successful in Berlin who’ve launched a startup in this sector (or work in one) - or privately, most smartphone users already take advantage of cloud services, perhaps without realising it: Sharing services (photo sharing for family members,...), backups, media data (music) as well as address books and calendars with various providers - this can certainly be seen as a cloud computing.


Used hardware: don’t dump it – sell it!

Used hardware: don’t dump it – sell it!

If hardware, bought years ago, has reached the end of its journey, it belongs on the rubbish dump – doesn't it? By trading in used hardware like a Cisco purchase, you can still make money out of hardware you consider to be outdated and, at the same time, avoid creating electronic waste – with almost no effort at all. Old is not obsolete Perhaps you...
