I am not advocating for Microsoft. But Google is a cloud service too, which is what I meant by “trend.” Their business suite is mature, but they must face the harsh reality that the world is still and sadly not only governed by money but primarily by Excel. 
Yes, but about 10 years ago, there were increasingly more small customers who realized that having their own server in the corner wasn’t very smart. Many of them used Windows Terminal Server in external data centers. This trend has even faded in conservative Germany, and now the cloud is no longer taboo. However, nobody is really interested in “cloud” as a term; it’s about purchasing a service, being able to work with it, and reducing the technical aspects to a minimum (especially the operation of the software).
Of course, “trends” implicitly means that, by definition, they don’t apply to every company. Just as one Windows customer has succeeded with Linux, there is also a market for the reverse direction. As is well known, the city of Munich is currently doing this.
LiMux failed, as it often happens, due to poor planning, inefficient project management, and changing political guidelines. However, merely using open source in a thoughtless and deliberate manner leads to no progress either.
NextCloud, for instance, is a great product, but I know many customers who haphazardly run the product on some remote servers without proper security measures, ultimately experiencing failure.
In this respect, it seems logical to leave complex technologies to specialists. Whether it’s Google, Microsoft, Zoho, or whoever is almost secondary. Although many customers simply don’t want to give up their beloved Excel, and certainly not their macros
.
In the case of “Nextcloud”: purchase it as a service and refrain from tinkering with it on your own.
I believe the amount of resources that major cloud providers invest in security 24/7 is often underestimated. Internal IT departments, even in large companies, can rarely match this level of commitment and expertise. Admittedly, negative consequences like vendor lock-in remain a significant and important concern, but this issue also exists with a purely open-source approach. Although there may not be a traditional vendor involved, you still find yourself, perhaps even more so, reliant on “specialists.”
And on the subject of costs: in times of corporate behavior policies, license management is becoming increasingly important, from a legal point of view it has always been, but it was often regarded as a trivial offence.
Privately one may hate subscription models, for companies the purchase of services is much easier and the topic of license management is unnecessary because each user is billed automatically. And since “Cash is king” OpEx versus CaPex is playing an increasingly central role, which is becoming increasingly important in corporate decisions, even in smaller companies. Commercially and technically simple upscaling and downscaling is more important than ever, especially for startups.
