There is still a lot to do, but there are still important questions to answer and a lot of homework to do, but that much is clear: Cloud computing is in the process of fundamentally changing the way we operate and use IT. For many companies, cloud computing usually focuses on cost aspects.
The cloud gives them the perspective to significantly reduce investments in IT, especially in expensive infrastructure of data centers, in their premises, air conditioning and administrative staff. In the cloud model , companies pay primarily for the actual use of IT services; they do not have to invest in hardware, software, qualified personnel and know-how, regardless of their usage.
The dream of the empty server room
This opens up a hitherto unknown in IT flexibility. In this way, companies have dynamically scalable capacities at their disposal and are able to expand their IT systems in line with demand quickly and for a short time, without having to resort to their own resources.
And they can also do something that was not possible with the traditional way of using IT: if a short-term need has been resolved, for example during peak seasonal peaks, then the use of IT in cloud computing can be reduced again. The costs are due to the actual use, you do not have to invest in unused capacity. What also spares the liquidity.
Against the background of a considerable potential for savings, there is always the idea that in the long term companies could completely do without their own IT systems in order to only source IT services from providers. Here the old dream of the “IT from the socket” finds a new version and some cloud providers propagate quite a development of this kind: Investments in an in-house IT could even be dispensed with altogether.
Cloud is not there for everyone
Even if most do not want to go this far, at least for the foreseeable future, the cost benefits of cloud computing are undeniable. However, a key question is whether cloud computing is actually the cheaper alternative in all circumstances. And you should differentiate a bit.
On the one hand, one must not overlook the fact that companies also need a suitable IT infrastructure for the use of cloud computing. It makes a difference whether employees occasionally access the Web for information or whether a few hundred people are supposed to handle transaction-intensive processes via web access. Here, a suitably adapted network infrastructure is the prerequisite for, for example, a concept such as Software as a Service (SaaS) working.
Microsoft has managed to accelerate adoption of Azure with a combination of bona fides (CIOs that do a lot of business with trusted Microsoft vendors to help cloudify their infrastructure) and AI generation followed by smarts.
Google is increasing market share even faster than Microsoft (100% versus 61% according to Gartner estimates), and mainly through the combination of smart open source bets (such as Kubernetes and TensorFlow) and services AI industry.
A second advantage recently seems to be a liability, with Google seemingly saying that businesses can run more than Google if they are not stubborn as they are. However, it is clear that the slogan “run like Google” is a goal that can be achieved, something even most businesses can recognize.
