Welcome to SpaceNet Clouderwelsch

Hardware cloud, IoT cloud, industrial cloud, multi-cloud, hybrid cloud ... In connection with the trend towards cloud computing and digital transformation, we are overrun with new technical terms and trendy buzzwords. In addition to cloud topics, there are also plenty of other abbreviations, technical terms and buzzwords in IT.

In our glossary, we want to unlock the secrets of communication around and with the cloud and IT in general.

The glossary will continue to grow. So keep checking back to discover new terms and get to know the IT industry a little better.


Agility enables an accelerated development process through less regulation.

from "to apply". Device on which an (->) application ("application"), typically a software solution, is permanently installed.

An autonomous system (AS) refers to a network part of the Internet. Each IP address belongs to exactly one AS, and it must be known how to reach each AS on all major network nodes worldwide.

Every Internet user has a so-called "default route" on their router, which usually has the simple content: "Send everything you don't know to your provider". The (real) providers don't have this. They have to "know" which package belongs where. The grouping in AS makes this work much easier.

Augmented reality = overlays in our (screen) reality.

The Parkometer AR app (which makes it easier to find your car again) is super practical, but it's worrying when zombies aren't walking through the streets looking left and right, like in Pokémon go

CeBIT is an IT trade fair in Hanover.

The trade fair began as a sub-exhibition of the Hannover Messe. This developed into perhaps the most important IT trade fair on the planet for around 30 years. In 1995, Bill Gates presented Windows95 to 755,000 visitors. And today? Well... since digitalisation has become a topic for every trade fair, CeBIT has become less and less important and was therefore discontinued in 2018.

CIO stands for Chief Information Officer.


CISO stands for Chief Information Security Officer, formerly Central Information Security Officer as opposed to LISO.


CLI stands for command-line interface.

Cloud Act stands for Clarifying Lawful Overseas Use of Data Act

Cloud Act ( Clarifying Lawful Overseas Use of Data Act) is a United States amendment to the Stored Communications Act with regulations on the collection of data in (from the US perspective:) foreign countries.

About Cloud Act

The data generated during the backup is not stored locally, but in the cloud. The data is transferred via the internet connection. The disadvantage of this method is that the internet connection must be large enough to transfer the data. This incurs additional costs. Advantage of the method: No investment in hardware is required and the service can be operated with minimal administration effort.

Cloud storage is a service model in which data is maintained, managed and backed up at a remote location and made available to users via a network (usually the Internet).

When storing data in the cloud, it is sensible and secure to encrypt it before it is stored. This technology is called cloud storage encryption.

Cloud-to-cloud backup involves copying data from one cloud service to another. It makes sense to back up data in the cloud online, i.e. with cloud backup, as the cloud services are usually connected to each other with very high bandwidths.

There are countless answers to the question of what is meant by the cloud and every day new cloudy terms are added, which we refer to as "Clouderwelsch". With our Clouderwelsch phrasebook, we aim to summarise the most important buzzwords relating to the cloud in an understandable, practical and neutral way.

CNOBI domains are top-level domains ending in .com, .net, .org, .biz and .info.

Compliance means that a company always adheres to certain rules of the game. In the IT sector, a company has to comply with legal as well as internal and contractual rules in practice.

And these are usually really complicated, otherwise IT would really simplify the life of a company :)

About digital bonus

Digital transformation refers to the phenomenon of economic and social changes triggered by modern IT concepts.

What digital technologies are changing in our lives. So the printed book becomes an ebook, (i.e. the printers die and the data centres flourish?), the doctor's consultation takes place via Skype and the conversation with the colleague in the same room via e-mail (with CC to the boss), but also completely new business models. It is no longer simply objects that are produced and sold, but only the benefits (e.g. car sharing, cycle minutes).

GDPR is the General Data Protection Regulation, the EU's "data protection law".

EU Regulation 2016/679 of the European Parliament and of the Council of 27 April 2016 on the protection of natural persons with regard to the processing of personal data and on the free movement of such data, and repealing Directive 95/46/EC (General Data Protection Regulation).


DPO stands for data protection officer.

Bavarian State Office for Data Protection Supervision


ECO is the eco Association of the Internet Industry.




"Git" means "git" in English. However, a Git repository is not a directory for managing such files, but for managing versions of files.

The whole thing was the brainchild of Linux inventor Linus Torvalds.

ITaaS goes beyond the purely technical provision of IT services and also includes strategic aspects.

For some service providers, an extended service will also be a "digital business model as a service" in the future.

The PUE value provides information about the energy efficiency of a data centre.

The value is calculated as the quotient of total power consumption and IT power consumption. Mathematically, it is clear that this figure is always greater than one, even if a few marketing strategists would like to see smaller PUEs. The closer a PUE value is to 1, the more energy-efficient a data centre is.

How to determine the PUE

A public cloud is based on the standard cloud computing model, in which service providers make various resources such as applications (Software-as-a-Service, SaaS), complete computing platforms (Platform-as-aService, Paas) or IT infrastructure such as storage or servers (Infrastructure-as-a-Service) available to the general public via the Internet.





Service Level Agreements (SLAs) typically regulate the minimum availability of a service.

Statistically speaking, technology at the lower level fails time and again, be it power, cooling, network connection, computer and storage hardware. In order to achieve higher availability, the provider must take precautions to ensure that services do not fail simply because components fail. This includes failover solutions and the creation of redundancies in the components. The higher the SLA value, the higher the production costs. Please note: If an annual SLA of 99% has been agreed, this means that services may fail for a full 24 hours within 100 days without breaching the SLA. At 99.99%, this is still almost one hour per year.

After the government SETI programme was discontinued in 1999, the search for extraterrestrial life was shifted to the army of individually operated PCs on the Internet as an innovative project and is therefore regarded as the first cloud project.

SDN separates all tasks in the network from any hardware with the help of virtualisation (cross-reference).

It is much easier to graphically define a network connection with a mouse than to physically walk through a data centre with a cable drum and screw firewalls and routers into IT cabinets. The basis for SDN was laid at Stanford University.
