An off-the-shelf car is out of the question for Frank. But he is also prepared to invest time and money in the necessary modernization. Unlike Klara, Frank is very much concerned with "the" car - namely his own. His car is where the value lies.
Back to Cloud...
In many companies, we find a similar starting position. It is not uncommon for the greatest and most business-critical value of applications to lie in the specification and individualization that has historically been carried out.
These highly specific individual applications can be found in every IT landscape. Not all of these applications can be moved to the cloud without further ado. Older applications in particular often require costly and time-consuming conversion before they can run satisfactorily on a cloud platform. The offerings of cloud hyperscalers, on the other hand, rely on standards - there is rarely any room for negotiation in operating and service models. However, many companies need a customizable environment for their special and individual solutions and the associated services.
Replacement or substitution with standards is out of the question, costs the competitive advantage and or is considered extremely risky.
In this case, the existing (partial) landscape can be raised 1:1 to a modern cloud level. It is possible to connect an existing data center with the data center of the cloud provider via a virtual connect, also known as a layer 2 stretch. Applications can then be transferred individually. IP addresses do not have to be changed in the process. Smooth continued operation is therefore not jeopardized. In short, this makes the successive transition to cloud technologies possible.
"So it depends."
Klara and Frank are just two examples. The starting situations that prevail in companies are as diverse as the companies themselves. Transition consulting is therefore the be-all and end-all of any move into the cloud. Only those who know their starting position can make efficient cloud decisions.
