The private cloud or is it the public cloud? What is cloud computing? Before this article goes into the two different forms of cloud computing, private and public cloud, it should first be clarified what the generic term is all about. Cloud computing is the term used to describe the shifting of data, systems and applications to a cloud, so that these, together with the necessary IT-based resources, are made available flexibly and on demand. This provision takes place via a network, such as the Internet. Cloud computing offers the added value that installations on local computers are superfluous for the user.

The advantages are that a research question can be illuminated by several research methods. The advantage of the thesis is that you can shed light on a question in two ways and make findings that were not possible on purely qualitative or quantitative research (Roch 2017). Different variants of the mixed method approach There are different versions of the mixed method approach. To do this, look at the following illustration.
