Companies that decide to move to the cloud often have the impression that they are facing a Herculean task. The path of cloud transition seems long and rocky to many IT decision-makers. Legacy IT systems, have been performing their service in enterprises for decades. This enterprise software and hardware was often designed for specific tasks and over time added other applications that were important to the operation of the business.
Many IT managers have a great deal of respect for making changes to these systems because of the complexity of these organically grown enterprise monoliths. This is because the systems must be retested and restarted for each addition step. In addition, every change to corporate IT leads to a great deal of effort in the form of internal training to familiarize employees with the new features in the systems.
Nevertheless, in many cases there is no way around an IT reorganization. With increasing digitization, the demands placed on corporate IT are growing. These include, for example, a high degree of automation or the processing of large volumes of data in real time (big data analytics). Old applications are too slow, too rigid, too user-unfriendly in an economy that is changing ever faster.
On the way to the cloud, a structural change can thus begin in the area of corporate IT. From compartmentalized IT silos that want to be involved as little as possible in business processes, departments are gradually developing that can help shape the next steps in the company's development on an equal footing with management. With this new role, the IT department can become a business innovator within the company and ultimately anchor digitization ever more firmly in the company's business model.
The 5 R's of cloud transition
IT systems are now integrated into all of a company's processes. At the same time, companies cannot stop regular operations during the realignment of IT systems. The resulting economic damage would be too great. For this reason, cloud transitions are always "open-heart surgery" for everyone involved.
In order to minimize the risk to the company's ongoing operations, the transition from the old world, in which the company's applications were hosted on its own servers, to a new world of the cloud in many cases takes place gradually. And it takes the form of many small transitions. The sum of many small individual steps results in an overall concept: the digital transformation of the company.
The analyst firm Gartner has divided the different types of transitions on the way to the cloud into five different areas - the so-called "5 R's": Rehost, Replatform, Revise, Rebuild and Replace.
