Flexibility on the market always also means flexibility in one’s own ICT equipment and systems: Processing power and server capacity need to be able to cope with short-term demand surges, the infrastructure always has to be up to date, and security solutions must be state-of-the-art at all times – while keeping as little capital tied up as possible. However, in many companies it is obvious that ICT cannot keep pace with the speed of market developments. Instead of providing optimum support for business processes, ICT becomes a bottleneck in critical phases. Against this backdrop sourcing, the outsourcing of parts of ICT to external specialists, can deliver significant benefits for the company. This also applies to the flexible sourcing of software, processing power or ICT infrastructure services from the cloud.
