Simply replace? Without sacrificing quality or availability? This will soon be a reality for the existing Data Center, Data Network and Voice Network departments thanks to public cloud offerings. In the areas of application support and application development, an increase in efficiency can even be expected thanks to cloud technologies. We can imagine the following scenarios for the other areas of IT organizations:
In direct contact with end users, the use of cloud technologies will change little in terms of visible processes. Although chatbots or self-service elements help to automate some of the tasks, individual user support by specialists will remain indispensable for many questions.
Application Management and Maintenance
High savings can be achieved with the public cloud in the administration and maintenance of the software used in the company: Processes optimized by cloud solutions during software development as well as application administration can achieve higher performance with the same number of employees. This only works if appropriately integrating methods are used and cultural changes are taken into account.
Server Management and Data Center
Without question, the most serious impact of the public cloud on our IT organizations will be visible in the areas of server management and data center operations.
With the use of cloud-based as-a-service solutions, server management tasks are practically completely outsourced. Whereas with IaaS (Infrastructure as a Service), for example, the import of patches or regular anti-virus scans remain with in-house IT, hyperscalers take over these tasks completely in the SaaS (Software as a Service) and PaaS (Platform as a Service) expansion stages.
In either case, there is no need to procure hardware. There will be a transitional period for data centers operated in-house. However, it is foreseeable that this will also be completely disrupted by the cloud. Exceptions may be individual islands with decentralized data processing, e.g. edge computing for processes on machines or control units.
Many of the traditional functions can be reduced by the cloud applications. In return, new functions such as the support of IoT devices or VR glasses will be added. The overall effort compared to previous solutions will remain constant.
Without data centers and their own servers, network support is becoming less important. In the office sector with connected peripherals such as printers, scanners and other devices, however, smoothly functioning networks are still immensely important.
The fact that companies develop their own software will continue to represent an important economic factor in the future. The use of cloud technologies should additionally strengthen the players here: They are the ones who improve internal processes, drive innovation and develop decisive competitive advantages for the company.
